Abstract: Simulating an electromagnetic response of a semiconductor structure for diffraction based optical metrology. The simulated electromagnetic response is used to determine an optical property of the semiconductor structure, such as a reflectivity coefficient. A rigorous coupled wave analysis (RCWA) is used to simulate reflectivity of the semiconductor structure layer by layer, and unit cell by unit cell. With a proper choice of a division point, the semiconductor structure can be separated into top and bottom portions that can be further sub-divided into smaller, identical unit cells in an X-Y plane. These unit cells can be simulated individually, and then the simulations can be combined to obtain the reflection coefficient of the entire semiconductor structure. This RCWA+unit cell simulation approach may decrease required simulation time, may not require calculation of a full scattering matrix, and/or has one or more other advantages compared to prior approaches.

The trained AI classifier can then be used to predict/estimate critical dimensions of critical dimensions of a fabricated or partially fabricated device.
