Abstract:
1. A method for manufacturing a thyristor, the method comprising: forming a control port over a first base region in a semiconductor substrate; forming a spacing material laterally adjacent to a first side of the control port and over the first base region; implanting a dopant at an acute angle between the control port and the first base region to form a second base region using the control port and spacing material to mask a portion of the first base region, the formed second base region being laterally offset from the control port and at least a portion of the second base region being underneath the spacing material; and forming first and second emitter regions respectively coupled to the first and second base regions, the emitter and base regions forming a thyristor body, wherein the control port and the thyristor body are arranged such that the control port is adapted for capacitively coupling at least one edge of a voltage pulse at least to the first base region.
