New York City is the largest central business district in the world. Silicon Alley, centered in Manhattan, has evolved into a metonym for the sphere encompassing the New York City metropolitan region's high technology industries involving 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 its entrepreneurship ecosystem and venture capital investments. In 2015, Silicon Alley generated over US$7.3 billion in venture capital investment across a broad spectrum of high technology enterprises, most based in Manhattan, with others in Brooklyn, Queens, and elsewhere in the region. High
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
