  • Publication number: 20240379428
    Abstract: A method includes forming a patterned mask comprising a first opening, plating a conductive feature in the first opening, depositing a passivation layer on a sidewall and a top surface of the conductive feature, and patterning the passivation layer to form a second opening in the passivation layer. The passivation layer has sidewalls facing the second opening. A planarization layer is dispensed on the passivation layer. The planarization layer is patterned to form a third opening. After the planarization layer is patterned, a portion of the planarization layer is located in the second opening and covers the sidewalls of the passivation layer. An Under-Bump Metallurgy (UBM) is formed to extend into the third opening.

  • 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.

  • Publication number: 20240365460
    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.
