Design and modeling of PIN photodiode using MEMS technology

Abstract

This Paper describes a micro PIN photodiode model using Micro-electromechanical Systems (MEMS) technology. The model is developed using Comsol Multiphysics Software. This interface combines the semiconductor interface with the electromagnetic waves, frequency domain interface and is suitable for modeling direct band-gap optoelectronic semiconductor devices. This device is operated at a wavelength of 725 nm for the peak value of the current. The width and the height of the device is 0.5[μm] and 1[μm] respectively. This PIN photodiode can be uses as a light sensor for the solar applications like sun sensor, solar light, solar battery and solar instruments. It is also suitable for the industrial and inter terrestrial applications.
