This article presents a simple yet powerful general pinning process model for 3-D pinned photodiodes (PPDs), which can be used to model PPDs with small dimensions (miniature PPDs). For the development of a pinning model, capable of dealing with different PPD shapes and dimensions, the charge population in the space charge region (SCR) is calculated. Moreover, to improve the model’s accuracy, the PPD inner region depletion mechanism is investigated, and the inner SCR width is extracted analytically. The model’s application in analyzing PPDs is verified with six previously published experimental results.

一种能够进行微型 PPD 建模的通用紧凑型钉扎光电二极管模型


本文介绍了一个简单但功能强大的 3D 钉扎光电二极管 (PPD) 通用钉扎工艺模型，可用于对小尺寸 PPD（微型 PPD）进行建模。为了开发能够处理不同 PPD 形状和尺寸的钉扎模型，需要计算空间电荷区 (SCR) 中的电荷数量。此外，为了提高模型的精度，研究了PPD内部区域耗尽机制，并解析提取了内部SCR宽度。该模型在分析 PPD 方面的应用已通过之前发表的六项实验结果得到验证。
