Abstract
A semiconductor component is formed in a semiconductor wafer, of a first conductivity type. The semiconductor component includes a plurality of first regions, of a second conductivity type, in a top surface of the wafer and coated with a first metallization layer. The semiconductor component further includes a second region, of the second conductivity type, and a third region, of the first conductivity type, each formed in the top surface of the wafer. A second metallization layer coats the second and third regions. A fourth region, of the first conductivity type, is formed in a bottom surface of the semiconductor wafer and opposes the first and second regions. A fifth region, of the second conductivity type, is also formed in the bottom surface and opposes the third region. A rear surface metallization covers the bottom surface of the semiconductor wafer.
