  • Publication number: 20240387265
    Abstract: A method includes forming a dielectric layer over an epitaxial source/drain region. An opening is formed in the dielectric layer. The opening exposes a portion of the epitaxial source/drain region. A barrier layer is formed on a sidewall and a bottom of the opening. An oxidation process is performing on the sidewall and the bottom of the opening. The oxidation process transforms a portion of the barrier layer into an oxidized barrier layer and transforms a portion of the dielectric layer adjacent to the oxidized barrier layer into a liner layer. The oxidized barrier layer is removed. The opening is filled with a conductive material in a bottom-up manner. The conductive material is in physical contact with the liner layer.

    Abstract: An open-type probe of a vertical probe card includes a frame, an elastic member, and a pin. The frame has an operation slot and two lateral openings being in spatial communication with the operation slot. The elastic member is assembled to the frame and is located in the operation slot. The pin includes an inner segment assembled in the operation slot and a contacting segment that protrudes from an opening of the operation slot. The pin abuts against the elastic member through the inner segment so as to be electrically coupled to the frame. The elastic member and the inner segment are arranged between the two lateral openings. The contacting segment is configured to abut against a device under test, so that the contacting segment is moved toward the operation slot to press the elastic member for deforming the elastic member to generate an elastic force.

  • Publication number: 20240377436
    Abstract: A tunnel-type probe includes a tube, an elastic member, and a pin. The elastic member is assembled in the tube. The pin is movably disposed through the tube, and is electrically coupled to the tube by being connected to the elastic member. The pin has an inner segment, a contacting segment, and a limiting segment, the latter two of which are connected to two ends of the inner segment. The inner segment is arranged in the tube and is connected to the elastic member. The contacting segment and the limiting segment are respectively located at two opposite sides of the tube. When the tunnel probe abuts against a device under test (DUT) through the contacting segment, the pin is moved in a direction away from the DUT, such that the elastic member is deformed from being pressed by the pin so as to generate an elastic force.

  • Patent number: 12135611
    Abstract: A BIOS backup/recovery system includes a chassis housing a BIOS backup/recovery subsystem coupled to a primary and a secondary BIOS storage system. The BIOS backup/recovery subsystem begins initialization operations and determines whether the primary BIOS storage system includes customized MAC addresses. If so, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match the customized MAC addresses in the primary BIOS storage system and, if not, performs a BIOS backup operation that includes copying the customized MAC addresses in the primary BIOS storage system to the secondary BIOS storage system. If not, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match default MAC addresses in the primary BIOS storage system and, if not, performs a BIOS recovery operation that includes copying customized MAC addresses in the secondary BIOS storage system to the primary BIOS storage system.

  • Publication number: 20240365461
    Abstract: The present disclosure is directed to a modularized vessel droplet generator assembly (MGDVA) including a droplet generator assembly (DGA). Under a normal operation, the liquid fuel moves along an operation pathway extending through the DGA to eject or discharge the liquid fuel (e.g., liquid tin) from a nozzle of the DGA into a vacuum chamber. The liquid fuel in the vacuum chamber is then exposed to a laser generating an extreme ultra-violet (EUV) light. Under a service operation, the operation pathway is closed and a service pathway extending through the DGA is opened. A gas is introduced into the service pathway forming a gas-liquid interface between the gas and the liquid fuel. The gas-liquid interface is driven to an isolation valve directly adjacent to the DGA. In other words, the gas pushes back the liquid fuel to the isolation valve. Once the gas-liquid interface reaches the isolation valve, the isolation valve is closed isolating the DGA from the liquid fuel.

  • Publication number: 20240361701
    Abstract: A method of inspecting an extreme ultraviolet (EUV) radiation source includes, in an idle mode, inserting a borescope mounted on a fixture through a first opening into a chamber of the EUV radiation source. The borescope includes a connection cable attached at a first end to a camera. The EUV radiation source includes an excitation laser that generates a light beam that is configured to focus onto tin droplets to generate EUV radiation inside the chamber of the EUV radiation source. The method further includes extending the extendible section, in a direction toward the second opening of the EUV radiation source, to move the camera beyond the blocking shield, and acquiring one or more images from a region beyond the blocking shield. The method also includes analyzing the one or more acquired images to determine an amount of tin debris deposited inside the chamber of the EUV radiation source.
