caption_attribution_description: English: A sculpture representing a Shockley 4-layer diode, on the sidewalk in front of the new building at 391 San Antonio Rd., Mountain View, CA, which was the original site of the Shockley Semiconductor Laboratories where the first silicon device work in Silicon Valley was done.
context_page_description: The Shockley diode is a four-layer semiconductor diode, which was one of the first semiconductor devices invented. It is a PNPN diode, with alternating layers of P-type and N-type material. It is equivalent to a thyristor with a disconnected gate. Shockley Diodes were manufactured and marketed by Shockley Semiconductor Laboratory in the late 1950s. The Shockley diode has a negative resistance characteristic.
