A single piece type capacitive touch panel uses an etching process to form a frame on periphery of a transparent substrate. The compactable pessary easily expands once inside a patient’s vagina, remaining firmly anchored in the vaginal cavity during movement, thereby effectively countering the effects of any prolapsing organ. A third passivation layer is further applied on the semiconductor substrate and has a plurality of openings for exposing a portion of the metallic layer, wherein each of the openings is shifted in position from a corresponding one of the bonding pads by a distance not exceeding a radius of the bonding pad.
