  • Publication number: 20220308464
    Abstract: In a method of manufacturing a semiconductor device a semiconductor wafer is retrieved from a load port. The semiconductor wafer is transferred to a treatment device. In the treatment device, the surface of the semiconductor wafer is exposed to a directional stream of plasma wind to clean a particle from the surface of the semiconductor wafer. The stream of plasma wind is generated by an ambient plasma generator and is directed at an oblique angle with respect to a perpendicular plane to the surface of the semiconductor wafer for a predetermined plasma exposure time. After the cleaning, a photo resist layer is disposed on the semiconductor wafer.

  • Patent number: 11430671
    Abstract: A wafer cleaning module and a method for cleaning a wafer with the wafer cleaning module are disclosed. For example, the wafer cleaning module includes a wafer chuck to hold a wafer, an ozone source to provide ozone gas towards the wafer, and an ultraviolet (UV) lamp module to provide UV light. The UV lamp module includes a UV light source and a rotatable reflector around the UV light source. The rotatable reflector is movable to adjust an amount of UV light directed towards a surface of the wafer.

  • Patent number: 11079669
    Abstract: An extreme ultraviolet (EUV) mask is received. The EUV mask has an EUV pellicle disposed thereover. The EUV pellicle is coupled to the EUV mask at least in part via glue that is disposed on the EUV mask. The EUV pellicle is removed, thereby exposing the glue. A localized glue-removal process is performed by targeting a region of the EUV mask on which the glue is disposed. The localized glue-removal process is performed without affecting other regions of the EUV mask that do not have the glue disposed thereon. The localized glue-removal process may include injecting a cleaning chemical onto the glue and removing a waste chemical produced by the cleaning chemical and the glue. The localized glue-removal process may also include a plasma process that applies plasma to the glue. The localized glue-removal process may further include a laser process that shoots a focused laser beam at the glue.
