Abstract

See full text

Provided are a wafer level package and a manufacturing method thereof. The wafer level package method includes preparing a patterned wafer, forming a recess in a position, in which a semiconductor chip is to be attached, of the patterned wafer through an etching process, fixing the semiconductor chip to the interior of the recess, and applying a passivation material to portions other than the semiconductor chip within the recess and to an upper end of the wafer. The wafer level package includes a silicon or glass wafer including a recess formed through etching and having an area larger than a semiconductor chip, a semiconductor chip fixed to the interior of the recess, and a passivation material filling an empty space other than the semiconductor chip within the recess and applied to a portion corresponding to an area larger than the semiconductor chip on an upper end of the wafer.
