半导体装置的制造方法
摘要：
本发明提供一种半导体装置的制造方法，包括以下工序：对半导体基板的一个表面照射离子，从而在离所述一个表面有一定深度的区域中形成脆化层；在所述一个表面上或支撑基板上形成绝缘层；将所述一个表面和所述支撑基板与所述绝缘层接合；加热所述半导体基板，以使所述脆化层中产生裂缝；在所述脆化层中分离所述半导体基板，从而在所述支撑基板上形成半导体层；对所述半导体层照射电磁波；在照射所述半导体层之后对所述半导体层表面进行研磨处理；使用所述半导体层形成半导体元件；在所述半导体元件上形成发光元件；以及在所述发光元件上形成彩色滤光片。
摘要（英）：

It is an object of the present invention is to provide a method of manufacturing an SOI substrate provided with a single-crystal semiconductor layer which can be practically used even when a substrate having a low heat-resistant temperature, such as a glass substrate or the like, is used, and further, to manufacture a semiconductor device with high reliability by using such an SOI substrate. A semiconductor layer which is separated from a semiconductor substrate and bonded to a supporting substrate having an insulating surface is irradiated with electromagnetic waves, and the surface of the semiconductor layer is subjected to polishing treatment. At least part of a region of the semiconductor layer is melted by irradiation with electromagnetic waves, and a crystal defect in the semiconductor layer can be reduced. Further, the surface of the semiconductor layer can be polished and planarized by polishing treatment.
