context_page_description: Silicon Valley is the southern part of the San Francisco Bay Area in California in the United States. The term originally meant the innovators and manufacturers of silicon chip who worked here, but now means all the high tech businesses in the area. Even though it's not truly a valley, it is a term for the high-tech sector generally.
  Silicon Valley includes the northern part of Santa Clara Valley and adjacent communities in the southern parts of the San Francisco Peninsula and East Bay. It reaches from Menlo Park and the Fremont/Newark area in the East Bay down to San Jose.
