  • Publication number: 20230151484
    Abstract: Systems and methods for reducing obstructions in an exhaust line of a sub-atmospheric chemical vapor deposition (SACVD) system are disclosed. Such obstruction may occur due to the reaction of a silicon precursor with ozone, which forms solid particles in the exhaust line. A catalytic apparatus is provided which catalyzes the decomposition of ozone (O3) to oxygen (O2). Due to the lower reactivity of O2, the formation of solid particles is reduced.

  • Publication number: 20230154778
    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.

  • Publication number: 20230065793
    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.

  • Publication number: 20220367297
    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: 20220285192
    Abstract: A closed gas circulation system may include a sealed plenum, circulation fans, and a fan filter unit (FFU) inlet to contain, filter, condition, and re-circulate a gas through a chamber of an interface tool. The gas provided to the chamber is maintained in a conditioned environment in the closed gas circulation system as opposed to introducing external air into the chamber through the FFU inlet. This enables precise control over the relative humidity and oxygen concentration of the gas used in the chamber, which reduces the oxidation of semiconductor wafers that are transferred through the chamber. The closed gas circulation system may also include an air-flow rectifier, a return vent, and one or more vacuum pumps to form a downflow of collimated gas in the chamber and to automatically control the feed-forward pressure and flow of gas through the chamber and the sealed plenum.
