摘要： A susceptor having the most basic structure has a three-layer structure including a first and a second transparent quartz part and an opaque quartz part sandwiched therebetween. For example, the opaque quartz part is made of “foamed quartz”. In addition, the opacity of the opaque quartz part to flash light is determined to fall within an appropriate range based on the material or thickness of the opaque quartz part, taking into consideration the composition or thickness of a thin film formed on the substrate and various conditions concerning the energy of the irradiation light during flash light irradiation or the like. The stack structure may be composed of a stack of a plurality of opaque quartz layers having different opacities.

摘要： A phase shift photomask is constructed by forming a phase shifter defining a second light transmissive region on a substrate transmissive to exposure light. Exposure light undergoes multiple reflection within the phase shifter. This enables use of a thinner shifter film, minimizes a phase variation relative to a film thickness variation, and alleviates optical restraints on the film.

摘要： A powder feed apparatus and a control method thereof for a powder molding press wherein in feeding powder from a hopper of the powder feed apparatus to a feeder slidably disposed on a die plate of the press proper and charging powder into a die in the die plate the feeder is electronically controlled to a correct position on the die. Powder is fed from a powder feed apparatus into a feeder slidably disposed on a die plate of a press proper and a feeder drive motor is servo-controlled by an output obtained by comparing detection outputs from a position detector for detecting the vertical position of the die plate of the press proper and a position detector for detecting the position of the feeder in its sliding direction. As a result, it is possible to avoid the trouble of changing cams or inserting insert cams every time the shape of the compact being molded changes and it is possible to easily make changes to the movement speed of the feeder in correspondence with changes to the compact.
