Latest Patents

Williamson holds a patent for "Identifying yield-relevant process parameters in integrated circuit device fabrication processes." This patent describes a method where wafers are processed to build test structures. The wafers undergo processing in tools of process steps belonging to a process module. The test structures are tested to obtain defectivity data, and tool process parameters are monitored and collected as process tool data. Additionally, other information about the wafers, such as metrology data and product layout attributes, is also collected. A model is created to describe the relationship between defectivity data and process tool data, which is then used to relate the process tool data to the yield of the process module. The model can be an initial model using data from a limited number of test wafers or an expanded model using data from product wafers containing embedded test structures.
