LIGHT IRRADIATION TYPE HEAT TREATMENT METHOD AND HEAT TREATMENT APPARATUS
An upper radiation thermometer is provided obliquely above a semiconductor wafer to be measured. The upper radiation thermometer includes a photovoltaic detector that produces an electromotive force when receiving light. The photovoltaic detector has both high-speed responsivity and good noise properties in a low-frequency range. The upper radiation thermometer does not require a mechanism for cooling because the photovoltaic detector is capable of obtaining sufficient sensitivity at room temperature without being cooled. There is no need to provide a light chopper and a differentiating circuit in the upper radiation thermometer. This allows the upper radiation thermometer to measure the front surface temperature of the semiconductor wafer with a simple configuration both during preheating by means of halogen lamps and during flash irradiation.
Apparatus for manufacturing semiconductor device
An apparatus for manufacturing a semiconductor device includes a base portion, a bonding stage arranged on the base portion and having a placement surface for placing a substrate; and one or more connecting members which connect the base portion and the bonding stage, wherein at least one of the one or more connecting members is a connecting plate that deflects following the expansion and contraction of the bonding stage in the plane direction caused by a temperature change.
Support plate for localized heating in thermal processing systems
Support plates for localized heating in thermal processing systems to uniformly heat workpieces are provided. In one example implementation, localized heating is achieved by modifying a heat transmittance of a support plate such that one or more portions of the support plate proximate the areas that cause cold spots transmit more heat than the rest of the support plate. For example, the one or more portions (e.g., areas proximate to one or more support pins) of the support plate have a higher heat transmittance (e.g., a higher optical transmission) than the rest of the support plate. In another example implementation, localized heating is achieved by heating a workpiece via a coherent light source through a transmissive support structure (e.g., one or more support pins, or a ring support) in addition to heating the workpiece globally by light from heat sources.
