> I have some notes on a semiconductor fabrication process with just sustainable inputs: Ethyl Lactate, Lignin-Vitrimer, Nitrogen, CO2, Laser-induced Graphene, A-CNT, PCLP Photo-cleavable Lignin Polymer, Hexyl Cellulose
Yeah, I was thinking of something like that. If there are fewer chemical components, recycling gets easier.
A biodegradable product out of biodegradable inputs would be great for computing
Before looking into Lignin I was looking at deoxidizing rGO reduced graphene oxide with hydrogen plasma.
I learned that the work functions of graphene and CNT are actually sufficiently different such that the graphene could be a substrate for CNT FET without the charge jumping out of the gate to the board. Salt apparently dissipates electric discharge about as well as silicon.
But a plasma process would probably have a lower yield rate unless there are masks, which are expensive to fab but maybe necessary to compete at production scale.
Monolithic chip fab is slower but the fabrication plant CapEx and OpEx are lower.
LCS SLM with LCoS, CO2 fiber laser / Yb Laser, plain old DUV
Some helpful prompts for a sustainablefactory agent skill:
Identify and redesign to eliminate production health hazards and environmental hazards
Find and compare sustainable alternatives, workarounds, substitutes for
Consider cellulose, graphene CNT and other carbon allotropes, CO2, nitrogen
We shouldn't post politics news on Hacker News unless they are tech-related... if we allow this, it will grow worse through time. I am here to read tech content, not politics.
This is an easter egg in The Sims 1 (2000). It comes up after playing with a family for over 100 in-game days, and shows each person involved in the development of the game.
My phone is an iPhone SE 2nd gen. It's much more ergonomic and I can use it with only one hand, typing text included. Previously I had an iPhone 6S, same screen size (4.7″).
Other iPhone models are giant walkie-talkies for me. They need one hand to hold them and another to type text or slide the screen.
