Abstract: PURPOSE:To improve the characteristics of a semiconductor device by setting the specified pressure in the inside of a reacting container, setting the specified distance between an introducing port and a substrate, energy imparted to exciting gas, forming exciting species, and decomposing raw material gas with said exciting species. CONSTITUTION:The tip part of a feeding pipe 10 of raw material gas such as silane introduced into a container 1. The raw material gas (a) is supplied into a part between an introducing port 9 and a substrate 4 through the pipe 10. The pressure in the container is kept at 10<-3>-10<-4>Torr. Microwave energy is imparted to H2 in a chamber 7. Thus hydrogen exciting species is formed. The formed exciting species is inserted into the container 1 through the introducing port 9. The raw material gas is decomposed, and a microcrystal semiconductor film is grown on the substrate 4. At this time when the pressure in the container 1 is higher than 10<-1>Torr, the microcrystal is not formed in the thin film that is grown on the substrate 4, but an amorphous state is obtained. When the pressure is lower than 10<-3>Torr, the raw material gas flows into the chamber 7 from the introducing port 9 in the reverse direction. Plasma is formed by microwaves (b), and high charged particles are produced. When the distance between the introducing port 9 and the substrate 4 is larger than 10cm, an amorphous state is formed. Therefore, the distance is made to be less than 10cm.
