  • Patent number: 12272573
    Abstract: 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.

  • Patent number: 12237196
    Abstract: A multiple transport carrier docking device may be capable of storing and/or staging a plurality of transport carriers in a chamber of the multiple transport carrier docking device, and may be capable of forming an air-tight seal around a transport carrier in the chamber. Semiconductor wafers in the transport carrier may be accessed by a wafer transport tool while the air-tight seal around the transport carrier prevents and/or reduces the likelihood that contaminants in the semiconductor fabrication facility will reach the semiconductor wafers. The air-tight seal around the transport carrier may reduce defects of the semiconductor wafers that might otherwise be caused by the contaminants, may increase manufacturing yield and quality in the semiconductor fabrication facility, and/or may permit the continued reduction in device and/or feature sizes of integrated circuits and/or semiconductor devices that are to be formed on semiconductor wafers.
