Patent number: 5711848Abstract: A method for testing a semiconductor wafer processing step. An overlying electrical structure is created on a bare wafer to form a test wafer which simulates the surface contours of production wafers that will be exposed to the tested processing step. The overlying electrical structure of the test wafer is created using the same processing steps are used in manufacturing the overlying electrical structures of production wafers. Although the test wafers have the same surface contour as the production wafers they simulate, the test wafers are less expensive to manufacture because the test wafers do not include any underlying layers found in the production wafers which are not exposed during the tested processing step, and therefore the steps which form these layers can be omitted when making test wafers.Type: GrantFiled: June 6, 1995Date of Patent: January 27, 1998Assignees: Sony Corporation, Sony Electronics, Inc.Inventor: Armando Iturralde

Patent number: 5665640Abstract: A method and apparatus for depositing a film on a substrate by plasma-enhanced chemical vapor deposition at temperatures substantially lower than conventional thermal CVD temperatures comprises placing a substrate within a reaction chamber and exciting a first gas upstream of the substrate to generate activated radicals of the first gas. The substrate is rotated within the deposition chamber to create a pumping action which draws the gas mixture of first gas radicals to the substrate surface. A second gas is supplied proximate the substrate to mix with the activated radicals of the first gas and the mixture produces a surface reaction at the substrate to deposit a film. The pumping action draws the gas mixture down to the substrate surface in a laminar flow to reduce recirculation and radical recombination such that a sufficient amount of radicals are available at the substrate surface to take part in the surface reaction.Type: GrantFiled: June 3, 1994Date of Patent: September 9, 1997Assignees: Sony Corporation, Materials Research Corp.Inventors: Robert F.
