  • Patent number: 11916110
    Abstract: Embodiments of the present disclosure provide a method for forming semiconductor device structures. The method includes forming a fin structure having a stack of semiconductor layers comprising first semiconductor layers and second semiconductor layers alternatingly arranged, forming a sacrificial gate structure over a portion of the fin structure, removing the first and second semiconductor layers in a source/drain region of the fin structure that is not covered by the sacrificial gate structure, forming an epitaxial source/drain feature in the source/drain region, removing portions of the sacrificial gate structure to expose the first and second semiconductor layers, removing portions of the second semiconductor layers so that at least one second semiconductor layer has a width less than a width of each of the first semiconductor layers, forming a conformal gate dielectric layer on exposed first and second semiconductor layers, and forming a gate electrode layer on the conformal gate dielectric layer.

  • Patent number: 11913973
    Abstract: A cantilever probe card device and a focusing probe thereof are provided. The focusing probe includes a soldering segment, a testing segment, two outer elastic arms spaced apart from each other, and a focusing portion. The testing segment is spaced apart from the soldering segment along an arrangement direction, and has a needle tip, an outer edge, and an inner edge that is opposite to the outer edge. Each of the two outer elastic arms has two end portions respectively connected to the soldering segment and the inner edge of the testing segment. The focusing portion is connected to the inner edge and is located between the needle tip and the two outer elastic arms, and has a plurality of focusing points arranged on one side thereof away from the two outer elastic arms.
