REVERSE RECOVERY CHARGE REDUCTION IN SEMICONDUCTOR DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240014261 titled 'REVERSE RECOVERY CHARGE REDUCTION IN SEMICONDUCTOR DEVICES
Simplified Explanation
The abstract of the patent application describes a method for forming a diode junction in a semiconductor region by creating a well region of one conductivity type within the semiconductor region of another conductivity type.
