90 nanometer (90 nm) refers to the technology used by Intel when producing very small scale nanotechnology-based semiconductors chips from 2000-2004.
The chips had a size of 90 nm and were the smallest computer chips produced of their time.
Techopedia explains 90 nanometer (90 nm)
90 nanometer (90 nm) was a marketing buzzword to streamline all complimentary metal oxide semiconductor (CMOS) based semiconductor components and equipments having a size equivalent to 90 nm.
This name was proposed by the International Technology Roadmap for Semiconductors (ITRS). 90 nm utilizes lower k-dielectric insulators that eliminate wire-to-wire resistance, strained silicon for faster transistor switching and multiple layers of copper for improving logic density.
Some of the processors that used 90 nm technology included IBM PowerPC GF 970Fx, Intel Pentium 4 Prescott, Intel Xeon Paxville, AMD Athlon 64 Winchester and VIA- C7.
