摘要:
A method of making a plurality of sealed assemblies is provided which includes a) assembling a first element to a second element so that a bottom surface of the first element faces downwardly toward a front surface of the second element and a top surface of the first element faces upwardly away from the second element; and (b) forming ring seals surrounding regions of the front surface of the second element by introducing flowable material between the first element and the second element from the top surface of the first element through openings in the first element. A chip is provided which includes: (a) a body defining a front surface and one or more circuit elements on or within the body; (b) one or more bond pads exposed at the front surface in a bond pad region; and (c) a metallic ring exposed at the front surface, the ring substantially surrounding the bond pad region. Sealed chip assemblies are formed by sealing an array of the chips, e.g., in wafer form, to a cap element.

A packaged microelectronic device is provided which includes: (a) a unit having a chip with an upwardly-facing front surface and a downwardly-facing rear surface, a lid overlying at least a portion of the front surface of the chip, the lid having a top surface facing upwardly away from the chip and unit connections exposed at the top surface of the lid. At least some of the unit connections are electrically connected to the chip. The packaged microelectronic device also includes a package structure including structure defining package terminals, at least some of the package terminals being electrically connected to the chip. The package structure, the unit or both define a downwardly-facing bottom surface of the package, the terminals being exposed at the bottom surface.

A microelectronic package is provided in which a first chip having active elements, e.g. amplifying elements, and passive elements, e.g. resistors, capacitors and inductors, is mounted in electrical communication with a microelectronic element having conductive patterns opposing a front face of the first chip. Absorptive material patterns are disposed between the conductive patterns of the microelectronic element and at least some of the passive elements while leaving at least some of the active elements exposed so as to attenuate radio frequency energy propagated by wave between the passive devices and conductive patterns of the microelectronic element. A packaged chip is also provided in which a chip is disposed beneath a package element, the chip having an opening which extends between a front face and a rear face of the chip, a conductor being disposed in the opening which is conductively connected to a conductive element of the package element.

Provided are connection structures for a microelectronic device and methods for forming the structure. A substrate is included having opposing surfaces and a plurality of holes extending through the surfaces. Also included is a plurality of electrically conductive posts. Each post extends from a base to a tip located within a corresponding hole of the substrate. An additional substrate may be provided such that the base of each post is located on a surface thereof. Additional electrically conductive posts may be provided having tips in corresponding holes of the additional substrate. Optionally, a dielectric material may be placed between the substrate and the posts.

An electronic camera module incorporates a sensor unit (20) having a semiconductor chip (22) such as a CCD imager and a cover (34) overlying the front surface of the chip. An optical unit (50) includes one or more optical elements such as lenses (58). The optical unit has engagement features (64) which abut alignment features on the sensor unit as, for example, portions (44) of the cover outer surface (38), so as to maintain a precise relationship between the optical unit and sensor unit.

An array of chips spaced apart from one another by chip spacing distances, as, for example, an array of chips on a wafer dicing tape is juxtaposed with an array of chip receiving elements spaced apart from one another by receiving element spacing distances different from the chip spacing distances, as, for example, an array of substrates or fixtures spaced apart from one another at distances substantially larger than the chip spacing distances. The juxtaposing step is performed so that a set of chips including less than all of the chips in the array of chips is aligned with a set of the chip receiving elements. This set of chips is transferred to the set of chip receiving elements while the arrays are aligned with one another. The cycle may be repeated using the same or different array of chips, and using the same or different array of chip receiving elements. Numerous small chips can be transferred to large chip receiving elements without handling individual chips, and without the use of equipment such as pick-and-place equipment commonly used for such handling.
摘要:
According to one aspect of the invention, a capped chip is provided which includes a chip having a front surface, a back surface opposite the front surface and a plurality of bond pads exposed at at least one of the front and back surfaces. A cap is joined to the chip, the cap overlying one of the front and back surfaces of the chip. The cap includes a plurality of contacts which are conductively interconnected to the bond pads, and one or more temporary ties which conductively connect two or more of the contacts. The temporary ties are severable after the contacts are conductively interconnected to the bond pads.

Capped chips and methods of forming a capped chip are provided in which electrical interconnects are made by conductive elements which extend from bond pads of a chip at least partially through a plurality of through holes of a cap. The electrical interconnects may be solid, so as to form seals extending across the through holes. In some cases, stud bumps extend from the bond pads, forming parts of the electrical interconnects. In some cases, a fusible conductive medium forms a part of the electrical interconnects.

A covered chip having an optical element integrated in the cover is provided which includes a chip having a front surface, an optically active circuit area, and bond pads disposed at the front surface. The chip is covered by an at least partially optically translucent or transparent unitary cover that is mounted to the front surface of the chip, and has at least one optical element integrated in the unitary cover. The cover is further aligned with the optically active circuit area and vertically spaced from the optically active circuit area.

Lidded chip packages are provided in which an optoelectronic device chip has microelectronic circuits exposed at a surface of the chip with a lid mounted to overlie the optoelectronic device and the microelectronic circuits. An opaque film may be attached to the lid to overlie the microelectronic circuits while exposing the optoelectronic device. Lidded chip packages are also provided in which the lid overlies an active or passive device mounted to the chip. Wiring traces may be embedded within an adhesive between the lid and the chip.
