Publication number: 20250218834Abstract: 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: March 19, 2025Publication date: July 3, 2025Inventors: Ren-Hau Wu, Cheng-Kang Hu, Yi-Fam Shiu, Cheng-Lung Wu, Hsu-Shui Liu

Patent number: 12272573Abstract: A load port is capable of monitoring various environmental parameters associated with a transport carrier to minimize and/or prevent exposure of the semiconductor substrates therein to increased humidity, increased oxygen, increased vibration, and/or one or more other elevated environmental conditions that might otherwise contaminate the semiconductor substrates, damage the semiconductor substrates, and/or cause processing defects. For example, the load port may monitor the environmental parameters as indicators of a potential blockage of a diffuser of the transport carrier, and a relief valve may be used to divert a gas away from the transport carrier based on a determination that a diffuser blockage has occurred. In this way, the gas may be diverted through the relief valve and away from the transport carrier to prevent increased humidity, contaminants, and/or vibration from contaminating and/or damaging the semiconductor substrates.Type: GrantFiled: June 28, 2021Date of Patent: April 8, 2025Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yi-Fam Shiu, Ting-Yau Shiu, Cheng-Lung Wu, Yang-Ann Chu, Jiun-Rong Pai
