摘要: Disclosed is a method and structure for a fin-type field effect transistor (FinFET) structure that has different thickness gate dielectrics covering the fins extending from the substrate. These fins have a central channel region and source and drain regions on opposite sides of the channel region. The thicker gate dielectrics can comprise multiple layers of dielectric and the thinner gate dielectrics can comprise less layers of dielectric. A cap comprising a different material than the gate dielectrics can be positioned over the fins.

摘要: A method and structure for an integrated circuit structure that utilizes complementary fin-type field effect transistors (FinFETs) is disclosed. The invention has a first-type of FinFET which includes a first fin, and a second-type of FinFET which includes a second fin running parallel to the first fin. The invention also has an insulator fin positioned between the source/drain regions of the first first-type of FinFET and the second-type of FinFET. The insulator fin has approximately the same width dimensions as the first fin and the second fin, such that the spacing between the first-type of FinFET and the second-type of FinFET is approximately equal to the width of one fin. The invention also has a common gate formed over channel regions of the first-type of FinFET and the second-type of FinFET. The gate includes a first impurity doping region adjacent the first-type of FinFET and a second impurity doping region adjacent the second-type of FinFET. The differences between the first impurity doping region and the second impurity doping region provide the gate with different work functions related to differences between the first-type of FinFET and the second-type of FinFET. The first fin and the second fin have approximately the same width.

摘要: A field effect transistor (FET) has underlap regions adjacent to the channel doping region. The underlap regions have very low dopant concentrations of less than 1×1017/cc or 5×1016/cc and so tend to have a high resistance. The underlap regions reduce overlap capacitance and thereby increase switching speed. High resistance of the underlap regions is not problematic at subthreshold voltages because the channel doping region also has a high resistance at subthreshold voltages. Consequently, the present FET has low capacitance and high speed and is particularly well suited for operation in the subthreshold regime.

摘要: Structures and a method for detecting ionizing radiation using silicon-on-insulator (SOI) technology are disclosed. In one embodiment, the invention includes a substrate having a buried insulator layer formed over the substrate and an active layer formed over the buried insulator layer. Active layer may be fully depleted. A transistor is formed over the active layer, and includes a first gate conductor, a first gate dielectric and source/drain diffusion regions. The first gate conductor may include a material having a substantially (or fully) depleted doping concentration such that it has a resistivity higher than doped polysilicon such as intrinsic polysilicon. A second gate conductor is formed below the buried insulator layer and provides a second gate dielectric corresponding to the second gate conductor. A channel region between the first gate conductor and the second gate conductor is controlled by the second gate conductor (back gate) such that it acts as a radiation detector.

摘要: Disclosed are embodiments of a structure that comprises a first device, having multiple FETs, and a second device, having at least one FET. Sections of a first portion of a semiconductor layer below the first device are doped and contacted to form back gates. A second portion of the semiconductor layer below the second device remains un-doped and un-contacted and, thus, functions as an insulator. Despite the performance degradation of the first device due to back gate capacitance, the back gates result in a net gain for devices such as, SRAM cells, which require precise Vt control. Contrarily, despite marginal Vt control in the second device due to the absence of back gates, the lack of capacitance loading and the added insulation result in a net gain for high performance devices such as, logic circuits.
