摘要:
The invention concerns a method for producing miniature amplifier and signal processing unit. The method comprises the steps of: producing arrays of individual integrated circuits on a side of a wafer, where each circuit has a number of I/O connection points; providing a number of solder connection pads at each integrated circuit for redistribution of the I/O connection points of the integrated circuit; coating the side of the wafer having the solder connection pads with a protection coating and ensuing through going apertures in the coating to provide electrical contact with the solder connection pads; applying electrical components onto the coating and gaining electrical contact with the solder connection pads through the apertures of the coating material; singulating the individual amplifiers from the wafer and ensuring light protection of the edges and possible unprotected side of the amplifiers.

A raised on-chip planar inductor (12). An inductor (12) is fabricated on a substrate (14). The inductor (12), except for an anchoring extremity (24), is lifted from the substrate (14), preferably by application of a magnetic field to a magnetic layer (38) formed on the inductor (12). The lifting of the inductor (12) deforms a plastic bending region (26). After the magnetic field is removed, the inductor (12) remains raised with respect to the substrate (14).

A high frequency power amplifying device has two amplifying lines. Each amplifying line has a configuration in which a plurality of amplifying stages are connected in cascade having two source voltage terminals, of which one is connected to the first amplifying stage of one amplifying line and to the remaining amplifying stages of the other amplifying line, and the other, to the first amplifying stage of the latter amplifying line and to the remaining amplifying stages of the former amplifying line. An air core coil with a low D.C. resistance, formed by spirally winding a copper wire of about 0.1 mm in diameter, is connected in series between the final amplifying stage of each amplifying line and the source voltage terminal. Since there is no signal leak in each amplifying line from the final amplifying stage to the first amplifying stage and the D.C. resistance of the air core coil is low, oscillation margin can be improved. The air core coil is inexpensive, and accordingly can contribute to the cost reduction of the high frequency power amplifying device. Air core coils are fed by a bulk feeder and mounted over a module substrate.

An electronic assembly that includes a first electronic device. The first electronic device includes a cavity that extends into a back side of the first electronic device. The electronic assembly further includes a second electronic device. The second electronic device is mounted to the first electronic device within the cavity in the first electronic device. In some example forms of the electronic assembly, the first electronic device and the second electronic device are each a die. It should be noted that other forms of the electronic assembly are contemplated where only one of the first electronic device and the second electronic device is a die. In some forms of the electronic assembly, the second electronic device is soldered to the first electronic device.

A chip package is described (450). This chip package includes a stack of semiconductor dies (110-1,110-2,110-N) or chips that are offset from each other, thereby defining a terrace with exposed pads. A ramp component (112), which is positioned approximately parallel to the terrace, electrically couples to the exposed pads. Mechanical stops (460-1) are formed on respective semiconductor die for mechanical contact between the semiconductor die and the ramp component. The ramp component is electrically coupled to the semiconductor dies using microsprings (114). Consequently, the electrical contacts may have a conductive, a capacitive or, in general, a complex impedance. By removing the need for costly and area-consuming through-silicon vias ( TSV s) in the semiconductor dies, the chip package facilitates chips to be stacked in a manner that provides high bandwidth and low cost.

A system according to some examples herein includes a base chip which may include a plurality of attachment slots for attaching dies thereto. One or more of the attachment slots may be programmable attachment slots. The base chip may further include circuitry for interconnecting the dies attached to the base chip. For example, the base chip may include a plurality of cross bar switches, each of which is associated with respective ones of the plurality of attachment slots. The base chip may further include a configuration block, which is adapted to receive and transmit test signals for determining electrically connected signal lines of one or more attachment slots when one or more dies are attached to the base chip and which is further adapted to receive configuration data for programming signal (including power and ground) channels of the cross bar switches.
