  • Publication number: 20200043704
    Abstract: Embodiments of the present disclosure relate to apparatus for improving quality of films deposited on a substrate by a CVD process. More specifically, a branched gas feed assembly uniformly distributes a process gas entering an annular plenum. Each conduit of a first plurality of conduits having substantially equal flow conductance is in fluid communication with one or more conduits of a second plurality of conduits having substantially equal flow conductance. Each conduit of the second plurality of conduits terminates at one of a plurality of outlets. Each outlet of the plurality of outlets is in fluid communication with one or more inlet ports of a plurality of inlet ports formed in the annular plenum. Each inlet port of the plurality of inlet ports is spaced equidistant about a central axis of the annular plenum.

  • Patent number: 10269614
    Abstract: Implementations of the present disclosure generally relate to a susceptor for thermal processing of semiconductor substrates. In one implementation, the susceptor includes a first rim surrounding and coupled to an inner region, and a second rim disposed between the inner rim and the first rim. The second rim includes an angled support surface having a plurality of cut-outs formed therein, and the angled support surface is inclined with respect to a top surface of the inner region.

  • Publication number: 20170175265
    Abstract: In one embodiment, a susceptor is provided and includes a first major surface opposing a second major surface, and a plurality of contact structures disposed on the first major surface, each of the contact structures being at least partially surrounded by one or more of a plurality of radially oriented grooves and an annular groove, wherein each of the plurality of contact structures includes a substrate contact surface, each of the substrate contact surfaces is between two parallel planes separated by a distance of 0.1 millimeters, and the substrate contact surfaces define a substrate receiving surface.

  • Publication number: 20030090039
    Abstract: A single pass, continuous, automated system for producing a pharmaceutical granulation includes multiple feeders to feed powders and liquids, a twin screw processor to granulate, a radio frequency or microwave based drying apparatus to dry the granulation, and at least one mill to process the dried granulation to desired particle sizes. The system incorporates means for monitoring key process parameters on-line, all of which are controlled by a controller provided with feedback at each component of the system. The granulation produced can be compressed into a tablet or incorporated into a capsule, both having a uniform distribution of the active ingredient. The system produces product having consistent properties even when production is scaled up for manufacture of the tablet in commercial volume.

  • Patent number: 5698562
    Abstract: This invention is directed to an aqueous pharmaceutical composition with 1.25 mg to about 10 mg trimethoprim per mL (wt/vol) of solution and a compound of suitable acid strength to permit the dissolving of trimethoprim at the appropriate concentration, with the composition having a pH of less than 6.0. This composition is particularly useful for pediatric oral use.
