Abstract

PURPOSE:To stop coating solution from flying off from the peripheral part of a substrate so as not to adhere to the edge face or the rear of the substrate by a method wherein the substrate is rotated at a high speed as a contact is kept coming into contact with the edge face of the substrate. CONSTITUTION:An applicator nozzle 4 is positioned at the center of a substrate 1, and a prescribed amount of coating solution 5 such as adhesive wax is made to drip from the nozzle 4. At this point, a contact 7 such a Teflon thread is kept on standby by the side of the substrate 1. As the contact 7 is kept in contact with the edge face of the substrate 1, a rotary table 7 is rotated at a high speed in the direction indicated by arrow F through a spindle shaft 6. At this point, coating solution hardly adheres to the edge face or the rear of the substrate 1. By this setup, coating solution flying off from the peripheral part of a substrate can be prevented from adhering to the rear or the edge face of the substrate, so that the substrate can be improved in both quality and yield.

2. Description of the Related Art Conventionally, there has been a spin coating method as a typical method for coating a semiconductor substrate such as a silicon wafer or a mask substrate with a coating solution such as a photoresist or an adhesive wax. This spin coating method
As shown in FIG. 3, a coating solution 5 is applied by a coating nozzle 4 whose axis A is vertical to a semiconductor substrate (hereinafter, simply referred to as a substrate) 1 which is suction-fixed on a rotary table 2 by a wafer chuck 3 of a vacuum type or the like. Is dropped on the central portion 1a of the wafer 1,
This is a method in which the motor 7 is rotated at a high speed in the direction of the arrow F through the spindle shaft 6 to spread the solution by utilizing the centrifugal force that acts so as to obtain a coating layer 5a having a uniform thickness. The film thickness of the coating layer 5a at this time is determined by the solution concentration, the volatilization rate of the solvent, the spin rotation speed, etc., and the volatilization rate of the solvent is affected by the environmental temperature, humidity, the solution temperature, the temperature of the substrate 1, and the like.

However, in the conventional spin coating method as described above, the coating solution is ejected from the peripheral portion of the substrate 1 by the centrifugal force and is fixed to the end face and the back face of the substrate 1, for example, the wafer bonding step. There is a drawback in that the amount of post-polishing becomes uneven. As a measure for preventing such adhesion to the end surface or the back surface, for example, Japanese Patent Laid-Open No. 60-11
[0118] Japanese Laid-Open Patent Publication No. 11-118 proposes a method of spraying a fluid such as resist solvent or gas from the back surface of the substrate through a nozzle. However, this method cannot completely prevent the photoresist or adhesive wax on the peripheral portion of the surface, which is necessary, from being eluted.
