WebThe MOSFET is designed so that the depletion layer can expand easily, so the N-layer (drift layer) is thick, and the impurity concentration is low. ⇒Resistance value is high when wanting to pass current through. The depletion layer only needs to extend a slight amount, so the N-layer (drift layer) is thin and the impurity concentration is high. http://www.hexinsemi.com/info/pingmiangoucaochaojiesgtigbtxiliemosfetjieshao.html

WebFig. 6 - Power MOSFET Cross Section Under Avalanche Typical modern power MOSFETs have millions of identical trenches, cells or many strips in parallel to form one device, as shown in figure 7. For robust designs, then, avalanche current must be shared among many cells/strips evenly. Failure will then occur randomly in a single cell, at a high ... Web(TMBS®) Trench MOS Barrier Schottky Rectifier Ultra Low VF = 0.53 V at IF = 5 A LINKS TO ADDITIONAL RESOURCES FEATURES • Trench MOS Schottky technology • Low forward voltage drop, low power losses • High efficiency operation • Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C • AEC-Q101 qualified available WebLOCOS也经过了数代的不断发展如Poly-buffered LOCOS, dual poly等等,先进工艺一般采用STI(shallow trench isolation)。 下图右上是一个掺杂区域内的STI,两个NMOS之间有厚且形状规整的氧化层隔开,并连接导线;该区域形成了一个寄生MOS,为了减小寄生电流,氧化层的深度和掺杂浓度都有严格要求,目的是增加 ... top pride auto group
