Photo Essay Commentary

 

The Shockley 4 layer diode is truly a unique and historic device. The technology (multilayered silicon device intended to replace the transistor), the company (Shockley Semiconductor Labs, the first silicon Valley startup) and the history (Shockley’s company failed, but his stellar group of scientists and engineers went on to establish many of the world’s premier semiconductor companies) all combine to create a tremendous story and worthy subject for this Photo-Essay.
