| 20090140341 | INDEPENDENT N-TIPS FOR MULTI-GATE TRANSISTORS - Independent n-tips for multi-gate transistors are generally described. In one example, an apparatus includes a semiconductor fin, one or more multi-gate pull down (PD) devices coupled with the semiconductor fin, the one or more PD devices having an n-tip dopant concentration in the semiconductor fin material adjacent to the one or more PD devices, and one or more multi-gate pass gate (PG) devices coupled with the semiconductor fin, the one or more PG devices having an n-tip dopant concentration in the semiconductor fin material adjacent to the one or more PG devices, wherein the n-tip dopant concentration for the PG device is lower than the n-tip dopant concentration for the PD device. | 06-04-2009 |
