To those unfamiliar with "III-V": Think GaAs (Gallium Arsenide) and friends.
gallium arsenide (GaAs) has six times higher electron mobility than silicon, which allows faster operation... Conversely, silicon is robust, cheap, and easy to process, whereas GaAs is brittle and expensive, and insulation layers can not be created by just growing an oxide layer; GaAs is therefore used only where silicon is not sufficient.

- sliverstorm 12y agoBetter than "Gaas Valley", at least.

- lmm 12y agoI think it's just the extra word. "Gallium Valley" sounds pretty cool, and "Arsenide Valley" sounds like a Bob Dylan song.
- higherpurpose 12y agoThat doesn't sound like good news for Intel chip prices.
- hga 12y agoIn many way's Moore's Law has been a law of economics. Look at the charts in the article; Intel will at least intend to continue the drop in cost per transistor, even if the price of a mm^2 of wafer continues to go up.
- kolanos 12y agoWill Intel be producing its own III-Vs or will it be sourcing it from somewhere else? Who are the major producers of III-Vs?
- quarterwave 12y agoCrystalline III-V channels can be grown epitaxially on silicon substrates, with buffer layers to grade the strain due to crystal lattice mismatch. With silicon wafers heading to 450mm diameter the economics would argue against native III-V substrates. One advantage of native III-V substrates is they are semi-insulating (very high resistivity) so there is no need for transistor isolation wells. However, insulated substrates could be obtained on silicon by means of wafer bonding with an intermediate dielectric layer.
