  • Publication number: 20250391663
    Abstract: A method includes forming a first fin protruding from a substrate at a center region, and a second fin protruding from the substrate at an edge region, the first fin and second fin each including an epitaxial stack over a fin base and a hard mask layer over the epitaxial stack. A patterning material is deposited adjacent to and over each of the first fin and the second fin. Different etch process parameters are used to etch the first fin at the center region than the etch process parameters of the second fin at the edge region.

  • Patent number: 10879097
    Abstract: A modular pressing device capable of generating stage downward forces is provided. The modular pressing device comprises a non-exchangeable pressing module and an exchangeable pressing module. The non-exchangeable pressing module includes a first downward force generating unit. The exchangeable pressing module includes a second downward force generating unit. The first downward force generating unit applies a first downward force to at least one of a testing seat and an electronic device through the exchangeable pressing module. The second downward force generating unit applies a second downward force to the electronic device. Thereby, the modular pressing device is capable to generate two different downward forces to reduce the downward surge force. In addition, as the exchangeable pressing module is worn, the exchangeable pressing module can be replaced quickly such that the maintenance cost can be effectively reduced and the stability of the apparatus can be enhanced.

  • Patent number: 10488459
    Abstract: A device for pressing an electronic component with different downward forces includes a first downward-pressure generating device, a depressing head, a second downward-pressure generating device and a depressing piston. The first downward-pressure generating device has the depressing head to apply a first downward pressure to the test socket and a portion of the electronic component. The second downward-pressure generating device has the depressing piston to apply a second downward pressure downward to another portion on the electronic component, so that the electronic component can couple electrically with a plurality of probe of the test socket. Thereupon, at least two downward-pressure generating devices are included to provide at least two different downward pressures to the electronic component solely or simultaneously to the electronic component and the testing equipment, such that specific downward-pressure requirements by precision electronic components can be fulfilled.

  • Patent number: 6721854
    Abstract: An external controller performs a thorough analysis and prediction on true requests from an application to issue a look-ahead request to an HDD or other auxiliary storage. An HDC card is connected to an HDD device which stores data and has a cache memory. The HDC card, which controls the HDD device, includes an access request tracer for tracing a true access request made by an application program executed by a host directly from the application program, a speculation request determination section for determining a speculation request to be expected later based on the traced true access request, and an HDC for issuing the determined speculation request to the HDD device.
