摘要:
A method of fabricating a package with a light emitting device includes depositing a first metallization to form a conductive pad on which the light emitting device is to be mounted and to form one or more feed-through interconnections extending through a semiconductor material that supports the conductive pad. Subsequently, a second metallization is deposited to form a reflective surface for reflecting light, emitted by the light emitting device, through a lid of the package. Deposition of the second metallization is de-coupled from deposition of the first metallization.

A submount for a micro-component includes a semiconductor substrate having a cavity defined in a front-side of the substrate in which to mount the micro-component. The submount also includes a thin silicon membrane portion at a bottom of the cavity and thicker frame portions adjacent to sidewalls of the cavity. The substrate includes an electrically conductive feed-through connection extending from a back-side of the substrate at least partially through the thicker silicon frame portion. Electrical contact between the feed- through connection and a conductive layer on a surface of the cavity is made at least partially through a sidewall of the cavity.

A package includes a cap (22) with a solid-state light emitting device (30) mounted within a recess (28) in the cap. A plate (24) is attached to the cap to define a hermetically sealed region in which the light emitting device is housed, and a base (26) is attached to the plate. The plate and base are transparent to a wavelength of light emitted by the light emitting device. An optical wavelength selective element (52) is disposed between the plate and the base to select the wavelength of light to exit the package through the base.
摘要:
A package includes a sensor die with a micro component, such as a MEMS device, coupled to an integrated circuit which may include, for example., CMOS circuitry, and one or more electrically conductive bond pads near the periphery of the sensor die. A semiconductor cap structure is attached to the sensor die. The front side of the cap structure is attached to the sensor die by a seal ring to hermetically encapsulate an area of the sensor die where the micro component is located. The bond pads on the sensor die are located outside the area encapsulated by the seal ring. Electrical leads, which extend along outer side edges of the semiconductor cap structure from its front side to its back side, are coupled to the micro component via the bond pads.

A package for a MEMS device includes a semiconductor cap structure and a lid substrate that define an encapsulated area within which the MEMS device is located. Feed-through metallization hermetically seals micro-vias in the semiconductor cap structure and extends through the semiconductor cap structure to provide interconnections coupled electrically to the MEMS device and to an exterior of the semiconductor cap structure.

An optical module, such as a package for a vertical cavity surface emitting laser diode (VCSEL) or other light emitting device, includes monitoring of the emitted optical power by tapping the transmitted beam. The module includes a substrate, which carries the light emitting device and an optical monitor. In addition, the module includes a transparent plate with at least two reflective regions that together redirect part of the light from the light emitting device to the optical monitor.

Techniques and structures for three-dimensional inductive micro components are disclosed. The inductive micro components may be used, for example, in micro circuits and may be integrated with other components hermetically sealed in a micro housing. In some implementations, the inductive micro component may be tunable.
