摘要:
A method for fabricating a semiconductor card includes a printed circuit substrate upon which is mounted a card circuit including one or more semiconductor components such as dice or packages. External contacts link the card circuit to the circuit of another apparatus by removable insertion therein. The substrate is defined by a peripheral opening in a surrounding frame, which may be part of a multiframe strip. The substrate is connected to the frame by connecting segments. The card includes a first plastic casting molded to the substrate and encapsulating the semiconductor components while leaving a peripheral portion of the substrate uncovered. A second plastic casting is molded to the peripheral portion to abut the first plastic casting and form the card periphery.

Microelectronic imagers comprising imaging units and optics units with optics supports having threadless interfaces and methods for packaging such microelectronic imagers are disclosed herein. In one embodiment, the imaging unit can include a microelectronic substrate and a microelectronic die on and/or in the substrate. A first referencing element having one or more inclined steps arranged about an axis is fixed to the imaging unit. The imager can further include an optics unit having an optic member. A second referencing element having one or more complementary inclined steps is fixed to the optics unit. The second referencing element is seated with the first referencing element and at least one of the referencing elements can be rotatably adjusted with respect to the other to position the optic member at a desired location relative to the image sensor.

Various embodiments for moisture-resistant image sensor packaging structures and methods of assembly are disclosed. Image sensor packages of the present invention include an interposer, a housing structure formed on the interposer for surrounding an image sensor chip, and a transparent cover. The housing structure may cover substantially all of the interposer chip surface. In another embodiment, the housing structure also covers substantially all of the interposer edge surfaces. The housing structure may also cover substantially all of the interposer attachment surface. An image sensor chip is electrically connected to the interposer with sealed wire bond connections or with sealed flip-chip connections. The housing structure may include runners that enable simultaneous sealing of the interior of the image sensor package and of the transparent cover.
