Hello Everyone,

Summary of the mumble session:

Participants: eegerferenc, hsank, leviathan, PhilippGuehring, tatzelbrumm

Agenda:

- website: to be done. R:eegerferenc

- Maskless lithography: see David's email

- SKY130: Current shuttle missed due to DRC issues could not be fixed in 
time. Next shuttle is expected at mid-2021. Possibly analog design will 
also be included.

- EC/Horizon: No progress on the draft was made. Inputs welcome.

- LS50U: Germanium point-of-contact transistor is considered as a 
first-step experiment due to the absence of toxic or controlled 
substances or special equipment.


Regards,

Ferenc

Hi,

My Libresilicon Testwafer design that 
was planned for the first Google 
Shuttle run was unfortunately moved 
due to DRC issues in our standard 
cells from the first shuttle run to 
the second shuttle run, somewhen mid 
2021.

This is my design test-wafer design:
https://github.com/thesourcerer8/carav
el-stdcelllib-stdcells/

There are 5 more shuttles planned, so 
for anyone who is interested in 
creating additional projects for the 
Sky130 process, I have collected a 
list of videos and important links 
that explain Skywater, the Caravel 
Management frame, Openlane the RTL2GDS 
flow:

Hi friends,
I have one question about the Skywater 130nm open shuttle program.
I am a PhD student in Iran, Can I participate in this program (Because of
US sanctions)?

Hi Seyedali
I'm not sure whether the sanctions concern individuals or only companies
working for the Iranian government.
We'd need to ask Skywater and Mohamed Kassem, whether that would be possible.
I BCCed him in this reply.

Cheers

Hello Everyone,

Summary of the Mumble session:

Participants: Devon, eegerferenc, hsank, leviathan

Agenda:

- Ascent (https://www.ascent.network/access/): Possible cooperation by 
removing proprietary parts from Ascent's CMOS flow and making it 
LS1U-compatible. If succeeds, this may speed up taping out Pearlriver 
and its testing/characterization.

- Maskless lithography: INL lab is still inaccessible due to COVID. 
Meanwhile, do ideation and design on a primitive version targeting LS50U 
and low-cost implementation (similar to Sam Zeoloof's work). Platform: 
MLL redmine environment 
(https://redmine.libresilicon.com/projects/maskless-lithography/)

- website: agreed on formatting, to be published. R: leviathan

Regards,

Ferenc

Hello Everyone,

Summary of the Mumble session:

Participants: eegerferenc, hsank, leviathan, tatzelbrumm

Agenda:

- LS50U/MLL: It is proposed to make a maskless exposure unit based on 
JBD's uLED panel targeted at 50-100um MFS, and make it available bundled 
into a "DIY Microchip Fabrication Kit" containing everything needed for 
a basic process. Details discussed so far:

 ?? * Substrate: custom, 1-2cm rectangular "wafers" in order to make 
alignment easier and to fit into a small tube furnace. Similar, but 
polycrystalline offerings exist for solar panels. Finding and quoting a 
supplier is in progress.

 ?? * Exposure: JBD uLED panel + simple projection/reduction optics + 
3D-printed framework for alignment, into which the chips can be slided in.

 ?? * Furnace: cheap second-hand tube furnace, or a tube furnace heater 
with retrofitted quartz tube and control electronics (backup plan). 
Metal-lined, graphite-lined or gas-heated types are to be avoided due to 
contamination issues.

 ?? * Chemicals (HF, B, P, As, acidic cleaning agents, ...): Ordered in 
bulk and repackaged for distribution to overcome that chemical reagent 
suppliers don't deal with individuals.

 ?? * Funding: Initially, crowdfund with unit price based on the 
expectation of at most 2 customers (semiconductor-related crowdfunding 
tends to fail), then lower the UP if more customers come. Also, plan B 
shall be formulated.

 ?? * Legal background: form a limited-liability company to handle the 
stuff.

Discussion is expected to continue until next Sunday, when things are 
expected to be written down. Comments on mailing list or participation 
in the Mumble session are welcome.

Regards,

Ferenc

Great to hear you guys having so much progress.

By any chance, have anybody heard of Domicro BV? A Netherland based
microfab shop https://bits-chips.nl/artikel/small-series-of-chips-profitable-by-flexible-concept-minimal-fab/

Hi
No I didn't know this project.
Seems to be pretty much the final stage of what I was thinking about...
Can you get us in touch?
Having one of those machines would make it unnecessary to have access
to a clean room... It would be awesome!

Cheers

Hello Everyone,

Just another two considerations: Our target audience with this kit is 
the unit-radius citizen without significant financial resources (hence 
the 300Eur target price), so the following needs to be addressed:

- How to deposit the metalization without possessing a "real" sputter? 
Maybe a chemical process that leaves a solid metal layer?

- How to make the chip terminals accessible without possessing a "real" 
bonder (the dumbest functional second-hand unit is min. approx. 4000USD 
on ebay)? Mind the parasitic capacitance here...

Regards,

Ferenc

No, I don't know much about them, but what I wanted to suggest is to
get in touch with them, and try to get a reference to their clients
who operates those mini, and micro fabs.

Going through this industry body https://hollandsemiconductors.nl/ or
directly contacting those fellow
https://www.linkedin.com/in/matthijs-van-kooten-b59092118/?originalSubdomain=nl
https://www.linkedin.com/in/marcelgrooten/?originalSubdomain=nl

A tricky thing I believe will be the fact that you may be their
potential future competitors.

Hello List!

Last Sunday we talked also about
"Legal background: form a limited-liability company to handle the stuff."

Well, I vote for using a SCE [0] to fulfill this legal task instead of a
company.

A company is mostly owned be some individuals which rules the whole
process in a "capitalistic" way. And I do not thinks this form will
reflect our mission to bring the advantage of an open-and-free
technology to the masses.

In my opinion a cooperative fits better into our community-based
environment. We need at least five entities (persons or institutions)
from two different European Countries - a goal I guess we can reach
while our active members are all located in Europe.

So, the SCE can attract many members and give us a legal home for that.
Okay, on backside of the SCE, a higher effort is driving/leading this
cooperative because the SCE lives with the engagement of all of its
members. I understand this as an enrichment. :-)

Regarding the naming rules I propose

	"SCE LibreSilicon Alliance" as a suitable name

for our cooperative enterprise.

Some arguments for cooperatives also Wikipedia has [1].

Please feel free - even if your not from Europe - to give any feedback
which Advantages and Disadvantages do you see in setting up and driving
a SCE. Let's argue and find the best legal form to build a great
LibreSilicon community.

Live long and prosper,
Hagen.

Hey List!
AFAIK, ASCENT+ is already a cooperative, so if we could get out foot into that 
club, we would already have achieved that goal.
In addition, we'd get access to clean rooms and services across Europe.

Hello all!
I think ASCENT+ is not a Registered Legal Entity of its own, but just a project (the project members are legal entities). 

One problem with SCE might be that there is a start capital of at least 30000? needed.

Would it be enough to set up a registered society or coop in some country? E.g. in Germany registered society (eingetragene Verein, e.V.) or registered coop (eingetragene Genossenschaft, e.G.) does not need any start capital. They are legal entities which means that they can own things and do businesses. The big decisions are made by members and basically all the members have one vote.

Best regards,

  Jani

Hello Everyone,

I see two problems with that approach: first, they will be most likely 
unwilling to take responsibility for our grey-zone chemical toy, that's 
the purpose the idea of forming an entity came up for. Second, in my 
opinion, if we want to do serious things like presenting a product or 
service to the market in exchange of financial compensation (either 
for-profit or non-profit), at some point it will become unavoidable that 
we form something that is, on an administrative, business and legal 
level, more than a private citizen acting along direct interpersonal 
contacts in name of some group of other private citizens or an 
externally more-or-less obscure open-source project.

Regards,

Ferenc

I will totally support you on this.

While you all are EU, or EEC citizens, I believe a foreigner will
still need a legal entity just to do anything even in the liberal
Europe.

I'm stuck in the very same situation now while being stuck abroad for
the last year due to covid, and quarantines. Countries didn't spend
the last century making it hard to do business things without having a
business entity for nothing: getting things through the customs,
renting an office, doing even smallest transactions for services...
I'm running into that every day.

Regarding "[...] you may be their potential future competitors.": I 
think there is no cross-section between our and their scope at the moment:

- For LS1U, LS130 and any future LS nodes, where fabrication using 
equipment they make is desired, they will be most likely our supplier 
than competitor.

- For LS50U, we aim to make and sell "equipment" like them, the target 
audience is different: they aim for corporate customers with need for 
prototyping or small-volume production of complex designs for real-life 
applications, while LS50U is a large-MFS metal-gate PMOS-only "toy 
technology" without high assurance of reproducibility or versatility, 
aimed at raising attention of private persons and enabling them to get a 
taste of semiconductor technology before they move on to more complex 
designs (e.g. on LS1U) or more in-depth contribution to the project.

Regards,

Ferenc

Agreed.
Nicolas Cordero from ASCENT+ just came back to me.
The other laboratories haven't gotten back to him about my proposal
to adapt LibreSilicon to their equipment.
Considering how they're organized, they're clearly NOT a business
entity... Yeah. Maybe we need to found something like a company
in order to do trading.
I know someone here with an import export license, and will check
how much it costs to get one as well.
I guess it will go towards me incorporating a company here in Portugal,
so that I can send around chemicals and equipment, as we've discussed.

Cheers

Hello List!

This is our weekly announcement for the next Mumble Sessions on Sunday

	2021-03-28 @ 18:00 UTC.

Hi Pavel, hi list

So I now finally managed to find an apartment, which is not only cheaper than
the current, but which also includes a private garage space, which I can 
close.
Can I get a sample of a UV microLED matrix, so that I can build a prototype 
for a simple exposure unit in my new lab?

Cheers

The ones I know are all visible light. Making a DUV LED matrix will
require no less than use of a new material. Maybe a near UV will still
be possible with current materials.

The best would be to ask the man directly.

Hi
I've sent im a connection request on LinkedIn.
Maybe you can tell him to accept it, if you two are already connected?

Cheers
