Ultra Low Power SubThreshold Device Design Using New Ion Implantation Profile
… aspects of integrated circuit design is doping profile of a transistor along its length, width and depth. Devices for super-threshold circuit usually employ halo and retrograde doping profiles in the channel to eliminate many unwanted effects like DIBL, short channel effect, threshold …

A new inverse-modeling-based technique for sub-100-nm MOSFET characterization
… effects, extensive use of non-uniform doping profiles are found in modem devices. Among these are the super-steep retrograde (SSR) channel profile, characterized by a low dopant concentration near the surface and a high dopant concentration at some depth from the surface, and the halo …

High-speed silicon electro-optic modulator for electronic photonic integrated circuits
… using a carrier lifetime reduction and a graded doping profile. A bandwidth of 1-2GHz has been demonstrated so far which is considerably smaller than the design bandwidth due to high series resistance. Modulators based on the forward-biased PIN structure without lifetime reduction have a low …
