Abstract
Semiconductor devices, with especial reference to transistors with reduced turn-off times. This improvement includes a low-barrier height metal contact to one of the lightly-doped regions of the device as a replacement for the conventional heavily-doped region or high-low junction structure usually employed for the purpose of providing ohmic contact.
