Innovationspatents, processes, and products

Complementary logic devices — that is, devices that use currents both of electrons and of holes — have long been a goal of researchers designing gallium arsenide (GaAs) compound semiconductor devices. In silicon technology, the advent of complementary logic devices in the late 1960s cut those integrated circuits´ need for power. Chips generated less heat, and so could be packed more closely together on a board for faster performance. Computers thus became at the same time more power-efficient, less expensive, and faster.
