Abstract: Susceptor plates are provided for high temperature (e.g., greater than 1000° C.) batch processing of silicon wafers. The susceptor plates are designed to accommodate one wafer each, and a plurality of loaded susceptor plates are vertically spaced apart in a susceptor plate holder during batch or furnace processing. The susceptor plates provide “full” support beneath the wafers, with openings of at most 20 mm in diameter in the support surface. Protrusions are also kept to a minimum. The susceptor plates thus prevent the wafers from sagging beyond the point of plastic deformation. The support surface is also ground or polished to remove protrusions beyond a prescribed height. For a given treatment temperature, the susceptor plates permit higher ramp rates without wafer plastic deformation or sticking to the susceptor plate. In one embodiment, the susceptor plates are pre-bent in a direction opposing the direction of sag.

Abstract: An apparatus providing uniform microwave processing of products especially those that are likely to absorb microwave energy such as meat and the like. The apparatus uses at least a pair of complimentary processing waveguides. The waveguides are offset along at least one axis thereof so that the energy coupled to the product when traveling through a first waveguide section is presented with a complimentary or mirror image of the field variation applied to the product when traveling in the second waveguide. Energy may be fed to the elongated waveguides through a broad open wall or a wall having narrow openings. Coupling values can therefore be adjusted to transfer a higher percentage of energy in the feeder waveguide as microwaves propagate but then are diminished by a previous coupling section.

Abstract: A substrate to be processed in a high temperature processing chamber is preheated to avoid the problems associated with thermal shock when the substrate is dropped onto a heated susceptor. Preheating is effected by holding the substrate over a susceptor maintained at or near the processing temperature until the temperature of the substrate approaches the processing temperature. Thus, wafer warping and breakage are greatly reduced, and wafer throughput is improved because of time saved in maintaining the susceptor at constant temperature without cool down and reheat periods.
