Latest Patents

Yasunishi's latest patents include a method for producing semiconductor devices that involves the formation of an ion implanted region by implanting magnesium ions into a predetermined area of the surface of the first p-type layer. Following this, a second n-type layer is created on the first p-type layer and the ion implanted region. A trench is then formed through dry etching, which allows for precise control over the diffusion of magnesium during heat treatment. This process ensures that the width of the p-type impurity region closely matches the width of the first p-type layer divided by the trench.

Another notable patent describes a method of manufacturing semiconductor devices that reduces the likelihood of corner formation in n-type semiconductor layers. This method involves creating a gallium nitride (GaN) based n-type semiconductor layer, followed by the formation of a groove and the application of a p-type semiconductor layer. The innovative approach allows for effective exposure of the n-type semiconductor layer, facilitating the formation of a metal electrode that contacts both layers.
