Abstract :
This work demonstrates the availability of using porous silicon as semi-insulating substrate for β-SiC high temperature optical sensing devices. An MSM structure was fabricated both on a porous silicon substrate and a conventional silicon substrate, respectively. Experimental results show the optical current ratio can be improved up to 400% at room temperature and 3000% at 200°C operating temperature, respectively, with the porous silicon substrate
