Summary :

A new cell structure Power MOSFET, which exhibits a lower on-state resistance and lower gate charge than the conventional layout geometry, is proposed in this research. Vertical Power MOSFETs are generally designed by either squared (closed) cell or stripe (linear) cell geometry; each has its own advantages and drawbacks. Typically, closed cell design has lower on resistance but higher gate charge characteristics than the linear one. In this study, we propose, fabricate, and analyze a "wing cell" structure Power MOSFET, which can have lower on resistance and lower gate charge performances than the closed cell structure. In addition, the wing cell design can avoid the "closed concept" patents.
