摘要: A read-only memory cell array has vertical MOS transistors formed on trench walls, and is programmed with a programming mask which covers only the areas at which a transistor is not to be produced. As a result, the word lines can be formed with minimum grid spacing and the risk of short-circuiting between adjacent word lines is eliminated by buried ploy stringers.

摘要: Thin layers are deposited on a substrate such as a silicon substrate in series of evacuatable chambers into each of which an inert gas is admitted. In the case of a reactive sputtering deposition, a reactive gas is also admitted. Contamination between neighboring chambers with the reactive gas is prevented, and the chambers are rapidly charged with new reactive gas to achieve a stable gas flow by providing an inlet system including a pair of shut-off valves, and a closable flow governor, the shut-off valves and the flow governor being actuated in synchronism.
