Abstract:
PURPOSE: A substrate test method and apparatus and a storage medium are provided to improve the test accuracy of an inspected substrate by controlling a distortion of an image due to the position and the location of an imaging device. CONSTITUTION: A substrate test method comprises the following steps. The coordinates of a reference point on a viewing coordinate system which is specified with a pixel group arranged in the matrix shape are acquired. The coordinates of the reference point are converted into coordinates on a viewing plane coordinate system. The coordinates of the reference point on the viewing plane coordinate system are converted into the coordinates of a camera coordinate system. The transform parameter of both coordinate systems is calculated and obtained. A substrate to be inspected is imaged with a camera. The image data on the viewing coordinate system is acquired. The obtained image data on the viewing coordinate system is converted into the image data on the viewing plane coordinate system. The image data on the viewing plane coordinate system is converted into the image data on the camera coordinate system. The image data on the camera coordinate system is converted into the image data on the world coordinate system. The inspection of the substrate is processed based on the image data on the world coordinate system.

Abstract:
The temperature of a heat plate is set to uniformly heat a wafer when heat treatment is actually performed. The temperatures of the wafer for temperature measurement are measured during a heat treatment period from a time just after the wafer is placed on the heat plate until a time when actual heat treatment time is passed. Whether temperature uniformity within a wafer plane is conforming or not is judged from the temperatures of the wafer during the heat treatment period, and when a negative judgment result is obtained, a correction value of a heat plate temperature setting parameter is calculated based on the measurement results by using a correction value calculating model, and the temperature setting parameter is changed.
