摘要
A threshold voltage model with an impurity concentration profile in a channel direction taken into account is provided in the pocket implant MOSFET. With penetration length of the implanted pocket in the channel direction and the maximum impurity concentration of the implant pocket used as physical parameters, the threshold voltage model is obtained by linearly approximating the profile in the channel direction. By analytically solving the model by using a new threshold condition with inhomogeneous profile taken into account, the threshold voltage can be accurately obtained. Based on thus obtained model, the threshold voltage can be predicted and can be used for circuit design.
