SEMICONDUCTOR FILM THICKNESS PREDICTION USING MACHINE-LEARNING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18075216 titled 'SEMICONDUCTOR FILM THICKNESS PREDICTION USING MACHINE-LEARNING
The abstract describes a patent application for using a machine-learning model to estimate film thickness from spectral images captured during semiconductor substrate processing. Simulated images are generated for various predefined thickness profiles to train the model.
- Simulated training data is generated by simulating a light source reflecting off the film on a semiconductor substrate and capturing the spectral data with a camera.
- The captured spectral data is converted into images for wafers with different film thickness profiles, which are then labeled for training the machine-learning model.

Original Abstract Submitted
A machine-learning model may be used to estimate a film thickness from a spectral image captured from a semiconductor substrate during processing. Instead of using actual measurements from physical substrates to train the model, simulated images may be generated for a wide variety of predefined thickness profiles. Simulated training data may be rapidly generated by receiving a film thickness profile representing a film on a semiconductor substrate design. A light source may be simulated being reflected off of the film on the semiconductor substrate and being captured by a camera. The spectral data captured by the camera may be converted into one or more images for a wafer with the film thickness profile. The images may then be labeled with thicknesses from the film thickness profile for training a machine-learning model.
