  • Publication number: 20240071913
    Abstract: An integrated circuit structure includes a first interconnect layer, and a second interconnect layer above the first interconnect layer. The first interconnect layer includes a first interconnect feature and a second interconnect feature. The second interconnect layer includes a third interconnect feature, a fourth interconnect feature, and a fifth interconnection feature. The third interconnect feature extends from an upper surface of the first interconnect feature to an upper surface of the second interconnect layer. In an example, the fourth interconnect feature extends from an upper surface of the second interconnect feature to below the upper surface of the second interconnect layer, and the fifth interconnect feature extends from an upper surface of the fourth interconnect feature to the upper surface of the second interconnect layer. Thus, a double-decked vertical stack of interconnect features is formed using the fourth interconnect feature within the second interconnect layer.

  • Publication number: 20230328947
    Abstract: Uniform layouts for SRAM and register file bit cells are described. In an example, an integrated circuit structure includes a six transistor (6T) static random access memory (SRAM) bit cell on a substrate. The 6T SRAM bit cell includes first and second active regions parallel along a first direction of the substrate. First, second, third and fourth gate lines are over the first and second active regions, the first, second, third and fourth gate lines parallel along a second direction of the substrate, the second direction perpendicular to the first direction.

  • Publication number: 20230084182
    Abstract: Techniques are provided herein to form semiconductor devices having a different number of semiconductor nanoribbons compared to other semiconductor devices on the same substrate. In one example, two different semiconductor devices of a given memory cell, such as a random access memory (RAM) cell, include a p-channel device and an n-channel device. More specifically, the p-channel device may be a GAA transistor with a first number of semiconductor nanoribbons while the n-channel device may be a GAA transistor with a second number of semiconductor nanoribbons that is greater than the first number of semiconductor nanoribbons. In some cases, the n-channel device(s) have one additional semiconductor nanoribbon compared to the p-channel device(s). Depending on when the nanoribbons are removed during the fabrication process, different structural outcomes will occur that can be detected in the final device.

  • Publication number: 20230079586
    Abstract: Techniques are provided herein to form semiconductor devices having thinned semiconductor regions (e.g., thinner nanoribbons) compared to other semiconductor devices on the same substrate and at a comparable height (e.g., within same layer or adjacent layers). In an example, neighboring semiconductor devices of a given memory cell include a p-channel device and an n-channel device. The p-channel device may be a GAA transistor with a semiconductor nanoribbon having a first width while the n-channel device may be a GAA transistor with a semiconductor nanoribbon having a second width that is larger than the first width (e.g., first width is half the second width). The p-channel device may have a thinner width than the corresponding n-channel device in order to structurally lower the operating current through the p-channel devices by decreasing the width of the active semiconductor channel.
