The name also became a global synonym for leading high-tech research and enterprises, and thus inspired similar named locations, as well as research parks and technology centers with a comparable structure all around the world.
Governmental planners and business networks like to use the name "silicon" or "valley" to describe their own areas as a result of the success of Silicon Valley in California.

Santa Clara County, California

Santa Clara CountySanta ClaraCounty of Santa Clara
As more high-tech companies were established across San Jose and the Santa Clara Valley, and then north towards the Bay Area's two other major cities, San Francisco and Oakland, the "Silicon Valley" has come to have two definitions: a geographic one, referring to Santa Clara County, and a metonymical one, referring to all high-tech businesses in the Bay Area.
Home to Silicon Valley, Santa Clara County is a global economic center for high technology and has the third highest GDP per capita in the world (after Zurich, Switzerland and Oslo, Norway), according to the Brookings Institution.

Mountain View, California

Mountain ViewMountain View, CaliforniaMountain View, CA
Other major SV cities include Palo Alto, Santa Clara, Mountain View, and Sunnyvale. In 1956, William Shockley, the creator of the transistor, moved from New Jersey to Mountain View, California, to start Shockley Semiconductor Laboratory to live closer to his ailing mother in Palo Alto.
In 1956, Shockley Semiconductor Laboratory, the first company to develop silicon semiconductor devices in what came to be known as Silicon Valley, was established in the city by William Shockley.

Stanford University

William Eitel, Jack McCullough, and Charles Litton, who together pioneered vacuum tube manufacturing in the Bay Area, were hobbyists with training in technology gained locally who participated in development of shortwave radio by the ham radio hobby.
Charles Vincent Litton Sr. (1904–1972) was an engineer and inventor from the area now known as Silicon Valley.

California

In 1956, William Shockley, the creator of the transistor, moved from New Jersey to Mountain View, California, to start Shockley Semiconductor Laboratory to live closer to his ailing mother in Palo Alto.
Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s led to California's "Silicon Valley" becoming a hotbed of electronics innovation.

Northern California

Silicon Valley (abbreviated as SV) is a region in the southern San Francisco Bay Area of Northern California, referring to the Santa Clara Valley, which serves as the global center for high technology, innovation and social media.
Its economy is diverse, though more concentrated in high technology, and subject to the whims of venture capital than any other major regional economy in the nation especially within Silicon Valley, and less dependent on oil and residential housing than Southern California.

Frederick Terman

During the 1940s and 1950s, Frederick Terman, as Stanford's dean of engineering and provost, encouraged faculty and graduates to start their own companies.
He is widely credited (together with William Shockley) as being the father of Silicon Valley.

Electronic News

Electronic News Weekly
Hoefler used the phrase as the title of a series of articles in the weekly trade newspaper Electronic News.
This is thought to be the first published use of the phrase Silicon Valley to describe the area of the southern part of the San Francisco Bay area in northern California, United States, an area known for its concentration of companies making semiconductors, among them Intel, LSI Logic, National Semiconductor.

In 1933, Air Base Sunnyvale, California, was commissioned by the United States Government for use as a Naval Air Station (NAS) to house the airship USS Macon in Hangar One.
The massive hangar has long been one of the most recognizable landmarks of California's Silicon Valley.

Silicon

The word "silicon" originally referred to the large number of silicon chip innovators and manufacturers in the region, but the area is now the home to many of the world's largest high-tech corporations, including the headquarters of 39 businesses in the Fortune 1000, and thousands of startup companies.
For example, Santa Clara Valley in California acquired the nickname Silicon Valley since the element is the base material used in the semiconductor industry located there.
