Abstract
A semiconductor device includes a sensing element including a sensing electrode and a filter covering the sensing electrode. The filter includes a first work function layer and a second work function layer. The first work function layer is over the sensing electrode. The second work function layer is over the first work function layer. A work function value of the second work function layer is greater than a work function value of the first work function layer, and an atomic percentage of metal in the second work function layer is greater than an atomic percentage of metal in the first work function layer.
