Title:
SEMICONDUCTOR DEVICE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3300153
Kind Code:
B2
Abstract:

PURPOSE: To obtain a method for manufacturing a semiconductor element such as a thin-film transistor by crystallizing a silicon film in a substantially amorphous state by annealing it at a temperature lower than the temperature of crystallization of ordinary amorphous silicon or than a glass transition point of a substrate.
CONSTITUTION: A film, particles, a cluster or the like shaped in an island, a line, a stripe or a dot and having nickel, iron, cobalt, platinum or a siliside thereof, each sort of salt thereof or the like is formed selectively on the upper or lower side of an amorphous silicon film 1 and annealed at a temperature lower than the temperature of crystallization of ordinary amorphous silicon or than a glass transition point of a substrate. Starting from this, crystallization is made to advance and thereby a crystal silicon film 3 is obtained. By using this crystal silicon film 3, moreover, a semiconductor element such as a thin film transistor is formed.
