Abstract
A source mounted semiconductor device package is described which includes a semiconductor die having first and second opposing major surfaces, first and second major electrodes disposed on respective major surfaces and a control electrode disposed on the second major surface, and a thin metal clip electrically connected to the first major electrode of the die. The thin metal clip has a relatively large surface area, and package resistance which is caused by skin effect phenomenon is reduced thereby in high frequency applications.
Claims7
