    摘要: A semiconductor processing apparatus includes a load chamber, an unload chamber, a common transfer chamber, a first process chamber, and a second process chamber, which are connected via gate valves. The load and unload chambers are connected to a first vacuum-exhaust mechanism including a common dry pump. The common transfer chamber is connected to a second vacuum-exhaust mechanism including a dry pump. The first and second processes chambers are connected to a third vacuum-exhaust mechanism including a common dry pump, and first and second turbo molecular pumps. The processing apparatus includes a controller which can drive and stop the dry pumps independently of each other in coordination with open/closed switching of the gate valves, while keeping the turbo molecular pumps driven.

    摘要: RIE of metallization is achieved at low power and low pressure using Cl.sub.2 and HCl as reactant species by creating a transformer coupled plasma with power applied to electrodes positioned both above and below a substrate with metallization thereon to be etched. Three layer metallizations which include bulk aluminum or aluminum alloy sandwiched between barrier layers made from, for example, Ti/TiN, are etched in a three step process wherein relatively lower quantities of Cl.sub.2 are used in the plasma during etching of the barrier layers and relatively higher quantities of Cl.sub.2 are used during etching of the bulk aluminum or aluminum alloy layer. The ratio of etchants Cl.sub.2 and HCl and an inert gas, such as N.sub.2 are controlled in a manner such that a very thin side wall layer (10-100 .ANG.) of reaction byproducts created during RIE are deposited on the side walls of trenches formed in the metallization during etching. The side wall layer improves the isotropic nature of the etch such that submicron metallization lines with defect free side walls are formed. Hydrogen (H.sub.2) can be added to the plasma and will act to reduce corrosion.

    摘要: A dry etching method is disclosed for use in patterning a stacked film of a metal film containing aluminum as the base component and a thin film including at least one of titanium and titanium nitride. In this method, the thin film is dry-etched using a first etching gas (a mixture of CF4 gas, Ar gas and Cl gas) having a gas composition for preventing the metal film from being processed. The metal film is then dry-etched using a second etching gas (a mixture of Cl gas and BCl3 gas) having a gas composition other than the first etching gas.
