  • Publication number: 20250079227
    Abstract: A wafer retaining device is provided. The wafer retaining device includes a platen configured to support a semiconductor wafer, and a retainer assembly. The retainer assembly includes a mounting member coupled to the platen, a lever, and a biasing member including a first end coupled to the lever and a second end coupled to the mounting member. The biasing member is configured to bias the lever to a closed position relative to the platen. The lever inhibits movement of the semiconductor wafer when the lever is in the closed position.

  • Publication number: 20240282543
    Abstract: An assembly present in an ion source for supporting an arc chamber upon a base plate includes a first arc support plate, a first screw, and a second screw. The first screw passes through a smooth through-hole in an arm of the first arc support plate and extends into a bore in the base plate. The second (or adjustable) screw passes through a threaded through-hole in an arm of the first arc support plate and engages an upper surface of the base plate itself, and can be used to change the altitude and angle of the first arc support plate relative to the base plate. This adjustment ability improves the beam quality of the ion source.

  • Publication number: 20240249906
    Abstract: An ion source head includes a curved liner that is configured to more closely and accurately repel, direct, or deflect ion species generated within an ion source cavity of an ion source container of an ion source head towards an ion beam opening that extends through the ion source container of the ion source head. This prevents or reduces the ion species from becoming trapped in the ion source cavity instead of exiting the ion source cavity through the ion beam opening that extends through the ion source container of the ion source head. The curved liner may be received by a curved structure of the ion source container of the ion source head. The ion source head may be utilized within an implanter tool to refine or process a solid target with the ion beam generated by the ion source head with the curved liner.
