Abstract
A readily manufacturable field controlled thyristor with a first semiconductor region of n-type conductivity, a second semiconductor region of p-type in contact with said first region, a void penetrating through said first and second semiconductor regions, a fourth semiconductor region of n-type forming a channel adjacent to said void, a fifth semiconductor region, of p-type, in contact with said third region. The device has a large tolerance for deviations in process parameter precision and accuracy, which enables the device to be produced at a low cost.
