摘要:
The present invention relates to a method and apparatus for separating out metal copper according to an electroplating of copper using, for example, a solution of copper sulfate to produce copper interconnections on a surface of a substrate. The substrate is brought into contact, at least once, with a processing solution containing at least one of organic substance and sulfur compound which are contained in a plating solution. Thereafter, the substrate is brought into contact with the plating solution to plate the substrate.
摘要:
A substrate is plated with a metal film of uniform thickness only in a limited area thereof which is to be plated. A substrate plating apparatus has a substrate holder for holding a substrate and a plating cell for plating a portion of a surface, to be plated, of the substrate held by the substrate holder. The plating cell has an anode disposed so as to cover the portion of the surface, to be plated, of the substrate held by the substrate holder, a cathode for supplying a current to the surface, to be plated, of the substrate in such a state that the cathode is brought into contact with the substrate, a plating liquid supplying device for supplying a plating liquid between the anode and the surface, to be plated, of the substrate, and a power source for applying a voltage between the anode and the cathode.

摘要:
The gist is that the close-packed plane of a single crystal forming an electrode line such as electrodes or lines of a semiconductor device whose active regions are reduced in size, i.e., highly integrated, is arranged parallel to the longitudinal direction of the line; or in the case of a polycrystalline electrode line, the angle formed between the normal line direction of the close-packed plane of its crystal grains and that of the electrode line is arranged to be 80° or less.

A reliability evaluation test apparatus (10) of this invention includes a wafer storage section (12) which stores a wafer (W) in a state wherein the electrode pads of a number of devices formed on the wafer and the bumps of a contactor (11) are totally in electrical contact with each other. The wafer storage section (12) transmits/receives a test signal to/from a measurement section (15) and has a hermetic and heat insulating structure. The wafer storage section (12) has a pressure mechanism (13) which presses the contactor (11) and a heating mechanism (14) which directly heats the wafer (W) totally in contact with the contactor (11) to a predetermined high temperature. The reliability of an interconnection film and insulating film formed on the semiconductor wafer are evaluated under an accelerated condition.

A reliability tester (10) comprises a wafer containing section (12) containing a wafer (W) in the state that electrode pads of many devices formed on the wafer are all in electrical contact with bumps of a contactor (11). This wafer containing section (12) transmits/receives test signals with a measuring section (15) and has a hermetic and heat-insulating structure. The wafer containing section (12) has a pressing mechanism (13) for pressing the contactor (11) and a heating mechanism (14) for directly heating the wafer (W) in all contact with the contactor (11) to a predetermined high temperature. Thus, this tester evaluates the reliability of a wiring film and that of an insulation film formed on the semiconductor wafer under an acceleration condition.
