Abstract: Dual-gate memory cells and tri-gate CMOS devices are integrated on a common substrate. A plurality of silicon bodies are formed from a monocrystalline silicon on the substrate to define a plurality of transistors including dual-gate memory cells, PMOS transistors, and NMOS transistors. An insulative layer is formed overlying the silicon body of the memory cell. A layer of a high-k dielectric and at least a metal layer cover the silicon bodies and their overlying layers. Next, gain regions of the transistors are filled with polysilicon. Thus, a gate is formed on the top surface and both sidewalls of a tri-gate transistor. Thereafter, the high-k dielectric and the metal layer overlying the insulative layer of the memory cell are removed to expose the insulative layer. Thus, two electrically-isolated gates of the memory cell are formed.

Abstract: A method for forming first and second devices from first and second silicon bodies is described. A sacrificial layer allows gate regions to be defined with underlying insulating members. After the sacrificial layer and bodies are surrounded in a dielectric layer, the insulative member is removed from one of the bodies. After removal of the sacrificial layer, gate structures are formed. For one device, the gate surrounds three sides of the body, and for the other device two independent gates on the sides of the body result.

Abstract: A method for fabricating double-gate and tri-gate transistors in the same process flow is described. In one embodiment, a sacrificial layer is formed over stacks that include semiconductor bodies and insulative members. The sacrificial layer is planarized prior to forming gate-defining members. After forming the gate-defining members, remaining insulative member portions are removed from above the semiconductor body of the tri-gate device but not the I-gate device. This facilitates the formation of metallization on three sides of the tri-gate device, and the formation of independent gates for the I-gate device.
