| 摘要 |
The present invention provides a method that forms individual semiconductor devices from a semiconductor substrate including a first face having a first region in which micro-mechanical elements are formed and a second region which surrounds the first region and in which a scribe line is formed, and a second face having a third region which is opposed to the first face and corresponds to the first region in which the micro-mechanical elements are formed and a fourth region which surrounds the third region and corresponds to the second region. The method includes steps of thinning the fourth region of the second face which corresponds to the scribe line formed in the second region of the first face, and cutting the semiconductor substrate along the scribe line formed in the second region of the first face.
