  • Publication number: 20250151371
    Abstract: Techniques described herein include forming respective (different) types of metal silicide layers for p-type source/drain regions and n-type source/drain regions of nanostructure transistors of a semiconductor device in a selective manner that reduces process complexity. For example, a p-type metal silicide layer may be selectively formed over a p-type source/drain region (e.g., such that the p-type metal silicide layer is not formed over the n-type source/drain region) of a first nanostructure transistor, and an n-type metal silicide layer may be formed over the n-type source/drain region (which may be selective or non-selective) of a second nanostructure transistor. This provides a low Schottky barrier height between the p-type metal silicide layer and the p-type source/drain region, as well as a low Schottky barrier height between the n-type metal silicide layer and the n-type source/drain region. This reduces the contact resistance for both p-type source/drain regions and n-type source/drain regions.

  • Publication number: 20250141091
    Abstract: A signal sensing device includes a body and two signal sensing elements disposed in the body. An insulating layer is sandwiched between the two signal sensing elements. Each of the two signal sensing elements incudes a signal transmission section and a signal sensing section in electrical connection with the signal transmission section. The signal transmission sections are planar antennae parallel to each other and each having an antenna shape of meander-line type. The antenna shape of each transmission section has a vertical projection on a plane parallel to each signal transmission section. The vertical projections of the antenna shapes do not overlap completely. When a portion of the body forms a surrounding portion which surrounds a to-be-sensed target, a portion or an entirety of each signal sensing section is located on the surrounding portion.
