  • Publication number: 20230400787
    Abstract: An apparatus for manufacturing semiconductors includes a power amplifier to power a laser, a catalyst disposed in the power amplifier, an inlet port, and an exhaust port. The inlet port introduces a mixing gas to an interior of the power amplifier during a cleaning operation so that the mixing gas contacts a surface of the catalyst having a build-up thereon. The mixing gas reacts with and removes the build-up by generating gaseous by-products. The exhaust port removes the gaseous by-products from the power amplifier.

  • Publication number: 20230273525
    Abstract: An extreme ultra violet (EUV) lithography method includes receiving an EUV light by a scanner from an EUV light source, the EUV light passing through an intermediate focus disposed in the scanner and at a junction of the EUV light source and the scanner; directing the EUV light by the scanner to a reticle in the scanner; and deflecting nanoparticles from the EUV light source away from the reticle by generating a gas flow using a gas jet disposed entirely in the scanner and proximate to an interface of the scanner and the intermediate focus such that the gas jet does not block the EUV light.

  • Patent number: 11720035
    Abstract: In order to prevent observed long-term energy decay of power amplifiers and correspondingly increase the lifespan of CO2 lasers employing them, a hydrogen-doped mixing gas is supplied from an external pipeline during operation or periodic maintenance in order to effectively remove solid contaminants that build-up over time on a surface of a catalyst disposed within the power amplifier.

  • Patent number: 11675272
    Abstract: Supersonic gas jets are provided near the immediate focus of a lithography apparatus in order to deflect tin debris generated by the lithography process away from a scanner side and towards a debris collection device. The gas jets can be positioned in a variety of useful orientations, with adjustable gas flow velocity and gas density in order to prevent up to nearly 100% of the tin debris from migrating to the reticle on the scanner side.

  • Publication number: 20190384269
    Abstract: A device and a method for analyzing a manufacturing apparatus are provided. The device includes a storing unit, a detecting unit, a calculating unit and a determining unit. The storing unit is for storing a supply amount of material. The detecting unit is for continuously detecting the manufacturing apparatus once the material is used during whole of a process to obtain a total usage. The calculating unit is for calculating a usage ratio of the total usage to the supply amount. The determining unit is for determining whether the manufacturing apparatus is operated in a usage trouble operation according to the usage ratio.
