摘要:
A novel MOSFET circuit and method of manufacture utilizing a double ion implant process for manufacturing a low voltage high performance n-channel device that includes an enhancement transistor inverter combined with a depletion transistor load. The process starts with high resistivity material and uses a first ion implant process to dope the field region and to give the required threshold voltage for an enhancement device. A second ion implant is used to dope the channel region for the depletion device.
