摘要:
In a two-pole SMT miniature housing in leadframe technique for semiconductor components, a semiconductor chip is mounted on one leadframe part and is contacted to a further leadframe part. The further leadframe part is conducted out of the housing in which the chip is encapsulated as a solder terminal. No trimming or shaping process is required and the housing is tight and is capable of further miniaturization. The solder terminals as punched parts of the leadframe are conducted projecting laterally from the housing sidewalls residing opposite one another at least up to the housing floor which forms the components' mounting surface. The chip mounting surface and the components' mounting surface form a right angle with one another.

An image sensor package (10) includes a housing (34) defining a top opening, an image sensor (14) received in the housing, and a converging lens (36) covering the opening to hermetically seal the housing and form a window for light to pass through into the housing. The image sensor has an active area which faces the converging lens and which is responsive to light. The converging lens not only provides hermetic sealing for the housing, but also converges light before the light strikes the active area of the image sensor. Accordingly, a focal length F is reduced, and a size of the image sensor package and the image sensor system can be reduced.

Microelectronic imagers, methods for packaging microelectronic imagers, and methods for forming electrically conductive through-wafer interconnects in microelectronic imagers are disclosed herein. In one embodiment, a microelectronic imaging die can include a microelectronic substrate, an integrated circuit, and an image sensor electrically coupled to the integrated circuit. A bond-pad is carried by the substrate and electrically coupled to the integrated circuit. An electrically conductive through-wafer interconnect extends through the substrate and is in contact with the bond-pad. The interconnect can include a passage extending completely through the substrate and the bond-pad, a dielectric liner deposited into the passage and in contact with the substrate, first and second conductive layers deposited onto at least a portion of the dielectric liner, and a conductive fill material deposited into the passage over at least a portion of the second conductive layer and electrically coupled to the bond-pad.

An electronic module adapted to sense light and configured to minimize the entry of stray light into the module. The module includes a housing having an opening through which light enters the housing, a first substrate coupled to the housing, a second substrate on the first substrate opposite the housing, and a chip on the second substrate. The first substrate defines a window aligned with the housing so that light traveling through the housing also passes through window. The second substrate defines an opening aligned with the window, and the chip is located over the opening in the second substrate so that a light-sensing element on the chip senses light passing through the opening. The module is equipped with features that prevent light from entering the module through the second substrate, the first substrate, and between the chip and second substrate.

A thin-film fingerprint sensor package primarily comprises a fingerprint sensor chip, a plurality of bumps, a wiring film, an encapsulant and a metal base to mechanically hold the fingerprint sensor chip. A sensing area is formed on the active surface of the fingerprint sensor chip. The bumps are disposed on the active surface. The wiring film has an opening to expose the sensing area and comprises a plurality of leads bonded to the bumps. The wiring film further has a ground lead electrically connecting the fingerprint sensor chip to the metal base. Therefore, the fingerprint sensor package can provide ESD protection during fingerprint recognition to avoid the damage of the fingerprint sensor chip.
