New copyvio problem
A large portion of the article and associated figures are takes straight from without credit. a13ean (talk) 17:39, 1 March 2012 (UTC)

Problem with References
Many of the sources are from the Yale e-lab website that is now hosted by Purdue. The references in this article must be updated as the links do not work. "July 2011: Eugenio Culurciello is now an Associate Professor at Purdue University Weldon School of Biomedical Engineering. e-Lab has now moved to Purdue!" I will try to come back and update sources. I am engineering student, so I have access to information on the silicon on sapphire process. Bobbie112 (talk) 01:53, 11 December 2013 (UTC)

HP handheld calculators used bulk CMOS, not SOS
HP used SOS in various desktop computers and peripheral (9800 series), but not in handheld calculators. HP used bulk CMOS in the 25C, 19C, 29C, and 41C family. The Voyager series (10C, 11C, 12C, 15C, 16C) initially used the same bulk CMOS "Nut" CPU as the 41C, along with the bulk CMOS "R2D2" (RAM/ROM/Display Driver) chip. Over the years there were a number of redesigns, which have all used bulk CMOS, with recent versions of the 12C using commercially available Atmel ARM.microcontrollers rather than HP custom. https://www.hpmuseum.org/journals/hp41/41bc.htm Brouhaha (talk) 07:33, 12 March 2020 (UTC)

Radiation Resistance
Need to understand how standard NMOS and TTL were built. P-type "islands"(wells) on N-type Silicon on top of N+ Ground attachment via Gold-Silicon alloy. This forms a P-I-N diode with photoelectric properties. These "stray currents" are minimized by having a thinner lightly doped N-layer. 2600:100F:A020:F420:E8D3:194F:55B:4A2D (talk) 05:02, 2 July 2024 (UTC)
