  • Patent number: 10892147
    Abstract: Methods for matching semiconductor processing chambers using a calibrated spectrometer are disclosed. In one embodiment, plasma attributes are measured for a process in a reference chamber and a process in an aged chamber. Using a calibrated light source, an optical path equivalent to an optical path in a reference chamber and an optical path in an aged chamber can be compared by determining a correction factor. The correction factor is applied to adjust a measured intensity of plasma radiation through the optical path in the aged chamber. Comparing a measured intensity of plasma radiation in the reference chamber and the adjusted measured intensity in the aged chamber provide an indication of changed chamber conditions. A magnitude of change between the two intensities can be used to adjust the process parameters to yield a processed substrate from the aged chamber which matches that of the reference chamber.

  • Publication number: 20210005500
    Abstract: Embodiments of the present disclosure generally relate to a substrate processing chamber, and components thereof, for forming semiconductor devices. The processing chamber comprises a substrate support, and an edge ring is disposed around the substrate support. The edge ring comprises a material selected from the group consisting of quartz, silicon, cross-linked polystyrene and divinylbenzene, polyether ether ketone, Al2O3, and AlN. The material of the edge ring is selected to modulate the properties of hardmask films deposited on substrates in the processing chamber. As such, hardmask films having desired film properties can be deposited in the processing chamber without scaling up the RF power to the chamber.

  • Patent number: 10882160
    Abstract: A method of fabricating a polishing pad using an additive manufacturing system includes depositing a first set of successive layers onto a support by droplet ejection. Depositing the first set of successive layers includes dispensing a polishing pad precursor to first regions corresponding to partitions of the polishing pad and dispensing a sacrificial material to second regions corresponding to grooves of the polishing pad. A second set of successive layers is deposited by droplet ejection over the first set of successive layers. The second set of successive layers corresponds to a lower portion of the polishing pad. The first set of successive layer and the second set of successive layers provide a body. The body is removed from the support. Removing the sacrificial material from the body provides the polishing pad with a polishing surface that has the partitions separated by the grooves.

  • Patent number: 10886053
    Abstract: In large area plasma processing systems, process gases may be introduced to the chamber via the showerhead assembly which may be driven as an RF electrode. The gas feed tube, which is grounded, is electrically isolated from the showerhead. The gas feed tube may provide not only process gases, but also cleaning gases from a remote plasma source to the process chamber. The inside of the gas feed tube may remain at either a low RF field or a zero RF field to avoid premature gas breakdown within the gas feed tube that may lead to parasitic plasma formation between the gas source and the showerhead. By feeding the gas through an RF choke, the RF field and the processing gas may be introduced to the processing chamber through a common location and thus simplify the chamber design.

    Abstract: An FI having an in-situ particle detector and a method for particle detection therein are provided. In one aspect, the FI includes a fan, a substrate support, a particle detector, and an exhaust outlet. The fan, substrate support, and particle detector are arranged such that, in operation, the fan directs air towards the exhaust outlet and over a substrate on the substrate support to create laminar flow. The particle detector, positioned downstream from the substrate support and upstream from the exhaust outlet, analyzes the air and detects particle concentration before the particles are exhausted. The collected particle detection data may be combined with data from other sensors in the FI and used to identify the source of particle contamination. The particle detector may also be incorporated into other system components, including but not limited to, a load-lock or buffer chamber to detect particle concentration therein.
