To do this, we must develop a method of identifying dust particles. However, the current method of inspecting LSI wafers depends on human judgment; this makes it difficult to develop an algorithm to identify dust particles with complex shapes because mathematical models of dust particles have not been created. With this study, we propose the so\u2010called \u201cstochastic fractal variable\u201d to make the mathematical model and identify the dust particles by using the maximum\u2010likelihood method. Furthermore, we confirm the effectiveness of the identification method we propose by categorizing actual data.<\/jats:p>","DOI":"10.1002\/scj.4690260408","type":"journal-article","created":{"date-parts":[[2007,11,16]],"date-time":"2007-11-16T09:16:40Z","timestamp":1195204600000},"page":"74-83","source":"Crossref","is-referenced-by-count":0,"title":["Identification for complicated shape objects by using stochastic fractal variables\u2014categorizing dust particles on LSI wafer surface"],"prefix":"10.1002","volume":"26","author":[{"given":"Masayoshi","family":"Kamijo","sequence":"first","affiliation":[]},{"given":"Shin\u2010Ichi","family":"Aihara","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,22]]},"reference":[{"issue":"12","key":"e_1_2_1_2_2","first-page":"2605","article-title":"3\u2010D natural shape analysis by using fractal and its application to topographic model generation","volume":"70","author":"Yokoya N.","year":"1987","journal-title":"I.E.I.C.E.
