The digital output circuit contains a system-side driving circuit, an electromagnetic coupling device, and an output-side control circuit. The electromagnetic coupling device contains at least a system-side electromagnetic coupling element, a first output-side electromagnetic coupling element, and a second output-side electromagnetic coupling element. The system-side driving circuit is connected to the system-side electromagnetic coupling element, and takes the ON/OFF digital control signals from the digital system as input to turn on and off its driving to the system-side electromagnetic coupling element. The electromagnetic coupling device converts and transmits the electrical energy from the system side to the output side and thereby provides the working energy to and required by the output control circuit connected to the first output-side electromagnetic coupling element. The second output-side electromagnetic coupling element forms a feedback circuit, through which the electrical status at the output side is fed back to the system side via the electromagnetic coupling device.

摘要： MEMS processes for fabrication of a MEMS alloy probe are revealed. Multiple layers of the MEMS alloy probe are formed on the substrate in sequences as a first surface layer, a first conductive layer, a core layer, a second conductive layer, and a second surface layer where the width of the first conductive layer is smaller than the one of first surface layer so that all the exposed edges of the first surface layer are not covered by the first conductive layer. The second surface layer is extended from the sidewalls of the core layer to the exposed edges of the first surface layer to encapsulate the core layer, the first conductive layer, and the second conductive layer. The MEMS alloy probe fabricated by the MEMS processes can eliminate the issue of oxidation.

摘要： A method of forming a plurality of elastic probes in a row is disclosed. Firstly, a substrate is provided, then, a shaping layer is formed on the substrate so as to offer two flat surfaces in parallel. A photoresist layer is formed on the substrate and on the shaping layer. Then, the photoresist layer is patterned to form a plurality of slots crossing an interface between the two flat surfaces where a plurality of elastic probes are formed in the slots. In one embodiment, the interface is an edge slope of the shaping layer so that each of the elastic probes has at least an elastic bending portion. During chip probing, the shifting direction of the elastic probes due to overdrives is perpendicular to the arranging direction of the bonding pads so that the elastic probes are suitable for probing chips with high-density and fine-pitch bonding pads.
