发明名称 TEST STRUCTURE FOR MONITORING LINER OXIDATION
摘要 Embodiments of a method for forming a device using test structures are presented. The method includes providing a wafer with a device layer. The device layer includes a main device region and a perimeter region. The device layer is patterned with active and test patterns. Test patterns include dummy patterns disposed in a test device area. The wafer is processed to form at least one test device disposed in the perimeter region and one or more active devices disposed in the main device region. The test device determines a design window of the one or more active devices. Additional processing is performed to complete forming the device.
