    摘要: A test structure for measuring a Micro-Electro-Mechanical System (MEMS) cavity height structure and calibration method. The method includes forming a sacrificial cavity material over a plurality of electrodes and forming an opening into the sacrificial cavity material. The method further includes forming a transparent or substantially transparent material in the opening to form a transparent or substantially transparent window. The method further includes tuning a thickness of the sacrificial cavity material based on measurements obtained through the transparent or substantially transparent window.
