PhilippGuehring: Created page with "== Our roadmap == As of 2021, our tentative roadmap is the following: * Establishment of LibreSilicon Foundation in Europe * Finish LS1U technology node (incl. SPICE parameter extraction) * Development of ESD protection and pad cell library for LS1U * Development of a maskless lithography stepper, initially at least for 50um MFS, later for LS1U * Tech Demo: LS555 (design, MLL fabrication, testing) * Digital cell library for 1u MFS + digital tool..."

== Our roadmap ==

As of 2021, our tentative roadmap is the following:

* Establishment of LibreSilicon Foundation in Europe
* Finish LS1U technology node (incl. SPICE parameter extraction)
* Development of ESD protection and pad cell library for LS1U
* Development of a maskless lithography stepper, initially at least for 50um MFS, later for LS1U
* Tech Demo: LS555 (design, MLL fabrication, testing)
* Digital cell library for 1u MFS + digital tools (may be parallel to LS1U/LS555)
* Tech demo II: 8-bit Arduino-compatible MCU
* later ...
* Libresilicon Fabrication Service opens in EU
* later ...
* Development of LS130 technology node (incl. MLL capablity)
* Tech demo III: 130nm System-on-Chip
* ...
* Development of sub-100nm technology node (incl. MLL capablity)
* Tech demo IV: SOC made on LibreSilicon runs GNU/Linux

Eco friendly Polysilicon deposition (CVD)

2023-05-17T15:31:02Z

PhilippGuehring: Adding link back

So we asked Bing AI to crawl the web for alternative solutions for the Polysilicon deposition [[R&D challenge]] , and after some digging she found two research papers<ref>https://www.sciencedirect.com/science/article/pii/0040609085902536</ref><ref>https://www.sciencedirect.com/science/article/pii/S0927775703005582</ref>, from which she deduced a recipe using Siliclad®<ref>https://s3.amazonaws.com/gelest/sds/SIS6952.0_GHS%20EU_English.pdf</ref>, which is a liquid alternative to the very dangerous and poisonous Silane gas, however, we're still looking for a lab for verifying this recipe.

The recipe goes as follows:

# Prepare a silicon substrate by cleaning it with acetone and isopropanol, and then oxidizing it in a furnace at 1000°C for 30 minutes in an oxygen atmosphere
# Prepare a chemical system containing a water dispersible octadecylsilane-based chemical (such as Siliclad®) and a cationic surfactant (such as cetyltrimethylammonium bromide) in a solvent system containing a mixture of tertiary alcohols and diacetone alcohol. The concentration of the silane and the surfactant should be optimized according to the desired hydrophobicity and film thickness.
# Load the silicon substrate into the CVD chamber and heat it to 200°C.
# Introduce the chemical system into the CVD chamber as a vapor by using a bubbler or an ultrasonic nebulizer.
# Maintain the deposition for 10 minutes or until a uniform coating is formed on the substrate.
# Stop the deposition and purge the CVD chamber with nitrogen gas.
# Remove the substrate from the CVD chamber and cure it at 150°C for 30 minutes in air.

PhilippGuehring: Adding new solution

This side holds projects for which we welcome external help to contribute man power and machine access.

==Polysilicon==
Polysilicon is currently only done by using silane gas, which is highly poisonous and unfeasible for small scale manufacturing setups.
We welcome the help from material science students and labs to come up with alternative recipes which require less poisonous gases or
provide alternative chemical recipes for alternative gate materials with similar resistivity and temperature tolerance as polysilicon.

===Requirements===
* Liquid material deposition
* Can be done with lab furnace (preferably around 1200 degrees Celsius)
[[File:Labfurnace.png|500px]]
* No chemicals which get your garage SWATed
* Etching method should be provided which can be done in a garage

===Possible Solutions===
* Can we use https://futurezone.at/science/computerchips-honig-memristor-washington-state-university-neuromorphes-computing/401967797 instead of polysilicon?
* AI generated recipe: [[Eco friendly Polysilicon deposition (CVD)]]
