摘要:
A sensor chip package assembly and an electronic device having the sensor chip package assembly are disclosed, where the sensor chip package assembly includes: a metal substrate (100) which has a bonding pad region (11) and a placement region (12), the bonding pad region having a plurality of metal bonding pads (13); a sensor chip (200) which is located on an upper surface of the metal substrate, and the sensor chip having a plurality of sensor chip bonding pads (21); an electrical connection assembly (300) which electrically connects a metal bonding pad and a sensor chip bonding pad; and a packaging material cover (400) which covers the metal substrate, the sensor chip and the electrical connection assembly, where any two adjacent metal bonding pads are spaced in an insulated manner by the packaging material cover. The sensor chip package assembly has advantages of a short development period and small warpage, thus improving efficiency of subsequent assembly while saving cost. In addition, since a plurality of metal bonding pads are independent from each other on a metal substrate, independent transmission of a plurality of signals between a sensor chip and the metal substrate may be realized, thus dramatically reducing risk of interference among the plurality of signals.

There is provided a Cu bonding wire having a Pd coating layer on a surface thereof, that improves bonding reliability of a ball bonded part in a high-temperature and high-humidity environment and is suitable for on-vehicle devices. The bonding wire for a semiconductor device includes a Cu alloy core material and a Pd coating layer formed on a surface of the Cu alloy core material, and the bonding wire contains In of 0.011 to 1.2% by mass and has the Pd coating layer of a thickness of 0.015 to 0.150 µm. With this configuration, it is able to increase the bonding longevity of a ball bonded part in a high-temperature and high-humidity environment, and thus to improve the bonding reliability. When the Cu alloy core material contains one or more elements of Pt, Pd, Rh and Ni in an amount, for each element, of 0.05 to 1.2% by mass, it is able to increase the reliability of a ball bonded part in a high-temperature environment of 175°C or more. When an Au skin layer is further formed on a surface of the Pd coating layer, wedge bondability improves.

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.
