Abstract:
A method for manufacturing a semiconductor device having a thyristor device with NDR characteristics, the method comprising:forming at least two contiguous regions of the thyristor device, said at least two contiguous regions being of opposite polarity; forming a control port that is located adjacent to, capacitively coupled to, and facing at least one of the regions of the thyristor device, the thyristor device including the control port and said at least two contiguous regions, the control port and said at least two contiguous regions being formed to provide at least preponderant control for switching of the thyristor device from a current-passing mode to a current-blocking mode in response to the control port coupling at least one edge of a first voltage pulse to said at least one of the regions, and from a current-blocking mode to a current-passing mode in response to the control port coupling at least one edge of a second voltage pulse to said at least one of the regions, each of the first and second voltage pulses having a common polarity.
