  • Publication number: 20250180999
    Abstract: Fluid pressure flowing through first main line in pressure compensator using first pressure sensor is measured. Fluid flows along first main line through pressure compensator to semiconductor device processing apparatus, through apparatus, then through compensator via second main line. First pressure sensor is attached to first pressure sensor line branching off first main line. Fluid pressure flowing through second main line is measured using second pressure sensor. Second pressure sensor is attached to second pressure sensor line branching off second main line. Pressure difference between fluid flowing through first and second main lines is determined. Fluid flow rate is adjusted when difference is greater than threshold amount. A first tank is attached to one of first or second main lines via a conduit, and second tank is attached to first or second pressure sensor line when first tank is attached to corresponding first or second main line via a conduit.

  • Publication number: 20250109870
    Abstract: The present disclosure is at least directed to utilizing air curtain devices to form air curtains to separate and isolate areas in which respective workpieces are stored from a transfer compartment within a workpiece processing apparatus. The transfer compartment of the workpiece processing apparatus includes a robot configured to transfer or transport ones of the workpieces to and from these respective storage areas through the transfer compartment and to and from a tool compartment. A tool is present in the tool compartment for processing and refining the respective workpieces. Clean dry air (CDA) may be circulated through the respective storage areas. The air curtains formed by the air curtain devices and the circulation of CDA through the respective storage areas reduces the likelihood of the generation of defects, damages, and degradation of the workpieces when present within the workpiece processing apparatus.

  • Patent number: 12147541
    Abstract: Techniques for secure boot up of unified extensible firmware interface (UEFI) compliant devices are described. In an example, execution of a driver associated with a hardware component of a computing device may be detected during booting of the computing device. Based on the detection, a first driver hash of a system table of the UEFI may be computed, where the system table is a data structure that stores configuration details of the computing device and UEFI services. Thereafter, a second driver hash of the system table may be computed based on detection of completion of the execution of the driver. The first driver hash and the second driver hash may then be compared to determine tampering with the system table of the UEFI.
