    摘要: The shape of a tip of an insulating material of an insulating isolation region is provided as being a concave one recessed below the back surface of an n-semiconductor substrate. This reduces the electric field strength at the corner at which the bottom of the n-semiconductor substrate is in contact with the insulating isolation region to allow an excellent breakdown voltage to be obtained. Moreover, by forming a high impurity concentration region such as a field-stop layer on the back surface of the n-semiconductor substrate, a depletion layer extending from the top surface is prevented from reaching the back surface This eliminates an influence of a surface state introduced in the interface between the insulator film formed on the back surface and the n-semiconductor substrate, by which an excellent breakdown voltage can be obtained.

    摘要: An insulated gate thyristor is provided in which an inversion layer is created beneath a gate electrode to which a voltage is applied. An emitter region of a first conductivity type is biased to the same potential as a first main electrode via a MOSFET channel, and a thyristor portion consisting of the emitter region, a second base region of a second conductivity type, a base layer of the first conductivity type and an emitter layer of the second conductivity type is turned on. As electrons are injected uniformly from the entire emitter region, the insulated gate thyristor quickly shifts to the thyristor mode, and the on-voltage of the insulated gate thyristor of the invention is lowered. The insulated gate thyristor of the invention does not require a hole current that flows through the second base region of a convention EST in the Z-direction. In turning off, the pn junction recovers quickly without causing current localization, and the breakdown withstand capability if improved.
