Abstract
A fingerprint sensing device includes a substrate; a plurality of pixels arranged in a grid of rows and columns, each pixel having an active thermal sensing element therein; a first metal layer forming first addressing lines for addressing the active thermal sensing elements; a second metal layer above the first metal layer and forming second addressing lines for addressing the active thermal sensing elements; an electrically conductive ESD protection layer; and an insulating layer disposed between the ESD protection layer and the active thermal sensing elements. The ESD protection layer is electrically connected to a bias potential. The ESD protection layer is disposed in a pattern such that it partially overlaps each pixel, the ESD protection layer at least partially overlapping the active thermal sensing element of each pixel.
