Abstract: A Leadless Chip Carrier (LCC) device and method of attaching a Microelectromechanical (MEMS) device into an LCC package. An alignment plate is die bonded into the bottom of an LCC. The alignment plate includes fiducials fabricated into top and bottom metal layers, thus producing a tolerance that will be an order of magnitude better than the tolerance of fiducials included in the LCC. A bump pattern and MEMS die are attached based on the alignment plate and fiducials giving a much improved die to bump alignment.

Abstract: An automated process for performing MEMS packaging including automatically attaching a die to a chip carrier, resulting in a chip carrier assembly, automatically moving the chip carrier assembly into a vacuum chamber, wherein the vacuum chamber includes one or more lids therein, automatically securing a lid to the chip carrier assembly within the vacuum chamber, thereby forming a packaged die, and automatically removing the packaged die from the vacuum chamber. Unique vacuum chambers suitable for MEMS packaging are also disclosed.

Abstract: A method for assembling a micro-electromechanical system (MEMS) device that includes a micro-machine is described. The method comprises forming the micro-machine on a die, the die having a top surface and a bottom surface, providing a plurality of die bonding pedestals on a surface of a housing, and mounting at least one of the top surface of the die and components of the micro-machine to the die bonding pedestals such that a bottom surface of the die at least partially shields components of the micro-machine from loose gettering material.

Abstract: A method for reducing occurrences of loose gettering material particles within micro-electromechanical system (MEMS) devices is described. The MEMS devices include a micro-machine within a substantially sealed cavity formed by a housing and a cover for the housing. The cavity containing a getter mounted on a getter substrate which is to be attached to the cover. The method includes providing an area between a portion of the cover and a portion of the getter substrate, positioning the getter within the area, and attaching the getter substrate to the cover.
