[0038] As described in the background art, realizing real-time detection of molecular-level defects in the manufacturing process is one of the problems to be solved in the field of semiconductor yield detection.
[0039] In order to solve the problem of real-time detection of molecular-level defects in the development and production of advanced semiconductor manufacturing processes due to new materials and process flows, embodiments of the present invention provide a semiconductor detection device and detection method. In the semiconductor detection device, the nonlinear optical signal used for detection can be sorted from the sum-frequency reflected light to characterize the photochemically active molecular distribution and molecules of the photoresist before exposure or the photoresist after exposure Structural information defects, so as to achieve non-destructive semiconductor device molecular-level defect detection.
[0040] In order to make the above-mentioned objects, feature...
