(MOD NOTE: Started a new topic for this discussion to continue. Please remember the 'no sci-fi engineering' provision of rule 1.9. Have fun!)
Also, since I'm thinking about surface operations on Venus, the state-of-the-art in high temperature electronics has advanced quite far in the past decade. Its now possible to buy off the shelf chips from vendors designed to operate at the 250-300 C range. Meanwhile basic functionality has been tested at and beyond the temperatures needed for long-term surface operations on Venus: http://www.grc.nasa.gov/WWW/SiC/ http://www.gizmag.com/extreme-silicon-carb...ctronics/16410/ http://www.grc.nasa.gov/WWW/SiC/publicatio...Contact2010.pdf Another decade or so and a long-term Venus lander could be possible with (practically) off the shelf electronics! |

GE and New York State are moving from 100mm to 150mm wafers for SiC:

I'm not even sure GE is the leader in SiC integration. Nonetheless, the fact that the industry's already moving to 6" wafers for SiC does sort of reiterate my earlier point that devices will be VLSI from the get-go with no interregnum period where you have to cobble CPUs together from multiple discrete few-T chips. |
