STACKING TYPE WAFER LENS AND MANUFACTURING METHOD THEREOF AND CAMERA MODULE HAVING IT

摘要

A laminated-typed wafer lens, a manufacturing method thereof, and a camera module including the laminated-typed wafer lens are provided to decrease tolerance which is generated in spacer adhesion by forming an interval maintaining hole between the lenses. A plurality of the wafer lenses(WL1,WL2) comprise a lens formed on an upper part and a lower part of a lens substrate(S1,S2). A spacer(111,121) is formed on both sides of the surface which is formed to an opposite direction among the wafer lenses. An interval maintaining hole is positioned between the spacer and the wafer lens. The interval maintaining hole maintains intervals to prevent contact of the lenses facing each other.
