Title: Spin coating
Inventor: SHIN ARIAKE
IPC: G03F7/16
Filed: 1990-05-12
Abstract: PURPOSE:To make it possible to uniformly form a thick film on the whole surface of a square- shaped substrate by a method wherein an inclined surface making an acute angle against the coating surface of the substrate is formed on the outer circumference of the square-shaped substrate, and a spin coating is conducted thereon. CONSTITUTION:An inclined surface 13, which makes an inclination of an angle of (theta) against the coating surface of a square-shaped substrate 10, formed is on the outer circumference of the square-shaped substrate 10 is which rotated at high speed. Then, the above-mentioned square-shaped substrate 10 is mounted on the mount 23 provided in the center of a cylindrical main body 20. Subsequently, coating liquid is dripped on the surface of the square-shaped substrate 10, a rotating shaft 24 is rotated at high speed by driving a motor 25, and the square--shaped substrate 10 is rotated at high speed. At this time, as an inclined surface 13 is formed on the outer circumferential edge of the squareshaped substrate 10, the air stream F brought into collision with the inclined surface 13 is split into the upper and lower stream without disturbance even when the substrate is rotated at high speed, and no eddy stream is generated on the surface of the square-shaped substrate 10. As a result, the speed of the air stream on the surface 12 of the square-shaped substrate 10 generally becomes uniform on the whole surface, the substrate 10 is not subjected to the influence of an adverse effect due to the turbulence of air stream at the corners when a film is formed thereon, and the uniform film the same as in the center part can be formed.
