  • Patent number: 11978751
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

  • Publication number: 20240096732
    Abstract: Some implementations described herein provide techniques and apparatuses for a fixture including a semiconductor die package and methods of formation. The semiconductor die package is mounted to an interposer. In addition to the semiconductor die package, the fixture includes a lid component having a top structure and footing structures that connect the lid component to the interposer. The fixture includes a thermal interface material between a top surface of the semiconductor die package and the top structure of the lid component. The footing structures, connected to the interposer using deposits of an epoxy material, provide increase a structural rigidity of the fixture relative to another fixture not including the footing structures.

  • Publication number: 20240071847
    Abstract: A semiconductor package including two different adhesives and a method of forming are provided. The semiconductor package may include a package component having a semiconductor die bonded to a substrate, a first adhesive over the substrate, a heat transfer layer on the package component, and a lid attached to the substrate by a second adhesive. The first adhesive may encircle the package component and the heat transfer layer. The lid may include a top portion on the heat transfer layer and the first adhesive, and a bottom portion attached to the substrate and encircling the first adhesive. A material of the second adhesive may be different from a material of the first adhesive.

  • Publication number: 20240071665
    Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

  • Publication number: 20090300849
    Abstract: The present invention relates to a method of extracting oil of cloth via supercritical fluid, comprises the steps of: a cloth to be extracted is provided in an extracting tank; a gas is filled into a storing tank; a water-cooling machine is provided and served to cool down the temperature of the gas; a pump is provided and served to compress the gas; a water-heating machine is provided and served to raise the temperature of the gas so the gas becomes a supercritical fluid; and the supercritical fluid is inserted into the extracting tank for extracting the oil. By the above mentioned method, the cleanness of the cleanroom wiping cloth can be immediately sensed and obtained, and the gas can be recycled for achieving energy-saving.
