Micro-wire. Coloured scanning electron micrograph (SEM) of the bonded end (grey) of a micro-wire (yellow) connected to a silicon chip. Micro-wires, often made of gold, connect the integrated circuit (multi- coloured strips) of a silicon chip to pins (not seen). These pins allow the chip to plug into a circuit board, such as found in computers. This is integrated circuit M316 S32A. Magnification: x260 at 6x7cm size.
