Abstract

FIELD: semiconductor power devices. SUBSTANCE: reverse-conducting power thyristor has main- thyristor and diode regions that form two adjacent regions of device semiconductor structure and are isolated from each other at their adjacent boundaries by insulating region; it also has auxiliary-thyristor region placed between main thyristor region and central gate electrode; all regions are metallized, except for p-layer surface of insulating region; the latter, if projected on plane parallel to planes of p-n junctions, looks like two similar radially directed sections; auxiliary-thyristor region has gap facing diode region. EFFECT: improved loading capacity of thyristor and its noise immunity in control circuit due to enlarged active area of device. 2 cl, 6 dwg

Изобретение относится к конструкции интегрального силового полупроводникового прибора - тиристора, проводящего в обратном направлении, и может быть использовано при создании новых типов тиристоров. Цель: повышение нагрузочной способности тиристора и его помехоустойчивости по цепи управления за счет увеличения активной площади прибора. Для этого в силовом тиристоре, проводящем в обратном направлении и содержащем зоны основного тиристора и диода, которые образуют две смежные области полупроводниковой структуры прибора и разделены между собой по своим смежным границам изолирующей зоной, зону вспомогательного тиристора, которая расположена между зоной основного тиристора и центральным управляющим электродом, и снабженного металлизациями всех зон за исключением поверхности p-слоя изолирующей зоны, изолирующая зона в проекции на плоскость, параллельную плоскостям p-n-переходов, выполнена в виде двух одинаковых радиально направленных участков, а зона вспомогательного тиристора выполнена с зазором, который обращен в сторону диодной зоны.The invention relates to the design of an integrated power semiconductor device - a thyristor, conducting in the opposite direction, and can be used to create new types of thyristors. Purpose: to increase the load capacity of the thyristor and its noise immunity along the control circuit by increasing the active area of the device. To do this, in the power thyristor, conducting in the opposite direction and containing the zones of the main thyristor and the diode, which form two adjacent areas of the semiconductor structure of the device and separated by their adjacent boundaries by the insulating zone, the zone of the auxiliary thyristor, which is located between the zone of the main thyristor and the central control electrode, and equipped with metallization of all zones except the surface of the p-layer of the insulating zone, the insulating zone in projection onto a plane parallel to the planes of pn-ne ehodov is formed as a radially directed two identical portions, and an auxiliary thyristor zone is formed with a gap, which faces the diode zone.
