Abstract:
1. A fabricating method of a sensor element array, comprising: forming a first patterned conductive layer on a substrate, the first patterned conductive layer comprising a sensing line, a first power line, a source/drain pattern, and a branch pattern, the sensing line, the first power line and the source/drain pattern being separated individually, and the branch pattern being connected to the first power line, wherein the source/drain pattern comprises a first section next to the sensing line and a second section next to the branch pattern; forming a channel layer on the first patterned conductive layer, the channel layer comprising a first channel connecting the first section with the sensing line and a second channel connecting the second section with the branch pattern; forming an insulating material layer and a conductive material layer sequentially over the substrate and patterning the insulating material layer and the conductive material layer to form a first insulation layer and a second patterned conductive layer, such that margins of the first insulation layer and the second patterned conductive layer are substantially overlapped, wherein the second patterned conductive layer includes a selecting line, a gate pattern, and a gate connecting pattern, the selecting line traverses the sensing line and the first section of the source/drain pattern and is disposed over the first channel, the gate pattern is disposed over the second channel, and the gate connecting pattern is connected to the gate pattern; forming a second insulation layer on the second patterned conductive layer, where the second insulation layer has a first connecting opening for exposing the gate connecting pattern; and forming a third patterned conductive layer on the second insulation layer, where the third patterned conductive layer comprises a sensing electrode electrically connected to the gate connecting pattern.
