A major improvement came with the introduction of polysilicon self-aligned gate technology in 1968.[9] Tom Klein and Federico Faggin at Fairchild Semiconductor improved the self-aligned gate process to make it commercially viable, resulting in the release of the analogue multiplexer 3708 as the first silicon-gate integrated circuit.[9] The self-aligned gate process allowed tighter manufacturing tolerances and thus both smaller MOSFETs and reduced, consistent gate capacitances.
