The influence of soft breakdown on PMOSFETs is discussed based on the model of enhanced GIDL for NMOSFETs. The degradation due to thermal breakdown of the gate oxide was investigated in detail. As a conclusion, a careful selection of device parameters is necessary in order to detect a device...
MOSFET是金属氧化物半导体场效应晶体管(MetallicOxide SemiconductorField Effect Transistor)的简称,有时候我们也会简写成MOS。下面是一个典型的MOSFET结构。 所有MOSFET都有4个端口,栅极(Gate)、漏极(Drain)、源极(Source)以及衬底(Substrate)。一般来说衬底与源极可以连在一起,或接近于一个电势,所以画图时,我们有时...
数位科技的进步,如微处理器运算效能不断提升,带给深入研发新一代MOSFET更多的动力,这也使得MOSFET本身的操作速度越来越快,几乎成为各种半导体主动元件中最快的一种。MOSFET在数位信号处理上最主要的成功来自CMOS逻辑电路的发明,这种结构最大的好处是理论上不会有静态的功率损耗,只有在逻辑门(logic gate)的切换动作时才...
MOSFET栅极使用多晶硅取代了金属的原因MOSFET的栅极材料理论上MOSFET的栅极应该尽可能选择电性良好的导体,多晶硅在经过重掺杂之后的导电性可以用在MOSFET的栅极上,但是并非完美的选择。MOSFET使用多晶硅作为的理由如下:16
Furthermore, it was found first that high-frequency ac stress will cause the gate oxide breakdown at 200 °C. However, no gate oxide breakdown was found at 27 °C. By investigating the effects of...
