Abstract: A double-semiconductor device includes a substrate, an insulating layer, a fin and a gate. The insulating layer is formed on the substrate and the fin is formed on the insulating layer. The fin has a number of side surfaces, a top surface and a bottom surface. The gate is formed on the insulating layer and surrounds the top surface, bottom surface and the side surfaces of the fin in the channel region of the semiconductor device. Surrounding the fin with gate material results in an increased total channel width and more flexible device adjustment margins.

Abstract: A FinFET includes a fin formed on an insulating layer and a first gate material layer formed proximate to sides of the fin. The FinFET further includes a protective layer formed above the first gate material layer and the fin, and a second gate material layer formed above the protective layer and the fin. The second gate material layer may be formed into a gate for the fin that may be biased independently of gate(s) formed from the first gate material layer, thus providing additional design flexibility in controlling the potential in the fin during on/off switching of the FinFET.

Abstract: A method of manufacturing a MOSFET type semiconductor device includes planarizing a gate material layer that is deposited over a channel. The planarization is performed in a multi-step process that includes an initial “rough” planarization and then a “fine” planarization. The slurry used for the finer planarization may include added material that tends to adhere to low areas of the gate material.
