Abstract:
Field effect transistors for an SRAM cell can be formed employing n-doped gate electrode portions for p-type pull-up transistors. The SRAM cell includes a first series connection of a first p-type pull-up transistor and a first n-type pull-down transistor located between a power supply source and electrical ground, and a second series connection of a second p-type pull-up transistor and a second n-type pull-down transistor located between the power supply source and the electrical ground. Each gate electrode of the SRAM cell can include a respective n-doped gate electrode portion.
