    Abstract

    Halo implants are used in modern CMOS technology to reduce the short channel effect. However, the lateral non-uniformity of the channel doping has been proven to degenerate the mismatch performance. With this paper we want to discuss the influence of the halo profile on MOS transistor mismatch. The analysis is conducted through random dopant fluctuations simulations on both short and long transistors. Parameters such as doping level and lateral diffusion are varied having a huge effect on the transistor mismatch performance. Therefore we show that, by engineering the halos, the matching can be improved significantly even when the devices nominally have the same electrical performances
