Title: Spin-coating device for thin film formation, semiconductor device and formation of thin film
Inventor: HIRASAWA SHIGEKI
IPC: B05C5/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a flat thin film on a substrate having a roughened pattern on the surface at a high production efficiency. SOLUTION: A small amount of a coating material is dripped on a semiconductor wafer 1 while the wafer 1 is rotated and the dripped coating material is extended into a thin film shape by the centrifugal force of the wafer 1. A solvent in the coating material 10 is attracted from an exhaust pump 8 early in an evaporation process of the solvent to increase the evaporation rate of the solvent and a roughness, which corresponds to that of the surface of the wafer 1, is generated on the surface of the material 10. By forming the roughness on the surface of the material 10, the material 10 becomes liable to be fludized.  After an elapse of a prescribed time, when the attraction of the solvent from the pump 8 is stopped to decrease the evaporation rate of the solvent, the surface of a thin film consisting of the material 10 is rapidly flattened because the material 10 becomes liable to be fludized and the roughly flat thin film is formed by making the material 10 dry and dense.

Title: Heat transfer tube for heat exchanger
Inventor: TSUBOI TAKAYOSHI
IPC: F28F19/06
Filed: 1989-11-10
Abstract: PURPOSE:To obtain corrosion preventive effect for a long period by forming a conductive resin film containing iron as a main ingredient on the inner surface of a tube body and at least a specific base potential difference for copper oxide. CONSTITUTION:A heat transfer tube for a heat exchanger has a tube body made of copper or copper alloy and a conductive resin film formed on the inner surface of the body, containing iron as a main ingredient and having 0.1OMEGAcm or lower of volume resistivity, and the potential difference of the film to a copper oxide generated at the body is base potential of 0.25V or higher. Sea water is fed into the tube. If the film is a base potential of less than 0.25V to metal skin, corrosion preventive effect by sacrificial anode is small, and the metal skin is corroded. Accordingly, it is necessary that the potential difference to the metal skin of the film is 0.25V or higher. Even after conductive resin containing iron of initial composition as a main ingredient is eliminated, the inner surface of the body is covered with the film containing iron hydroxide as a main ingredient to prevent corrosion. The volume resistivity of the film is set to 0.1OMEGAcm or lower, thereby avoiding expansion of organic resin.
