Latest Patents

One of his latest patents is focused on generic design rule checking (DRC) test case extraction. This innovation provides a computer-aided testing method for design verification of integrated circuits. The method involves generating a test case in design rule checking by extracting coordinates of an error marker for a first error identified in an integrated circuit design. It further includes identifying a rectangle that encloses the error marker and generating a test case based on the data contained within that rectangle. If the test case is not representative of the first error, the method identifies a second rectangle and generates a second test case based on the data within it.

Another significant patent involves a test method and structure for integrated circuits before complete metalization. This patent includes methods and test structures for an intermediate metal level of an integrated circuit. The method encompasses fabricating a first plurality of metal levels, performing functional tests on circuits positioned within these levels, and fabricating a second plurality of metal levels after the initial tests.
