This project aims to develop a prototype electric field induced second harmonic generation metrology setup for studying thin film dielectric interfaces on silicon in partnership with Femtometrix. The quality of these silicon-dielectric interfaces, which are affected by trapped charges and defects, are critical for microelectronic and optoelectronic device manufacturing. Through several proposed methodologies to separate the effect of interface and bulk signals, it is expected that the sensitivity of the prototype setup will exceed the previous record of 1 kV/cm. This metrology technique will be further expanded for applicability to silicon photovoltaics, specifically passivating contacts which cannot be studied via conventional techniques.

该项目旨在与 Femtometrix 合作开发一种原型电场感应二次谐波产生计量装置，用于研究硅上的薄膜电介质界面。这些硅-电介质界面的质量受到捕获电荷和缺陷的影响，对于微电子和光电器件的制造至关重要。通过几种提出的方​​法来分离界面和体信号的影响，预计原型设置的灵敏度将超过之前的 1 kV/cm 记录。这种计量技术将进一步扩展到硅光伏发电的适用性，特别是无法通过传统技术研究的钝化接触。
