Light sensing element and optical biometric sensor using same

The invention provides a light sensing element and an optical biometric sensor using the same. The light sensing element converts light energy into electric energy and at least comprises one or more main light receiving areas; the connecting region is directly connected to the one or more main light receiving regions to form a light receiving region with a reduced area; the light receiving regionhas one or more area reduction portions to reduce junction capacitance and increase sensing voltage signals. 本发明提供了一种光感测元及使用其的光学生物特征感测器，其中光感测元，将光能转换成电能，并且至少包括：一个或多个主收光区；以及一连接区，直接连接至该一个或多个主收光区，以形成一个削减面积的收光区，该收光区具有一个或多个面积削减部分，以降低接面电容并增加感测电压信号。
