  • Publication number: 20240379471
    Abstract: A diaphragm position of a valve may be detected and/or determined such that operation of the diaphragm may be monitored. A sensor included in the valve may generate sensor data that may be used to monitor the position of the diaphragm, which in turn may be used to determine a flow of a fluid through the valve. In this way, the sensor may be used to determine whether the diaphragm is properly functioning, may be used to identify and detect failures of the diaphragm, and/or may be used to quickly terminate operation of an associated deposition tool. This may reduce semiconductor substrate scrap, may reduce device failures on semiconductor substrates that are processed by the deposition tool, may increase semiconductor processing quality of the deposition tool, and/or may increase semiconductor processing yields of the deposition tool.

  • Publication number: 20240347363
    Abstract: The present disclosure relates to systems and methods for reducing the humidity within a FOUP (Front Opening Unified Pod) when loaded on an EFEM (Equipment Front End Module) for transfer of a semiconductor wafer substrate during fabrication processes. A deflector of specified structure is placed inside the EFEM above the load port of the FOUP. The deflector directs airflow in the EFEM away from the load port. The deflector includes a body with a plurality of apertures in the deflector body, and with a sloped front surface. Thus, the degree of penetration of high-humidity air from the EFEM into the FOUP is reduced.

  • Patent number: 12068277
    Abstract: A first semiconductor device and a second semiconductor device may be directly bonded using heterogeneous bonding layers. A first bonding layer may be formed on the first semiconductor device and the second bonding layer may be formed on the second semiconductor device. The first bonding layer may include a higher concentration of hydroxy-containing silicon relative to the second bonding layer. The second bonding layer may include silicon with a higher concentration of nitrogen relative to the first bonding layer. An anneal may be performed to cause a dehydration reaction that results in decomposition of the hydroxy components of the first bonding layer, which forms silicon oxide bonds between the first bonding layer and the second bonding layer. The nitrogen in the second bonding layer increases the effectiveness of the dehydration reaction and the effectiveness and strength of the bond between the first bonding layer and the second bonding layer.
