Publication number: 20230207359Abstract: A load port receives a wafer carrier. An equipment front end module (EFEM) transfers semiconductor wafers to and from the wafer carrier via an access opening of a housing of the EFEM, and also transfers wafers to and from a semiconductor processing or characterization tool. A gas flow device disposed inside the housing of the EFEM is connected to receive a low humidity gas having relative humidity of 10% or less, and is positioned to flow the received low humidity gas across the access opening. A saturated pressure layer of the gas flow device has a permeability for the low humidity gas that increases with increasing distance from a gas inlet edge of the saturated pressure layer, for example due to holes of varying diameter and/or density passing through the saturated pressure layer. A filter layer of the gas flow device uniformizes the gas exiting the saturated pressure layer.Type: ApplicationFiled: February 24, 2022Publication date: June 29, 2023Inventors: Ren-Hau Wu, Cheng-Kang Hu, Yi-Fam Shiu, Cheng-Lung Wu, Hsu-Shui Liu

Publication number: 20220317668Abstract: A cooling controller receives, from one or more sensors, wafer information associated with a wafer. The cooling controller determines a pattern mask area for the wafer based on the wafer information. The cooling controller determines a cooling time for the wafer based on the pattern mask area. The cooling controller causes a cooling plate to cool the wafer for a time duration equal to the cooling time. Determining the cooling time for a wafer based on a pattern mask area provides stable and consistent wafer temperatures for wafers having different mask and layout properties, which reduces mask overlay variation and increases wafer yield.Type: ApplicationFiled: March 31, 2021Publication date: October 6, 2022Inventors: Yung-Yao LEE, Cheng-Kang HU, Jui-Chun PENG, Hsu-Shui LIU
