Abstract

A sensing device includes a first III-V compound stack and a second III-V compound stack. The first III-V compound stack has a first sensing area, and the second III-V compound stack has a second sensing area. A passivation layer fully covers the second sensing area. The first III-V compound stack is physically separated from the second III-V compound stack, and has material compositions and structures same as the second III-V compound stack.
