1991 - By replacing more expensive and exotic materials like gallium arsenide with silicon germanium (known as SiGe), IBM creates faster chips at lower costs. Introducing germanium into the baselayer of an otherwise all-silicon bipolar transistor allows for significant improvements in operating frequency, current, noise and power capabilities. In the 1990's alone, IBM scientists announced one semiconductor breakthrough after another: copper technology, silicon-on-insulator, silicon germanium, strained silicon, and low-k dielectrics. All of these technologies came out of IBM's fertile in-house research community. This prowess in modern chipmaking know-how didn't come out of a vacuum -- rather, it came out of the hermetically-sealed clean rooms of the most advanced R & D department in the semiconductor industry.

The History of Intel Shortly after the release of the 4004 the 8008 microcomputer was released and was capable of executing twice as many operations per second then the 4004. Intels commitment to the microprocessor led to IBM's choice of Intel's 8088 chip for the CPU of the its first PC. In 1982, Intel introduced the first 286 chip, it contained 134,000 transistors and provided around three times the performance of the other microprocessors at the time. This is the computer they used to land Apollo 13 on the moon. In 1989 the 486 processor was released that contained
