Frequencies

Hi Hagen! What are the frequencies you get right now simulating your gates with the parameters: n-device p-device C_ja 3*10^-4 pF/um^2 5*10^-4 pF/um^2 Cjp 4*10^-4 pF/um 4*10^-4 pF/um Just for curiosity Cheers David

QtFlow and standard gate design
by David Lanzendörfer 25 Feb '18

25 Feb '18

Hi Until I've gotten the features back I've broken by splitting up QtFlow into more modular submodules for building them with CMake you can use Magic for designing the first gates: http://www.ece.iit.edu/~eoruklu/courses/ece429/tutorial/magic.html I've got a Qt5 based Magic editor which understands Magic so we will be able to pick up where we leave with Magic and go on with QtFlow, as soon as the tool is being repaired. Also today I've advertised QtFlow during the Twitch-Stream of Noopkat and some folks already have git clones the project and promised to "bombard me with pull requests" (will see whether they keep their promise) Anyway. Tomorrow I will start doing some simulations of the drive-in process step in Octave and will update the LaTeX files for the process spec accordingly. For all who didn't attend the mumble session (which was basically everyone except Hagen and me). The tasks for this week: * Getting a formula for the dopant concentration in the n-well for a given time and temperature * Rework the dopant specification (top to bottom) based on specs from Hagen resulting from his simulations of his logic gate designs with the worst stacking numbers (4 transistors in series!) * Working on QtFlow Cheers David

Values: pirate pad

Hi We're going to collect the target parameters for our architecture here in this pirate pad: http://piratepad.net/eFacTaaVT5 Then I check whether they are realistic from our physics point of view. Cheers David

Well depth, mathematics
by David Lanzendörfer 25 Feb '18

25 Feb '18

Hi I've now gone through the theory for forming n/p-wells and it seems we have to do a diffusion simulation of the partial differential equations called the "continuity equation"/ Or does someone have a more specific equation already around which is a specific solution to the case of Silicon+Boron and Silicon+Phosphorus? If yes, could you maybe hack a piece of LaTeX with it as content? Cheers David

Diffusion

I'll be putting this into the LaTeX file in the chapter "Diffusion" for calculating the drive-in temperature and time: http://slideplayer.com/slide/12275641/ I'll notify you when I'm done doing so, then you folks can verify my numbers. Cheers David
