摘要:
An apparatus and method for packaging an electronic device that mechanically isolates the electronic device from its supporting substrate, eliminating transfer of mechanical stress from the substrate to the device. The apparatus includes a plurality of elongated members that extend from a frame support to a center opening, where the ends of the elongated members together support the electronic device. The shape, material and orientation of the elongated members combine to both support the electronic device and absorb mechanical force transmitted from the substrate to the support frame. In one example, the absorbing portion is substantially perpendicular to the direction of the transmitted force and the transmitted force is absorbed by mechanical displacement of one end of the perpendicular portion. The apparatus and method are particularly effective in eliminating the negative effects of thermal expansion mismatch between the electronic device and its supporting substrate.

Methods of affixing a device to a support structure are disclosed. In an embodiment, the device includes a face on which is disposed at least one electrical connector. The method includes forming a ribbon suspender having a width, a first connection portion, a second connection portion, and a support portion coupling the first connection portion to the second connection portion. The support portion defines an apex portion of the ribbon suspender. The apex portion is bonded to the device. The first and second connection portions of the ribbon suspender are bonded to the support structure. The support portion of the ribbon suspender flexes to accommodate acceleration of the support structure.

A Micro ElectroMechanical Systems device according to an embodiment of the present invention is formed by dicing a MEMS wafer and attaching individual MEMS dies to a substrate. The MEMS die includes a MEMS component attached to a glass layer, which is attached to a patterned metallic layer, which in turn is attached to a number of bumps. Specifically, the MEMS component on the glass layer is aligned to one or more bumps using windows that are selectively created or formed in the metallic layer. One or more reference features are located on or in the glass layer and are optically detectable. The reference features may be seen from the front surface of the glass layer and used to align the MEMS components and may be seen through the windows and used to align the bumps. As an end result, the MEMS component may be precisely aligned with the bumps via optical detection of the reference features in the glass layer.
