摘要:
An apparatus for hydrophobic treatment of a semiconductor wafer comprises a tank in which HMDS liquid is stored, a process chamber in which the wafer is treated, and a unit for supplying HMDS liquid from the tank into the process chamber in an amount needed at any desired time. The process chamber can be decompressed by an ejector which is connected to the process chamber through an exhaust pipe. A mount on which the wafer is mounted is arranged in the process chamber and it includes a heater embedded therein. A ring surrounds the mount and two liquid receiving recesses are formed on the top of the ring. Two HMDS liquid supply pipes extend just above their corresponding liquid receiving recesses. HMDS in liquid phase is supplied into the process chamber and vaporized in it. The density of HMDS gas in the process chamber is controlled by adjusting the amount of HMDS liquid supplied.

A substrate is held on a spin chuck, and resist solution is supplied to the surface of the substrate at a plurality of positions spaced at predetermined intervals from a plurality of resist nozzles provided the bottom surface of a resist pipe provided over a first direction across the surface of the substrate. Thereafter, the substrate is oscillated or rotated, thereby making the resist solution on the substrate a thin coating film with a uniform thickness. In the coating apparatus and method, which are excellent in responsiveness to a degree of viscosity of coating solution, various kinds of treatment agents with a wide range of viscosity can be used, and mechanical accuracy such as the space between the nozzles and the substrate, accuracy of the nozzle size, and the like can be loosened.

In this developing method and apparatus, a concentration measuring unit 222 picks part of developing fluid in a blending tank 186 to measure the resist concentration by an absorption photometry and feeds the detected resist concentration to a control unit 240. The control unit 240 controls respective valves 210, 212, 216 of a TMAH concentrate solution 200, a solvent pipe 204 and a drain pipe 208 in a manner that the developing fluid in the blending tank 186 has a TMAH concentration corresponding to a measured resist-concentration value to accomplish a constant developing rate, performing component control of the developing fluid. The developing fluid transferred from the blending tank 186 to a supply tank 188 is fed to a developer nozzle DN in a developing section 126 through a developer pipe 224 owing to the drive of a pump 228. Accordingly, even if the developing fluid is reused in the developing process in multiple times, it is possible to make sure of the uniformity in development.
