  • Patent number: 8581317
    Abstract: A silicon on insulator (SOI) multi-gate field effect transistor electrically Programmable Read-Only Memory (MuFET EPROM) includes a substrate having a dielectric surface. A first semiconducting region is in or on the dielectric surface. A source region, a drain region and a channel region interposed between the source and drain are formed in first semiconducting region. A gate dielectric layer is on the channel region. At least a second semiconducting region in or on the dielectric surface is spaced apart from the first semiconducting region. A first electrode layer comprises a first electrode portion including a transistor gate electrode and a control gate electrode electrically isolated from one another. The transistor gate overlies the channel region to form a transistor. The control gate extends to overlay a portion of the second semiconducting region.

  • Patent number: 8410519
    Abstract: An integrated circuit device that includes a plurality of multiple gate FinFETs (MuGFETs) is disclosed. Fins of different crystal orientations for PMOS and NMOS MuGFETs are formed through amorphization and crystal regrowth on a direct silicon bonded (DSB) hybrid orientation technology (HOT) substrate. PMOS MuGFET fins are formed with channels defined by fin sidewall surfaces having (110) crystal orientations. NMOS MuGFET fins are formed with channels defined by fin sidewall surfaces having (100) crystal orientations in a Manhattan layout with the sidewall channels of the different PMOS and NMOS MuGFETs aligned at 0° or 90° rotations.

  • Patent number: 7960234
    Abstract: One embodiment of the present invention relates to a method of fabricating a multi-gate transistor. During the method a second gate electrode material is selectively removed from a semiconductor structure from which the multi-gate transistor is formed, thereby exposing at least one surface of a first gate electrode material. The exposed surface of the first gate electrode material is deglazed. Subsequently, the first gate electrode material is removed. Other methods and devices are also disclosed.

  • Patent number: 7939393
    Abstract: Different performance MOSFET Fully Depleted devices can be achieved on a single chip by varying the Vt through ion implantation. The integration of multiple Vt can be achieved through the selection of a metal gate stack with suitable effective WF for one semiconductor device to be included on a chip. Then, an ion implantation, with a dopant such as F, can be selectively performed to achieve proper Vt for other semiconductor devices on the chip.
