Abstract:
A semiconductor device includes a substrate and an insulating layer formed on the substrate. A first device may be formed on the insulating layer. The first device may include a first fin formed on the insulating layer, a first dielectric layer formed on the first fin, and a partially silicided gate formed over a portion of the first fin and the first dielectric layer. A second device also may be formed on the insulating layer. The second device may include a second fin formed on the insulating layer, a second dielectric layer formed on the second fin, and a fully silicided gate formed over a portion of the second fin and the second dielectric layer.
Abstract:
A semiconductor device includes an N-channel device and a P-channel device. The N-channel device includes a first source region, a first drain region, a first fin structure, and a gate. The P-channel device includes a second source region, a second drain region, a second fin structure, and the gate. The second source region, the second drain region, and the second fin structure are separated from the first source region, the first drain region, and the first fin structure by an insulating layer.
Abstract:
A FinFET-type semiconductor device includes a fin structure on which a relatively thin amorphous silicon layer and then an undoped polysilicon layer is formed. The semiconductor device may be planarized using a chemical mechanical polishing (CMP) in which the amorphous silicon layer acts as a stop layer to prevent damage to the fin structure.
Abstract:
A semiconductor device may include a substrate and an insulating layer formed on the substrate. A first device may be formed on the insulating layer, including a first fin. The first fin may be formed on the insulating layer and may have a first fin aspect ratio. A second device may be formed on the insulating layer, including a second fin. The second fin may be formed on the insulating layer and may have a second fin aspect ratio different from the first fin aspect ratio.
Abstract:
A method forms fin structures for a semiconductor device. The method includes forming a first fin structure including a dielectric material and including a first side surface and a second side surface; forming a second fin structure adjacent the first side surface of the first fin structure; and forming a third fin structure adjacent the second side surface of the first fin structure. The second fin structure and the third fin structure are formed of a different material than the first fin structure.

A double-gate semiconductor device includes a substrate, an insulating layer, a fin and a gate. The insulating layer is formed on the substrate and the gate is formed on the insulating layer. The fin has a number of side surfaces, a top surface and a bottom surface. The bottom surface and at least a portion of the side surfaces of the fin are surrounded by the gate.

Abstract:
For fabricating a field effect transistor within an active device area of a semiconductor substrate, a layer of gate dielectric material is deposited on the semiconductor substrate. A layer of gate electrode material is deposited on the layer of gate dielectric material, and the gate electrode material is a semiconductor material. At least one of an N-type dopant or a P-type dopant or a neutral dopant is implanted into the layer of gate electrode material such that the at least one of an N-type dopant or a P-type dopant or a neutral dopant has a dopant concentration in the layer of gate electrode material. A layer of photo-resist material, a layer of BARC (bottom anti-reflective coating) material, and the layer of gate electrode material are patterned to form a gate structure of the field effect transistor. The gate structure is comprised of the remaining gate electrode material, and the BARC (bottom anti-reflective coating) material remains on the gate structure. The BARC (bottom anti-reflective coating) material is then stripped from the gate structure using an etching reactant that etches both of the BARC (bottom anti-reflective coating) material and the gate electrode material. An etch rate of the gate electrode material in the etching reactant increases with an increase of the dopant concentration of the at least one of an N-type dopant or a P-type dopant or a neutral dopant within the gate electrode material. Sidewalls of the gate structure are trimmed by a trim length during the step of stripping the BARC (bottom anti-reflective coating) material from the gate structure. Thus, the dopant concentration of the at least one of an N-type dopant or a P-type dopant or a neutral dopant in the gate electrode material is adjusted to control the trim length of the gate structure.
Abstract:
Data replication includes generating replication data that is part of a replicated file system to be sent over a communication channel to a destination replication device; adding additional verification information to at least a portion of the replication data to prevent data corruption; and sending the replication data and the additional verification information over the communication channel to the destination replication device. The replication data with additional verification information is sent over the communication channel using a reliable protocol that allows the replication data to be verified by the reliable protocol at the destination replication device. The reliable protocol is a protocol capable of detecting most but not all data corruption introduced by the communication channel. The additional verification information includes information for verifying that replication data sent using the reliable protocol does not include data corruption that was introduced by the communication channel and undetected by the reliable protocol.
