  • Patent number: 11525185
    Abstract: Methods and devices are provided wherein rotational gas-flow is generated by vortex generators to decontaminate dirty gas (e.g., gas contaminated by solid particles) in pumping lines of vacuum systems suitable for use at a semiconductor integrated circuit fabrication facility. The vacuum systems use filterless particle decontamination units wherein rotational gas-flow is applied to separate and trap solid particles from gas prior to the gas-flow entering a vacuum pump. Methods are also described whereby solid deposits along portions of pumping lines may be dislodged and removed and portions of pumping lines may be self-cleaning.

  • Publication number: 20220364234
    Abstract: A method of forming a metal oxide layer includes at least the following steps. A substrate is provided in a process chamber of a deposition apparatus, where the substrate has a target layer formed thereon. A first gas and a second gas are introduced into the process chamber through a shower head of the deposition apparatus, so as to form a metal oxide film on the target layer, where the shower head is coated with a hydrophobic film. A patterned photoresist layer is formed on the metal oxide film. The metal oxide film is patterned by using the patterned photoresist layer as a mask, so as to form a patterned metal oxide film. The target layer is patterned by using the patterned metal oxide film as a mask.

  • Patent number: 11219115
    Abstract: An extreme ultra-violet (EUV) lithography system includes an EUV source and EUV scanner. A droplet generator provides a droplet stream in the EUV source. A gas shield is configured to surround the droplet stream. When a laser reacts a droplet in the stream EUV radiation and ionized particles are produced. The gas shield can reduce contamination resulting from the ionized particles by conveying the ionized particles to a droplet catcher. Components of the EUV source may be biased with a voltage to repel or attract ionized particles to reduce contamination from the ionized particles.
