Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we studied a specified method of regions including dislocations which are crystallographic defects in a photoluminescence (PL) image of multicrystalline silicon wafers. We utilized a neural network of multilayer perceptron (MLP) to classify fragmented region in the wafer image to a region including dislocation or not. We examined effects in network's output depending on changes in the numbers of elements of the first hidden layer. In the comparison of conditions using 1 wafer image or 3 wafer images,
we obtained results that the network composed 3 hidden layers and the first hidden layer has about 10 elements with 3 wafers images shows good performance.
