  • Publication number: 20230298336
    Abstract: Disclosed are various systems and techniques for performing video-based surgeon technical-skill assessments and classifications. In one aspect, a process for classifying a surgeon's technical skill in performing a surgery is disclosed. During operation, the process receives a tool-motion track comprising a sequence of detected tool motions of a surgeon performing a surgery with a surgical tool. The process then generates a sequence of multi-channel feature matrices to mathematically represent the tool-motion track. Next, the process performs a one-dimensional (1D) convolution operation on the sequence of multi-channel feature matrices to generate a sequence of context-aware multi-channel feature representations of the tool-motion track.

  • Publication number: 20230282701
    Abstract: Techniques are provided herein to form semiconductor devices having gate cut structures. Adjacent semiconductor devices having semiconductor regions (e.g., fins or nanoribbons) extending in a first direction have a gate structure that extends over the semiconductor regions in a second direction and are separated by a gate cut structure extending in the first direction and interrupting the gate structure. The gate cut structure further extends between adjacent source or drain regions (corresponding to the adjacent semiconductor devices). A dielectric liner on at least a sidewall and/or top surface of the source or drain regions and also extends up a sidewall surface of the gate cut structure. In some cases, the gate structure includes a gate dielectric present on the semiconductor regions, but not present on the gate cut structure. A contact may pass through the liner and at least partially land on a source or drain region.

  • Publication number: 20230282718
    Abstract: Techniques are provided herein to form semiconductor devices having different pitches, yet maintaining a substantially similar depth to the diffusion regions between the semiconductor regions. In an example, a row of semiconductor devices having semiconductor regions extending in a first direction can include some devices having a diffusion region with a first width in the first direction and some devices having a diffusion region with a second width in the first direction, where the second width is different from the first width. The depths of the diffusion regions having both the first and second widths may be substantially similar (e.g., within 2 nm or less of one another). In some examples, the bottom surface of at least one of the wider diffusion regions has a step profile.

  • Publication number: 20230275124
    Abstract: Techniques are provided herein to form semiconductor devices having epitaxial diffusion regions (e.g., source and/or drain regions) wrapped by a conductive contact. In an example, a semiconductor device includes a source or drain region and a conductive layer that extends around the source or drain region such that the conductive layer at least contacts the sidewalls of the source or drain region or wraps completely around the source or drain region. In some examples, a conducive contact extends upward through a thickness of an adjacent dielectric layer and contacts the conductive layer from below, thus forming a backside contact. By forming a conductive layer around multiple sides of the source or drain region (rather than just contacting a top or bottom surface) more surface area of the source or drain region is contacted thus providing an improved ohmic contact and a lower overall contact resistance.

  • Publication number: 20230209798
    Abstract: Integrated circuit (IC) static random-access memory (SRAM) bit-cell structures comprising pass-gate transistors having a different number of active channel regions than the number of active channel regions in pull-down transistors. A pass-gate transistor with fewer active channel regions than a pull-down transistor may reduce read instability of an SRAM bit-cell, and/or reduce overhead associated with read assist circuitry coupled to the bit-cell. In some examples, one or more pass-gate transistor channel regions are impurity doped or removed from either a top side or bottom side of the pass-gate transistors to depopulate the number of active channel regions relative to a pull-down transistor.
