摘要
Wafer level encapsulated packages includes a wafer, a glass substrate hermetically sealed to the wafer, and an electronic component. The glass substrate includes a glass cladding layer fused to a glass core layer and a cavity formed in the glass substrate. The electronic component is encapsulated within the cavity. In various embodiments, the floor of the cavity is planar and substantially parallel to a plane defined by a top surface of the glass cladding layer. The glass cladding layer has a higher etch rate in an etchant than the glass core layer. In various embodiments, the wafer level encapsulated package is substantially optically transparent. Methods for forming the wafer level encapsulated package and electronic devices formed from the wafer level encapsulated package are also described.
