Abstract: A doped contact region having an opposite conductivity type as a bottom semiconductor layer is provided underneath a buried insulator layer in a bottom semiconductor layer. At least one conductive via structure extends from an interconnect-level metal line through a middle-of-line (MOL) dielectric layer, a shallow trench isolation structure in a top semiconductor layer, and a buried insulator layer and to the doped contact region. The doped contact region is biased at a voltage that is at or close to a peak voltage in the RF switch that removes minority charge carriers within the induced charge layer. The minority charge carriers are drained through the doped contact region and the at least one conductive via structure. Rapid discharge of mobile electrical charges in the induce charge layer reduces harmonic generation and signal distortion in the RF switch.

Abstract: Disclosed are embodiments of a lateral, extended drain, metal oxide semiconductor, field effect transistor (LEDMOSFET) having a high drain-to-body breakdown voltage. Discrete conductive field (CF) plates are adjacent to opposing sides of the drain drift region, each having an angled sidewall such that the area between the drain drift region and the CF plate has a continuously increasing width along the length of the drain drift region from the channel region to the drain region. The CF plates can comprise polysilicon or metal structures or dopant implant regions within the same semiconductor body as the drain drift region. The areas between the CF plates and the drain drift region can comprise tapered dielectric regions or, alternatively, tapered depletion regions within the same semiconductor body as the drain drift region. Also disclosed are embodiments of a method for forming an LEDMOSFET and embodiments of a silicon-controlled rectifier (SCR) incorporating such LEDMOSFETs.

Abstract: At least one conductive via structure is formed from an interconnect-level metal line through a middle-of-line (MOL) dielectric layer, a shallow trench isolation structure in a top semiconductor layer, and a buried insulator layer to a bottom semiconductor layer. The shallow trench isolation structure laterally abuts at least two field effect transistors that function as a radio frequency (RF) switch. The at least one conductive via structure and the at interconnect-level metal line may provide a low resistance electrical path from the induced charge layer in a bottom semiconductor layer to electrical ground, discharging the electrical charge in the induced charge layer. The discharge of the charge in the induced charge layer thus reduces capacitive coupling between the semiconductor devices and the bottom semiconductor layer, and thus secondary coupling between components electrically disconnected by the RF switch is reduced.
