Minority generation mechanisms of deep depleted MOS capacitor are discussed in this paper. The method to evaluate spatial distribution of the effective minority generation lifetime is proposed. The sample of low dose (implanted B) is measured. It is shown that the effective generation lifetime is gradually increased from the interface to the interior and the lifetime is a constant in a region deeper than 0.8μm
where the implanted boron does not penetrate.
