Best court document you've read in your life

Includes interesting info about Target shopping chain pulling surveillance video to identify a Tracphone buyer, surveillance drone usage in support of car-theft ring on Mare Island in the Bay Area, threatening the local Vallejo police department, Christian repent, you name it. And of course the obligatory dipshit move or two by the defendant in the criminal complaint, such as leaving his drivers license under the seat of a stolen car. Starts getting good around page 20.

That's the way things were about 25 or so years ago. Wafers with photoresist were exposed with machines using UV, which over the years used ever-decreasing wavelengths of UV, in equipment:436. 365nm, and 248nm, eventually reaching 193 nanometer UV. In the 1970's, entire wafer-masks (which covered the entire wafer) were used. This became impractical as feature-sizes were reduced. Step-and-repeat devices ("wafer-steppers) https://en.wikipedia.org/wiki/Stepper then allowed exposure of a much smaller portion of a wafer. (these eventually used mirrors, rather than lenses, because it is hard to process UV in a solid lens.) However, because the wavelength of light eventually became a large portion of the size of a chip feature (a line or a space) it was increasingly difficult to 'draw' the picture necessary to expose the resist on the wafer. Due to many ever-more-heroic technologies, it eventually became possible to use 293 nanometer wavelength to expose features far smaller than the wavelength itself, which would have been considered phenomenal in the 1970's. These days, EUV ("extreme ultraviolet") has been used for ever more small features. https://en.wikipedia.org/wiki/Extreme_ultraviolet https://en.wikipedia.org/wiki/Extreme_ultraviolet_lithography EUV is strongly absorbed by air, so such exposure is typically done in a vacuum. > > Is this using near-field optics?

None that I'm aware of. But EUV will take over from electron-beam: The latter is quite slow, and typically has been used mostly for making masks.

There was research and patenting in this area beginning in the 60-70s but I not seen any articles showing use.

For CPunks what's needed is a DIY Electron Beam Litho apparatus. Its basically an electron microscope in reverse. For relatively simple chips it could be more than adequate as its possible eliminates the need and complexity, chemistry, etc. for masks and can perform most all process functions (doping, implantation, etc.) and attain feature sizes commensurate with current foundary tech. AFAIK, its possible to build from used e-microscopes though maintaining calibration and linarity is something best learned in a working environment at someone else's expense. :) One of the main shortcomings of EBL is its low production rate since all features must be developed by "writing" them, like an old stylevector display, on the substrate. -------- Original Message -------- From: grarpamp <grarpamp(a)gmail.com> Apparently from: cypherpunks-bounces(a)cpunks.org To: "cypherpunks(a)cpunks.org" <cypherpunks(a)cpunks.org> Subject: Re: Open Fabs Date: Tue, 28 Jul 2015 22:20:41 -0400 > > Steve Kinney wrote: > > If a market is willing to pay enough to support and grow the > > project, it can be done.
