The bank also has the largest gold repository in the world, larger even than Fort Knox. Its vault is 80 feet (25 m) beneath the street and holds $160 billion worth of gold bullion. Silicon Alley, centered in Manhattan, has evolved into a metonym for the sphere encompassing the New York City metropolitan region's high tech enterprises involving the Internet, new media, telecommunications, digital media, software development, biotechnology, game design, and other fields within information technology that are
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
