    摘要: An improved SRAM and fabrication method are disclosed. The method comprises use of a nitride layer to encapsulate PFETs and logic NFETs, protecting the gates of those devices from oxygen exposure. NFETs that are used in the SRAM cells are exposed to oxygen during the anneal process, which alters the effective work function of the gate metal, such that the threshold voltage is increased, without the need for increasing the dopant concentration, which can adversely affect issues such as mismatch due to random dopant fluctuation, GIDL and junction leakage.

    摘要: The present invention relates to high performance three-dimensional (3D) field effect transistors (FETs). Specifically, a 3D semiconductor structure having a bottom surface oriented along one of a first set of equivalent crystal planes and multiple additional surfaces oriented along a second, different set of equivalent crystal planes can be used to form a high performance 3D FET with carrier channels oriented along the second, different set of equivalent crystal planes. More importantly, such a 3D semiconductor structure can be readily formed over the same substrate with an additional 3D semiconductor structure having a bottom surface and multiple additional surfaces all oriented along the first set of equivalent crystal planes. The additional 3D semiconductor structure can be used to form an additional 3D FET, which is complementary to the above-described 3D FET and has carrier channels oriented along the first set of equivalent crystal planes.

    摘要: A gate dielectric and a gate conductor layer are formed on sidewalls of at least one semiconductor fin. The gate conductor layer is patterned so that a gate electrode is formed on a first sidewall of a portion of the semiconductor fin, while a second sidewall on the opposite side of the first sidewall is not controlled by the gate electrode. A partially gated finFET, that is, a finFET with a gate electrode on the first sidewall and without a gate electrode on the second sidewall is thus formed. Conventional dual gate finFETs may be formed with the inventive partially gated finFETs on the same substrate to provide multiple finFETs having different on-current in the same circuit such as an SRAM circuit.

    摘要: A local interconnect is formed with a gate conductor line that has an exposed sidewall on an active area of a semiconductor substrate. The exposes sidewall comprises a silicon containing material that may form a silicide alloy upon silicidation. During a silicidation process, a gate conductor sidewall silicide alloy forms on the exposed sidewall of the gate conductor line and an active area silicide is formed on the active area. The two silicides are joined to provide an electrical connection between the active area and the gate conductor line. Multiple sidewalls may be exposed on the gate conductor line to make multiple connections to different active area silicides.

    摘要: Contact with a floating body of an FET in SOI may be formed in a portion of one of the two diffusions of the FET, wherein the portion of the diffusion (such as N−, for an NFET) which is “sacrificed” for making the contact is a portion of the diffusion which is not immediately adjacent (or under) the gate. This works well with linked body FETs, wherein the diffusion does not extend all the way to BOX, hence the linked body (such as P−) extends under the diffusion where the contact is being made. An example showing making contact for ground to two NFETs (PG and PD) of a 6T SRAM cell is shown.
