Abstract
A super junction power device with an adjustable gate resistance structure and a manufacturing method thereof relate to a field of manufacturing of power devices and semiconductors. The manufacturing method includes preparing a cell structure and an adjustable gate resistance structure of the super junction power device; preparing contact through holes; preparing a metal wire layer; and preparing a passivation layer. By designing an adjustable gate resistance structure, a gate resistance of the super junction power device is flexibly adjusted within a certain gate resistance range based on application requirements, further improving an application range of the super junction power device. Through adjustable gate resistance control electrodes, open-circuit control is performed on corresponding independent gate resistors to realize an adjustment of the corresponding gate resistor, There is no need to change a layout of a gate, contact holes, and metal wire layers for different gate resistance requirements.
