Abstract
The present disclosure relates to a manufacturing method for a packaging substrate and a packaging substrate utilizing the method. The packaging substrate according to the present disclosure includes; a core layer including a glass substrate having first and second surfaces facing each other and a cavity portion; an insulating layer formed on the first surface; and a light transmitting portion formed on an upper surface of the insulating layer, wherein a light receiving portion is disposed in the cavity portion, the insulating layer includes a via penetrating in a thickness direction, and a portion of a lower surface of the light transmitting portion may abut on the via. Though it, the packaging substrate may be compactly manufactured by reducing the space for the configuration of electrically connecting the conventional photoelectric elements, and the effect of improving the sensing efficiency and performance of the photoelectric sensor relative to the space may occur.
