Title: Method for inspecting semiconductor device and method for manufacturing semiconductor device
Inventor: SAKURAI YASUO
IPC: H01L21/822
Filed: 2000-07-03
Abstract: PROBLEM TO BE SOLVED: To enhance productivity by detecting a defect generated in the preceding process by inline test and reducing time loss incident to investigation of the cause of defect. SOLUTION: Following to a step (S1) for forming a first interlayer film and making contact holes, a first metallization for inspection mask is formed (S8) and leak current test or function test is conducted by inline test using a probe (S7). Following to the inline test (S7), the first metallization of the inspection mask is removed (S9) and a first metallization layer forming step (S2) of a mask for actual circuit forming a semiconductor device is conducted. In other words, a metallization layer can be formed by an inspection mask on a silicon wafer and a semiconductor device can be inspected after formation.  Since abnormal yield can be found in the early stage and the factor of defect can be separated between a preceding step and a following step by conducting leak current test or function test of a semiconductor device, time loss incident to investigation of the cause of defect can be reduced and productivity can be enhanced.
