Abstract: A chemical treating apparatus for performing a predetermined treatment of a principal surface of a substrate by delivering a treating solution thereto. The apparatus includes a treating solution delivery nozzle for delivering the treating solution to the principal surface of a substrate. The nozzle has a treating solution reservoir adjacent a tip end thereof for storing the treating solution. A temperature control device holds the treating solution reservoir to control the temperature of the treating solution in the treating solution reservoir through heat exchange with the treating solution.

Abstract: A heat-treating plate has three balls arranged on an upper surface thereof. Top ends of the balls slightly protrude from the upper surface of the heat-treating plate. A substrate is heated as placed on and supported by the balls of the heating plate such that a minute spacing called a proximity gap is formed between the lower surface of the substrate and the upper surface of the heating plate. The upper surface of the heat-treating plate has a high emissivity of 0.9 to 1.0 to heat the substrate efficiently and with high precision.

Abstract: A resin block has a treating solution channel extending between and opening at front and back surfaces thereof Heat conductive members are face-bonded to the front and back surfaces of the resin block, respectively, for closing the channel. Consequently, no air is present between the resin block and heat conduction members, thereby improving the efficiency of heat exchange. A nozzle of simple construction is realized only by face-bonding the two heat conductive members to the open front and rear surfaces of the resin block. Temperature control plates hold the heat conductive members along with the resin block to effect a temperature control, whereby the temperature of a treating solution in the treating solution channel is controlled effectively through the heat conductive members. The treating solution adjusted to a desired temperature is delivered from a discharge opening to a substrate for performing substrate treatment with high accuracy.
