Patent number: 8052885Abstract: Structural modification using electron beam activated chemical etch (EBACE) is disclosed. A target or portion thereof may be exposed to a gas composition of a type that etches the target when the gas composition and/or target are exposed to an electron beam. By directing an electron beam toward the target in the vicinity of the gas composition, an interaction between the electron beam and the gas composition etches a portion of the target exposed to both the gas composition and the electron beam. Structural modifications of the target may be conducted by means of etching due to interaction between the electron beam and gas composition.Type: GrantFiled: January 12, 2007Date of Patent: November 8, 2011Assignee: KLA-Tencor CorporationInventors: Mehran Naser-Ghodsi, Garrett Pickard, Rudy F.

Patent number: 7945086Abstract: A first embodiment of the invention relates to a method for evaluating the quality of structures on an integrated circuit wafer. Test structures formed on either on the integrated or on a test wafer are exposed to an electron beam and an electron-beam activated chemical etch. The electron-beam activated etching gas or vapor etches the test structures, which are analyzed after etching to determine a measure of quality of the test structures. The measure of quality may be used in a statistical process control to adjust the parameters used to form device structures on the integrated circuit wafer. The test structures are formed on an integrated circuit wafer having two or more die. Each die has one or more integrated circuit structures. The test structures are formed on scribe lines between two or more adjacent die. Each test structure may correspond in dimensions and/or composition to one or more of the integrated circuit structures.Type: GrantFiled: January 12, 2007Date of Patent: May 17, 2011Assignee: KLA-Tencor Technologies CorporationInventors: Yehiel Gotkis, Sergey Lopatin, Mehran Nasser-Ghodsi
