An apparatus treating substrates in a high-temperature and high-pressure atmosphere, the substrates being treated in a batch that includes one lot of the substrates treated as a unit. A supporting jig is provided with means to support a plurality of the substrates in a shelved arrangement, the supporting jig and substrates being configured to enter and exit from a treating chamber within a pressure vessel as a single unit. The supporting jig is surrounded by a casing. In order to cope with the difficulty of oxidization of the substrates, an oxygen getter is disposed in either the supporting jig or in the casing. The pressure vessel includes an opening whereby a reducing gas can be introduced into the treating chamber. Further, the pressure vessel and a stocking portion of the substrates are installed within a housing such that contamination is further reduced and control is made easier.

This invention provides a method of forming a metal wiring film excellent in EM resistance and low electric resistance. In a method of forming a wiring structure by filming and covering the surface of the insulating film of a substrate to be treated having a hole or groove formed thereon with a metallic material such as copper, aluminum, silver or the like, thereby filling the hole or groove inner part with the metallic material to form a wiring structure, the substrate to be treated is exposed to a high temperature under a high-pressure gas atmosphere after the continuous filming and covering with the metallic material along the inner surface profile of the hole or groove, whereby the surface diffusion phenomenon of the metallic material is promoted to reform the metal film into a film structure as the surface area of the metal film is minimized.

An interlocking device for a HIP equipment that prevents possible damage to the HIP equipment arising from use of a furnace or processing gas in error and can control the oxygen concentration and pressure within the HIP equipment. The device includes a sensor for detecting a concentration of oxygen in the processing gas in a processing gas pipe system. If the sensor detects an excessively high oxygen concentration, a supply side interlocking mechanism closes a valve for the pipe system and disconnects a power source for a furnace in a high pressure vessel. A flow switch is connected to a safety pipe system having a safety device, and a thermocouple is provided for each of the safety and processing gas pipe systems and a relief pipe system. When the flow switch detects processing gas being spouted from the safety pipe system and/or when one of the temperature signals from the thermocouples exceeds a preset value, a relief side interlocking mechanism closes the processing gas pipe system, opens the relief pipe system, stops a gas compressor and disconnects the power source.

This invention provides a filming method for covering the surface of the insulating film of a semiconductor substrate with a copper interconnect film free from pores. The surface of the insulating film 2 of a semiconductor substrate 1 is filmed with a copper or copper alloy 3 by any one of plating, CVD and PVD, and the whole body is then heated under a high-pressure gas atmosphere to cover the surface with an interconnect film 4 free from pores.
摘要:
A wiring film, which can be formed into wiring for ULSI semiconductor circuits, is formed by first forming holes in an insulating film on a substrate; then depositing a metallic material of copper, copper alloy, silver or silver alloy into the holes under an atmosphere including hydrogen; and finally annealing the deposited metallic material. The metallic material can be deposited by a sputtering process in which the atmosphere includes an inert gas in addition to the hydrogen. Hydrogen doped in the metallic material during the sputtering process promotes diffusion of atoms in the metallic material. The diffusion eliminates voids in the deposited metallic material.

The present invention provides a method for processing a substrate in which crystal defects occurring according to ion implantation can be prevented from being integrated to form defects such as dislocation or large vacancies in the manufacture of a SIMOX substrate by implanting oxygen atom to a Si base by ion implantation and reacting it with Si to form a buried oxide film. The annealing after ion implantation is performed under a gas atmosphere pressurized to, for example, about 100 MPa. In the pressurized state, a structure having a smaller volume is thermodynamically more stable, and a behavior as increases crystal distortion is arrested in the annealing. Thus, crystal defects can be laid in uniformly dispersed state, vacancies can be also extinguished, and a Si base of good quality suitable for manufacture of ULSI in which defects such as dislocation are reduced can be provided.
