GaN Manufacturing Meets Big Silicon


I have been talking about GaN on Silicon for several years because it offers a path to cost reduction in LED’s in the same way as silicon semiconductors. This year at Photonics West 2015, Aixtron presented its next generation 6-inch wafer system with all the automation that the semiconductor guys expect to be able to build GaN power transistors. The systems are configured as cluster tools... » read more

New Approaches To Better Performance And Lower Power


By Ed Sperling Until 90nm, every feature shrink and rev of Moore’s Law included a side benefit of better power and performance. After that, improvements involved everything from different back-end processes to copper interconnects and transistor structures. But from 20nm onward, the future will rest with a combination of new materials, new architectures and new packaging approaches—and som... » read more
