Silicon Alley Silicon Alley Silicon Alley, centered around the Flatiron district in Manhattan, is an area of high tech industries. The term was coined in the 1990s during the dot-com boom, as a reference to <nowiki>"Silicon Valley", the tech center in California. As the New York tech industries began a revival around 2003, the businesses spread outside of Manhattan making the term 'Silicon Alley'</nowiki> somewhat obsolete. , New York City hosted 300,000 employees in the tech sector. In 2015, New York generated over US$7.3 billion in venture capital investment. High technology startup companies and employment are growing in New York City 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
