  • Patent number: 11946158
    Abstract: An apparatus for growing semiconductor wafers, in particular of silicon carbide, wherein a chamber houses a collection container and a support or susceptor arranged over the container. The support is formed by a frame surrounding an opening accommodating a plurality of arms and a seat. The frame has a first a second surface, opposite to each other, with the first surface of the frame facing the support. The arms are formed by cantilever bars extending from the frame into the opening, having a maximum height smaller than the frame, and having at the top a resting edge. The resting edges of the arms define a resting surface that is at a lower level than the second surface of the frame. The seat has a bottom formed by the resting surface.

  • Patent number: 11830724
    Abstract: Various embodiments provide an apparatus and method for fabricating a wafer, such as a SiC wafer. The apparatus includes a support having a plurality of arms for supporting a substrate. The arms allows for physical contact between the support and the substrate to be minimized. As a result, when the substrate is melted, surface tension between the arms and molten material is reduced, and the molten material will be less likely to cling to the support.

  • Patent number: 10475673
    Abstract: Various embodiments provide a reaction chamber including a support, a receptacle, and a sponge. The support includes a plurality of bars that are spaced from each other by a plurality of openings. Each of the bars has side surfaces that are slanted or tilted downward such that melted material may readily flow through the openings. The support is covered with a coating of silicon carbide to prevent materials from adhering to the support. The receptacle underlies the support and is configured to collect any melted material that is drained through the openings of the support. The sponge is positioned in the receptacle and under the support. The sponge is configured to absorb any melted material that is collected by the receptacle.
