Patent JP-S6425538-A (JP)
Title: Wet treating apparatus
Inventor: OKADA TSUNEO
IPC: H01L21/306
Filed: 1987-07-22
Abstract: PURPOSE:To make it possible to suppress dispersion in etching amount, by forming liquid paths on a facing surface of a treating head, which faces a material to be treated in a radial embedded pattern, making treating liquid to flow through the liquid paths, and forming the stream layer of the treating liquid between the material to be treated and the treating head. CONSTITUTION:A wafer as a material to be treated is concentrically arranged on a sucking head 11 so that the surface to be treated faces upward. The wafer is sucked and held with the sucking force of a sucking port 13. The wafer is rotated with the sucking head 11. When etching liquid 2 as treating liquid is supplied into a liquid groove 5 through a feeding path 6 with a feeding circuit 7, the etching liquid 2 flows from the center of the upper surface of the wafer 1 to its peripheral part along the liquid groove 5. Therefore, an etching liquid layer is formed on the wafer 1. Since the liquid groove 5 is slanted so that the depth becomes gradually shallow toward the peripheral part, the flow speed of the etching liquid 2 becomes approximately equal from the center to the peripheral part. Since the wafer 1 is rotated with the sucking head 11, the etching liquid is brought into contact with the entire surface of the wafer 1.

Abstract: PURPOSE:To form a good circular spot on a disc recording face by compensating spread in the direction of a laser light emission angle of a semiconductor laser by the first cylindrical lens to make the light parallel and arranging the second cylindrical lens orthogonally to the first cylindrical lens to obtain a parallel luminous flux. CONSTITUTION:The direction of a larger light emission angle of a semiconductor laser 12 is defined as the X direction, and a cylindrical lens 13 having a positive power is arranged with the axial direction in the Y direction to compensate spread components in the X direction, and a luminous flux parallel with the Z direction is obtained. A cylindrical lens 14 having a positive power is arranged with the axial direction in the X direction to compensate spread components in the Y direction, and a luminous flux parallel with the optical axis is obtained. If f1sin theta1=f2sintheta2 is satisfied when focal lengths of lenses 13 and 14 are f1 and f2 and light emission angles in the X direction and the Y direction of the laser are theta1 and theta2, an intensity distribution 15 of the luminous flux from the lens 14 is symmetrical axially, and the good beam spot is obtained. Since two lenses are arranged orthogonally to each other merely, the cost is reduced.
