  • Publication number: 20240128341
    Abstract: The disclosure provides a semiconductor structure and a method of forming the same. The semiconductor structure includes a base pattern including a channel region and a drain region, a first semiconductor layer on the channel region of the base pattern, and a gate structure on the first semiconductor layer. The gate structure includes a first stack disposed on the first semiconductor layer and a second stack disposed on the first stack. The first stack includes a first sidewall adjacent to the drain region and a second sidewall opposite to the first sidewall in a first direction parallel to a top surface of the base pattern. The first sidewall is at a first distance from the second stack in the first direction, and the second sidewall is at a second distance from the second stack in the first direction. The first distance is greater than the second distance.

  • Patent number: 11955441
    Abstract: An interconnect structure comprises a first dielectric layer, a first metal layer, a second dielectric layer, a metal via, and a second metal layer. The first dielectric layer is over a substrate. The first metal layer is over the first dielectric layer. The first metal layer comprises a first portion and a second portion spaced apart from the first portion. The second dielectric layer is over the first metal layer. The metal via has an upper portion in the second dielectric layer, a middle portion between the first and second portions of the first metal layer, and a lower portion in the first dielectric layer. The second metal layer is over the metal via. From a top view the second metal layer comprises a metal line having longitudinal sides respectively set back from opposite sides of the first portion of the first metal layer.
