  • Publication number: 20240133510
    Abstract: In some examples, a mount includes a mounting plate. In some examples, the mounting plate includes mounting holes disposed in a rectangular pattern on the mounting plate to mount a device to the mounting plate. In some examples, the mount includes an adjustment mechanism disposed within a depression of the mounting plate. In some examples, the mount includes a coupler to couple the mounting plate to a support.

  • Patent number: 11955553
    Abstract: Embodiments disclosed herein relate to using an implantation process and a melting anneal process performed on a nanosecond scale to achieve a high surface concentration (surface pile up) dopant profile and a retrograde dopant profile simultaneously. In an embodiment, a method includes forming a source/drain structure in an active area on a substrate, the source/drain structure including a first region comprising germanium, implanting a first dopant into the first region of the source/drain structure to form an amorphous region in at least the first region of the source/drain structure, implanting a second dopant into the amorphous region containing the first dopant, and heating the source/drain structure to liquidize and convert at least the amorphous region into a crystalline region, the crystalline region containing the first dopant and the second dopant.

  • Publication number: 20240088225
    Abstract: A method includes forming a gate stack on a first portion of a semiconductor substrate, removing a second portion of the semiconductor substrate on a side of the gate stack to form a recess, growing a semiconductor region starting from the recess, implanting the semiconductor region with an impurity, and performing a melt anneal on the semiconductor region. At least a portion of the semiconductor region is molten during the melt anneal.

  • Publication number: 20220105160
    Abstract: The present invention relates generally to isolated to arginine deiminase (ADI) proteins that have reduced cross-reactivity with anti-ADI-PEG 20 antibodies as compared to ADI-PEG 20, but which can have functional characteristics comparable to or better than ADI-PEG 20, compositions comprising the ADI proteins, and related methods of treating arginine-dependent diseases or related diseases such as cancer.
