Title: Method for forming seed
Inventor: AEBA TOSHIAKI
IPC: H01L21/265
Filed: 1991-10-29
Abstract: PURPOSE:To provide a method for forming a small seed, by which the planarization of the active region including the seed is possible, and the further the pollution of the film surface is little. CONSTITUTION:A recess having such a form that the bottom is wider than the opening is made in a quartz glass substrate 1 and an SiN film 3, and a polycrystalline film is formed in this recess, and then the greater part of the region 7 of the polycrystalline film, where ions are implanted, are made amorphous by implanting ions into the polycrystalline Si film, and the polycrystalline film region 6, where ions are not implanted, is left as a seed. Accordingly, ions are intercepted in the polycrystalline film region in the vicinity of the edge of the recess, so a part of the polycrystalline film is not made amorphous, thus the polycrystalline seed cab be left in the region made amorphous, and a minute seed can be made by a self-alignment process without using a resist.

Title: Mirror for emitted light and diffraction lattice
Inventor: TOMIMASU TAKIO
IPC: G01J3/18
Filed: 1989-11-27
Abstract: PURPOSE:To prevent adhesion of hydrocarbon, to suppress lowering of reflectivity and to reduce the stopping times of a beam line by mounting a temp. raising apparatus to raise the temp., during the use of a reflecting mirror and a diffraction lattice, to room temp. or higher. CONSTITUTION:A reflecting mirror 1 is constituted so that electric heaters 6 are provided on the respective surfaces thereof excepting a reflecting surface and operated by the supply of a current from a power supply 5 to raise the surface temp. of the mirror 1. As the power supply 5, a variable power supply is used in order to control the heat value of the heater 6. When the surface temp. of the mirror 1 or that of a diffraction lattice is raised, the adsorption probability of hydrocarbon lowers and the decomposition reaction on the surface part is reduced by emitted light. Therefore, the adhesion amount of hydrocarbon to the surface of the mirror is reduced and the lowering of reflecting efficiency and diffraction efficiency is suppressed and the regeneration timing of the surface of the mirror is delayed and the stopping times of a beam line can be reduced.
