Stepper, DMD chip
by David Lanzendörfer 07 Apr '21

Hi What do you think about using the DLP2000 for the first version of my exposure unit? It could already make structures down to 50um with a die size of 1cm x 1cm Cheers -lev

Maskless Lithography

Hi So Mouser has DMD chips from Texas Instruments, with multiple of those chips you already can achieve around 20 micron feature sizes and lower on a 1cm x 1cm die... For 50 Euros a chip... NOT 4000 Euros... I think it's a no brainer to run with DMD chips for now... Cheers -lev

GloveBox
by David Lanzendörfer 05 Apr '21

05 Apr '21

Hi So I'm right now tinkering together the GloveBox in FreeCAD. Attached is a little preview. Material wise we're much cheaper than the alternatives found on global supply[1], since I'm using standard aluminum profiles, acrylic glas and other off the shelf materials like perforated aluminum sheets[2], and for the air filtration I will use an inexpensive pump with HEPA filter from eBay[3]. Cheers -lev [1] https://www.globallabsupply.com/Two-Port-Simple-Closed-Loop-Glovebox-Acrlic… [2] https://hardware-warehouse.co.uk/Round-Perforated-Anodised-Aluminium-Sheet-… [3] https://www.ebay.com/p/19020368277?iid=373004598128

Should I join the mumble session this weekend?
by Pavel Nikulin 04 Apr '21

04 Apr '21

Hello list, I finally got a first human response from JBD about the matrix. I informed David, and am awaiting his reply. I'd like to speak about about approaching them, and a bit on your funding. I believe you already scoured through all, and everything with regard to funding opportunities, but I believe the big news of the last few months open a few more avenues for you. I believe having to chase funds again will be a big distraction for you, as expected, but the cost benefit on that, and any chance on commercialization fade if not pursued withing months.

microLED matrix samples
by David Lanzendörfer 31 Mar '21

31 Mar '21

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 -lev

Meeting minutes 2021.mar.14.
by Ferenc Éger 14 Mar '21

14 Mar '21

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
