Patent number: 10763108Abstract: Provided are methods for the selective deposition of material on a sidewall surface of a patterned feature. In some embodiments, the methods involve providing a substrate having a feature recessed from a surface of the substrate. The feature has a bottom and a sidewall which extends from the bottom. A conformal film is deposited on the feature using an atomic layer deposition (ALD) process. The conformal film deposited on the bottom is modified by exposing the substrate to directional plasma such that the conformal film on the bottom is less dense than the conformal film on the sidewall. The modified conformal film deposited on the bottom of the feature is preferentially etched. Also provided are methods for the selective deposition on a horizontal surface of a patterned feature.Type: GrantFiled: August 18, 2017Date of Patent: September 1, 2020Assignee: Lam Research CorporationInventors: Dennis M.

Patent number: 10748068Abstract: An approach for predictively scoring test case results in real-time. Test case results associated with a test run are received by a software testing environment. Using predictive statistical models, test case results and attribute relationships are matched against model rules and test case history. A statistical correlation and confidence parameter provide the ability to generate test case relationships for predicting the outcome of other test cases in the test run. The test case relationships are transformed into scoring results and output for the further processing.Type: GrantFiled: December 14, 2016Date of Patent: August 18, 2020Assignee: International Business Machines CorporationInventors: Kevin B.
