Silicon Alley build a US$2 billion graduate school of applied sciences on Roosevelt Island, with the goal of transforming New York City into the world's premier technology capital. As of 2013, Google's second largest office is located in New York. Verizon Communications, headquartered at 140 West Street in Lower Manhattan, was in 2014 in the final stages of completing a US$3 billion fiberoptic telecommunications upgrade throughout New York City. This revival was not restricted to Lower Manhattan, but was spread throughout New York City. Hence "Silicon Alley" has been considered by some observers to be an obsolete term.

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
