Granted: 2002-01-21
Abstract: The present invention provides a method of manufacturing a semiconductor integrated circuit, and particularly a method of manufacturing a high speed semiconductor integrated circuit. A silicon nitride film 60 is formed on a substrate 2 so as to cover semiconductor devices 10, 20. After having formed more than one layer of conducting members 66, 70 and interlayer dielectric films 62, 68a, 68b on the silicon nitride film, an opening 74 is formed in said interlayer dielectric films so as to reach the silicon nitride film 60. The substrate with thus defined opening 74 is etched in an etching solution containing hydrogen fluoride acid therein to remove away the silicon oxide interlayer films 62, 68a, 68b. As the silicon oxide interlayer films 62, 68a, 68b are etched in the solution, this forms electrical interconnection that is not surrounded with any oxides. As the silicon nitride film 60 works as an etching stop layer in this etching above, the semiconductor devices 10, 20 are protected against the etching process.
