Abstract
A package with an integral window for housing a microelectronic device. The integral window is bonded directly to the package without having a separate layer of adhesive material disposed in-between the window and the package. The device can be a semiconductor chip, CCD chip, CMOS chip, VCSEL chip, laser diode, MEMS device, or IMEMS device. The package can be formed of a multilayered LTCC or HTCC cofired ceramic material, with the integral window being simultaneously joined to the package during cofiring. The microelectronic device can be flip-chip interconnected so that the light-sensitive side is optically accessible through the window. A glob-top encapsulant or protective cover can be used to protect the microelectronic device and electrical interconnections. The result is a compact, low profile package having an integral window that is hermetically sealed to the package prior to mounting and interconnecting the microelectronic device.
