摘要:
A heat treatment device includes: a processing container that accommodates a plurality of substrates to be subjected to heat treatment; a substrate holding member that holds the plurality of substrates; an induction heating coil that forms an induction magnetic field inside the processing container; a high frequency power supply that applies a high frequency electric power to the induction heating coil; a gas supply mechanism that supplies a processing gas to the inside of the processing container; an exhaust mechanism that exhausts the inside of the processing container; and an induction heating element provided between the induction heating coil and the substrate holding member to enclose the substrate holding member inside the treatment container. The induction heating element is heated by an induction electric current formed by the induction magnetic field, and the substrates are heated by radiation heat from the induction heating element. The flow of the inductive electric current to the substrate is blocked by the induction heating element.

An amorphous carbon film forming method is performed by using a parallel plate type plasma CVD apparatus in which an upper electrode and a lower electrode are installed within a processing chamber, and the method includes: disposing a substrate on the lower electrode; supplying carbon monoxide and an inert gas into the processing chamber; decomposing the carbon monoxide by applying a high frequency power to at least the upper electrode and generating plasma; and depositing amorphous carbon on the substrate. It is desirable that the upper electrode is a carbon electrode.

A virtual blackbody radiation system (10) includes a light-emitting unit (1) including an LED driven by a fixed current, a light-receiving unit (2) including a sapphire rod, and an optical unit (3) including lenses (31, 32) for converging light emitted by the light-emitting unit in a convergent light. A cylindrical member (41)included in the optical unit (3)can be moved along the optical axis by a servomotor (42) included in a focus adjusting unit (4) for positional adjustment. The focus of convergent light relative to the light-receiving unit (2) can be adjusted by moving the lens (32) disposed in the cylindrical member (41) along the optical axis relative to the light-receiving unit (2). The intensity of the convergent light on the light-receiving unit (2) can be adjusted to the intensity of predetermined blackbody radiation. Thus, the virtual blackbody radiation system (10) is able to obtain light of a desired intensity without changing the driving current for driving a light source; consequently, the life time of the light source can be extended and the stability of radiation can be improved.

摘要:
A semiconductor wafer is mounted on a susceptor disposed in a processing chamber, the wafer is heated at a temperature on the order of 1000° C. for annealing, and a gas is supplied from a gas supply device disposed opposite to the wafer. When raising the temperature of the wafer and/or when lowering the temperature of the wafer, intra-surface temperature difference is limited to a small value to suppress the occurrence of slips. A gas supply device is divided into sections corresponding to a central part and a peripheral part, respectively, of the wafer to supply the gas at different flow rates onto the central part and the peripheral part, respectively. When raising the temperature of the wafer, for example, a gas of a temperature higher (lower) than that of the wafer is supplied at a flow rate per unit area greater (lower) than that at which the gas is supplied to the peripheral part to the central part. When lowering the temperature of the wafer, for example, a gas of a temperature higher (lower) than that of the wafer is supplied at a flow rate per unit area lower (higher) than that at which the gas is supplied to the peripheral part to the central part.
