Abstract: Disclosed herein is a semiconductor device that includes a semiconducting substrate and a work-function adjusting layer positioned at least partially in the semiconducting substrate, the work-function adjusting layer having a middle section, opposing ends and an end region located proximate each of said opposing ends and a gate electrode positioned above the work-function adjusting layer. Each of the end regions has a maximum thickness that is at least 25% greater than an average thickness of the middle section of the work-function adjusting layer.

Abstract: An electronic device includes first and second electronic device dice. The first electronic device die is embedded within a resin layer. A dielectric layer is located over the device die and the resin layer. First interconnects within the dielectric layer connect a first subset of electrical contacts on the first electronic device to corresponding terminals at a surface of the dielectric that are located over the first electronic device. Second interconnects within the dielectric layer connect a second subset of electrical contacts on the first electronic device to corresponding bump pads at a surface of the dielectric that are located over the resin layer.

Abstract: A parasitic PIN device in a BiCMOS process is disclosed. The device is formed on a silicon substrate, in which an active region is isolated by shallow trenches. The device includes: an N-type region, consisting of N-type pseudo buried layers respectively formed at the bottom of shallow trench isolation oxide layers and extending into the active region; an I-type region, consisting of an N-type collector implantation region formed in the active region and contacting with the N-type region; a P-type region, consisting of a P-doped intrinsic base epitaxial layer on a surface of the active region and contacting with the I-type region. The device of the present invention has a low insertion loss and a high isolation. A manufacturing method of parasitic PIN device in compatible with existing BiCMOS process is also disclosed.

Abstract: Transistor devices and methods of their fabrication are disclosed. In one method, a dummy gate structure is formed on a substrate. Bottom portions of the dummy gate structure are undercut. In addition, stair-shaped, raised source and drain regions are formed on the substrate and within at least one undercut formed by the undercutting. The dummy gate structure is removed and a replacement gate is formed on the substrate.
