in 1984 and 1985 the company i did final assembly of semiconductor manufacturing equipment for, received processed wafers that had not passed QC to use as test wafers from customers that bought their products. With the developed wafers it could be seen that the circuitry was inside not on top of the wafer. The chemicals had penetrated wafer in each step. Nothing was on the wafer surface. Maybe like stained glass is not like painted glass. My guess is the glass is porous as far as glass stain is concerned. And wafers were porous as far as the chemicals used for them then,

Semiconductor manufacturing equipment of the mid 1980s was used to spin the wafer as chemical streams or sprays were applied to create the layered images inside. Dopants altered the silica atomic structure to create N or P type properties that in the end left an electronic circuit inside a little square of glass called a fragment that was about the size of a square seen with 1/4 inch graph paper. Photoresist made possible the etching away of doped areas inside the thin glass like wafer. N and P type areas combined formed transistors in the maybe thousands or hundred or hundreds of thousands in tiny areas thanks to a microfiche mask used to expose the photoresist for the etching processes. Like one photograph negative sandwiched between two pieces of glass the mask was. But there were maybe about 200 little square identical images in each maybe 4 inch mask. Protected from contaminants and friction in between the two pieces of glass the film photograph negative was safe to use over and over. But special equipment was used to cleanse the mask to increase yield. Else too many of those little squares would be faulty and not an effective micro miniaturized circuit inside that black rectangular computer chip.

That substrate in that visualization is the same thing as the silicone right? In MEMS technology it's all about the silicone. The substate is cut from silicone. And all etching is happening to that silicone substrate wafer. They're not different things. Correct me if i'm wrong

Instead of R~λ/NA, R should be replaced with minimum feature size (CD) so CD~λ/NA so if the wavelength increases the minimum feature size increases and if the wavelength decreases ( frequency increases) and the minimum feature size decreases so smaller patterns can be put on the photoresist layer.

1. Smaller process nodes enable greater efficiency reducing the drain on batteries by electronics at a given performance level 2. We may as well continue to use the lithography industry's developed R&D resources until quick progress ends. Otherwise we'll have to rebuild the labs later on when chips are revisited. 3. Electrochemistry has very different problems, and there are no obvious improvements to be made on current technologies. Funding would go to basic (not applied) research and the chances of useful results would be extremely slim (not attractive to investors). 4. We should still fund basic research more, it's where the most important technologies come from. 5. We need better batteries, and current ones are terrible. There's quite a bit of money going into efforts to change that (both by reducing the need and improving the batteries).
