ABSTRACT:
A low-inductance semiconductor apparatus has a flat-topped base which support a semiconductor element. A cathode whose height is roughly on the order of its diameter sits atop the semiconductor element. The cathode has a flat upper surface with a threaded hole formed in the center thereof into which a lead with a threaded end can be screwed. The inside of the semiconductor apparatus is sealed by a cap which is secured in an airtight manner to the cathode and to a casing which is secured to the top surface of the base. The base can be either flat-bottomed or studded.
