Manhattan evolved into a metonym for the sphere encompassing the New York City metropolitan region's high tech industries, including the Internet, new media, telecommunications, digital media, software development, biotechnology, game design, financial technology ("fintech"), and other fields within information technology that are supported by the area's entrepreneurship ecosystem and venture capital investments. , New York City hosted 300,000 employees in the tech sector. In 2015, Silicon Alley generated over US$7.3 billion in venture capital investment, most based in Manhattan, as well as in Brooklyn, Queens, and elsewhere in the region. High technology startup companies and employment are growing in Manhattan and
Silicon polymers, elastomers, and resins. In the late 20th century, the complexity of the crystal chemistry of silicides was mapped, along with the solid-state chemistry of doped semiconductors. Because silicon is an important element in high-technology semiconductor devices, many places in the world bear its name. For example, Santa Clara Valley in California acquired the nickname Silicon Valley, as the element is the base material in the semiconductor industry there. Since then, many other places have been dubbed similarly, including Silicon Forest in Oregon, Silicon Hills in Austin, Texas, Silicon Slopes in Salt Lake City, Utah, Silicon Saxony in Germany, Silicon
