IPC: H01L21/306
Filed: 1988-01-26
Abstract: PURPOSE:To obtain a metal pattern with fine line width, by a method wherein a metal or a metal oxide layer is over-etched by using a pattern of photoresist as a mask, a pattern with narrower line width is formed, said pattern is used as a mask and patterning is performed to form a pattern of negative type photoresist. CONSTITUTION:By over-etching an Al layer 3, the line width d2 of the Al layer 3 pattern is made narrower than the line width d1, of a photoresist 4 pattern. When far-ultraviolet rays are irradiated, only the part 2a shown in figure is exposed, and the resist 4 and the Al layer 3 are eliminated. Negative type photoresist 2, 2a is developed, the part 2 is eliminated, the lower side of an aperture becomes equal to the pattern width d2 of the Al layer 3, and the upper side d3 is narrower than d2. An Al metal 5 vapor-deposited on a semiconductor wafer 1 is subjected to lift-off, and the negative type photo resist 2 is solved by methyl ethylene ketone. Thus an Al metal pattern whose line width is nearly equal to d3 is obtained. Thereby a pattern with fine line width is realized.

Abstract: PURPOSE:To enable manufacturing a cladding tube with superior mechanical properties by forming a pure zirconium inner lining by a chemical vapor deposition method. CONSTITUTION:A cladding tube 26 made of a zirconium alloy which is to clad fuel pellets is set in a device, the inside of a vessel is held at a specific pressure by operation of a vacuum pump 33, and is heated upto the highest specific temperature and kept by a heater 32, as well. A ZrClAl4 34 is kept at a specific temperature through a pipeline inserted into the cladding tube 26, and, when an inert gas is made to flow out at a specific rate from a bomb 36, Zr in the ZrClAl4 34 is vapor-deposited on an inner wall and Cl2 gas flows out to the outside. A process ends by conducting a beta (or an alpha+beta) quenching process at the same time when the vapor-deposition is finished. In this way, nodular- corrosive resistivity is given, oxigen concentration is hard to increase and growing of crystal grains can be regulated. In this chemical vapor deposition device, vapor-depositing conditions are comparatively flexible and generation of coarse crystal grains can be avoided.
