摘要:
A high-temperature tube furnace comprises: a process tube (1) with a top cover (101) arranged on the top end thereof, the top cover (101) being provided with through holes (1011); a gas supply pipe (2) communicating with the through holes (1011) of the top cover (101) of the process tube (1), process gas being introduced into the process tube (1) through the gas supply pipe (2) and the through holes (1011) of the top cover (101) of the process tube (1); a wafer boat (3) arranged in the process tube (1), and comprising a supporting frame (301) and supporting plates (302), the supporting plates (302) being distributed in multiple layers along the length direction of the supporting frame (301) and used for supporting multiple substrates (w), each substrate (w) being placed on one supporting plate and each supporting plate supporting the entire bottom of the substrate (w). The multiple layers of supporting plates (302) are provided, and each supporting plate (302) supports the entire bottom of a substrate (w), thus avoiding defects of lattices in the substrates (w) caused by downward deformation of the substrates (w) during a high temperature process of 1200°C or above, and improving the yield of chips.

The disclosure describes continuous vacuum processing of a fiber tow. Continuous vacuum processing includes passing a fiber tow through a plurality of vacuum chambers and operating at least two vacuum chambers of the plurality of vacuum chambers at a different level of vacuum pressure than each other.
摘要:
Frames (112) and methods are provided for coating a reinforcing fiber (104, 106') of a composite component (100). The frame (112) includes a first frame end (118A) having a first cross-sectional shape, the first cross-sectional shape including one or more contact locations (124), the reinforcing fiber (104, 106') contacting the first frame end (118A) at the one or more contact locations (124), wherein a ratio of a length of the reinforcing fiber (104, 106') within a minimum distance from the frame (112) to the minimum distance is within a range of 0.2 to 20.
摘要:
A deposition support apparatus (20) and method (100) for coating a component (10), the deposition support apparatus (20) including a mask container (22) defining an interior (30) and having an opening (34) providing access to the interior (30). A barrier plate (36) with a component aperture (38) wherein the component (10) extends through the component aperture (38) with a first portion (54) of the component (10) located within the interior (30) and a second portion (56) of the component (10) extending above the at least one barrier plate (36).
摘要:
A vessel processing system for coating of a vessel is provided, the system comprising: a first processing station configured for performing a first processing of an interior surface of the vessel, a second processing station spaced from the first processing station and configured for performing a second processing of the interior surface of the vessel, a vessel holder comprising a vessel port configured to receive and seat an opening of the vessel for processing the interior surface of the seated vessel via the vessel port at the first processing station and at the second processing station, and a conveyor arrangement for transporting the vessel holder and the seated vessel after the first processing from the first processing station to the second processing station for the second processing of the interior surface of the seated vessel at the second processing station.
