  • Patent number: 9711382
    Abstract: Embodiments described herein generally relate to apparatus for processing substrates. The apparatus generally include a process chamber including a lamp housing containing lamps positioned adjacent to an optically transparent window. Lamps within the lamp housing provide radiant energy to a substrate positioned on the substrate support. Temperature control of the optically transparent window is facilitated using cooling channels within the lamp housing. The lamp housing is thermally coupled to the optically transparent window using compliant conductors. The compliant conductors maintain a uniform conduction length irrespective of machining tolerances of the optically transparent window and the lamp housing. The uniform conduction length promotes accurate temperature control. Because the length of the compliant conductors is uniform irrespective of machining tolerances of chamber components, the conduction length is the same for different process chambers.

    Abstract: A supporting base, including a supporting plate and holders, holds a sapphire substrate so that one substrate surface faces a hot plate and the other substrate surface faces a radiant heat absorbing plate mounted on the supporting plate. Radiant heat from the hot plate passes through the sapphire substrate and heats the radiant heat absorbing plate. The sapphire substrate is heated from both sides by air warmed by the hot plate and radiant heat absorbing plate, and therefore does not warp. When the temperature of the sapphire substrate has reached the necessary level, the supporting base delivers the sapphire substrate to the surface of the hot plate, then moves away while the sapphire substrate is held against the hot plate and a semiconductor fabrication process is carried out on the sapphire substrate.

  • Patent number: 7758340
    Abstract: A heating device provided with a cooling plate and a heating plate is formed in a low height, and floats a substrate above the cooling plate and the heating plate and moves the substrate horizontally between the cooling plate and the heating plate by the pressure of a gas. A heating device 2 includes a cooling plate 3 provided with flotation gas spouting ports 3a, and a heating plate provided with flotation gas spouting ports. The flotation gas spouting ports 3a and 3b are arranged along a wafer moving passage and are formed so as to spout the gas obliquely upward toward a first end of the wafer moving passage on the side of the cooling plate. A pushing member 51 is brought into contact with a back part of a wafer W with respect to a direction in which the wafer W is moved to move the wafer W in a direction toward the heating plate 6 opposite a direction in which the flotation gas is spouted.

  • Patent number: 7488920
    Abstract: The electric radiant heater (101) adapted to a cooking hob is attached to the cooking plate (2a) forming with it an air cavity (13) in which the extended heating resistor (105) is housed on an insulating base (104). A peripheral outer wall (3,6) of the heater defines said cavity (13) in which there is a thermal switch (107) positioned, having a bimetal sensor (107c) the compact body (107a) of which rests on a central area (104a) of the insulating base, and its metal heat-receiving base (107b) in a position facing a heating resistor segment (105a) and either very close to or above it making contact. The relative position of the bimetal sensor (107c) enables a switching point (SWC?,SWO?) of the electrical contact (109) to be set in correlation to the hotplate warning light temperature range (TU).
