VDMOSFET终端场板的设计考虑
Design Consideration of the Field Plate of Terminal VDMOSFET
【摘要】 对最基本的场板结构 ,通过理论推导 ,深入讨论了场板下氧化层厚度与击穿电压、氧化层玷污所带正电荷电量之间的关系 ;又给出了场板长度值与击穿电压和P+区结深之间的关系 .为VDMOSFET的结构设计和工艺实施提供了理论的依据
【Abstract】 Based on essenticial structure of VDMOSFET field plate and theoretical deduction, detail discussion of two connections that are the connections among oxidic thickness under the field plate, breakdown voltage and surface charge in the oxide and the connections among the length of field plate, breakdown voltage and junction depth of P + are presented. Theoretical foundation is provided for VDMOSFET structure design and technological practice.
