Techniques are disclosed for fabricating a relatively thin package for housing a micro component, such as an opto-electronic or MEMs device. The packages may be fabricated in a wafer-level batch process. The package may include hermetically sealed feed-through electrical connections coupling the micro component to electrical contacts on an exterior surface of the package.

Method of fabricating a package for a micro component

A passive alignment technique is disclosed to facilitate accurate positioning of components of an optical assembly. In one aspect, a method includes directing light onto components of an optical assembly in which a first component includes a first pattern of marks with a first frequency and a second component includes a second pattern of marks with a second different frequency. An optical signal corresponding to the superposition of the first and second patterns is detected. Based on the detected optical signal, a determination may be made as to whether the first and second components are properly positioned with respect to one another.

Accurate positioning of components of an optical assembly

Techniques are disclosed for hermetically sealing one or more devices within a package. According to one aspect, a lid is attached to a substrate on which one or more devices are provided such that the devices are encapsulated within an area defined by the substrate and the lid. A substance, such as a lubricant or gas, is introduced via one or more through-holes in the lid to a region that is separated from the devices by a wall having at least one opening through which the substance can pass to the devices. The through-hole then may be hermetically sealed, for example, using a local heating process that does not degrade the lubricant or other substance.
