Latest Patents
One of his latest patents is a method for manufacturing an SOI substrate. This invention aims to enhance the planarity of a surface of a single crystal semiconductor layer after separation. It achieves this by favorably separating a single crystal semiconductor substrate, even when using a non-mass-separation type ion irradiation method. The method involves irradiating a single crystal semiconductor substrate with accelerated ions while cooling it, bonding it with a base substrate, and then separating it along the embrittled region.
Another notable patent is the manufacturing method of a semiconductor device. This invention seeks to realize high performance and low power consumption by controlling the electric characteristics of a transistor according to its required function. It also aims to manufacture such a device with high yield and productivity without complicating the manufacturing process. This is achieved by adding an impurity element to a first semiconductor wafer to control the threshold voltage of a transistor before transferring the single crystal semiconductor layer to a second semiconductor wafer.
