LM of 3 memory silicon chips
Light micrograph showing the junction of 3 memory silicon chips & a test module (top) on a manufac- tured wafer. Chips are made on thin, circular, silicon wafers 7.5cm in diameter. Each wafer forms a substrate on which about 100 chips are made by a series of coating & etching processes that build up the chips complex circuitry. Electronic probes are lowered onto the test modules square pads for quality control testing. The chips are cut from the wafer by running a diamond knife along the green bands between each chip. The 16K 4116 chips in this micrograph are typical memory chips used in computers & other electronic equipment. Mganif- ication: x20 at 35mm size, x40 at 6x7cm size.

EDITORS COMMENTS
This print showcases the intricate beauty of three memory silicon chips, captured under a light microscope. The image reveals the junction where these chips meet a test module on a manufactured wafer. These chips are meticulously crafted on thin, circular silicon wafers measuring 7.5cm in diameter. The manufacturing process involves a series of coating and etching techniques that gradually build up the complex circuitry within each chip. To ensure quality control, electronic probes delicately descend onto the square pads of the test modules for testing purposes. To separate each individual chip from the wafer, a diamond knife is carefully run along the green bands between them. In this particular micrograph, we can observe 16K 4116 memory chips commonly utilized in computers and various electronic devices. At magnifications of x20 for 35mm size and x40 for 6x7cm size, this image offers an extraordinary glimpse into the world of integrated circuits and electronics. It serves as a testament to human ingenuity and technological advancement in creating these essential components that power our modern digital age. This remarkable photograph is sourced from Science Photo Library's publication "MICROCOSMOS" specifically figure 8.20 on page 160 – an invaluable resource for anyone fascinated by electronic technology and its microscopic wonders.
