Integrated circuit ('IC') unit and a wafer for fabricating IC units. The wafer has a first surface and a second surface opposite to the first surface. A redistribution metal layer may be formed on the first surface and may be patterned to have a redistribution metal layer pattern. A backside metal layer may be formed on the second surface and patterned to have a backside metal layer pattern so that the backside metal layer may be adapted to generate a backside stress on the wafer to at least partially offset a front side stress generated by the redistribution metal layer on the wafer.

The disclosure concerns oil drilling technology, and specifically an all-metal intelligent control motor (AMIM). The AMIM comprises an electric control module, a power module and a transmission module. The electric control module determines the axial position of the connecting rod valve through an electromagnet and controls the connection between the connecting rod valve and the piston through an electric motor. The hydraulic pressure of drilling fluid and the spring reaction force in the power module push a double worm to move axially and circumferentially under the action of internal teeth on the inner surface of shell. A one-way bearing ensures that the power module only transmits unidirectional motion. The transmission module axially limits the power module through TC bearings and transmits circumferential motion, drilling pressure and torque to the lower drilling tool. The AMIM is suitable for all kinds of deep well exploration, with a stronger drilling force, a lower cost and a higher applicability.

A LED driving system for driving a LED matrix. The LED driving system includes an interconnection structure having a first surface and a second surface opposite to the first surface and a plurality of driver dies/chips attached to the first surface of the interconnection structure. The LED matrix is divided into a plurality of sub LED matrix sections that are attached to the second surface of the interconnection structure. The interconnection structure is configured to electrically couple each one of the plurality of sub LED matrix sections to a corresponding one driver die/chip in the plurality of driver dies/chips.
