The First Transistor
New York Times
“A device called a transistor, which has several applications in radio where a vacuum tube ordinarily is employed, was demonstrated for the first time yesterday at Bell Telephone Laboratories, 463 West Street, where it was invented.”
23rd December 1947

The First Integrated Circuit
1958, Jack Kilby, a young electrical engineer at Texas Instruments, figured out how to put all the circuit elements - transistors, resistors, and capacitors, along with their interconnecting wiring - into a single piece of germanium.
His rough prototype was a thin piece of germanium about one-half inch long containing five separate components linked together by tiny wires.
The Microprocessor
4004: Intel’s first microprocessor
The speed of this 1971 device was estimated at 0.06 MIPS (million instructions/s).
By comparison, in 2000 Intel's Pentium ran at 133 MHz, contained 5.5 million transistors, & could execute 300 MIPS. Complexity & speed have risen steadily since then!
The 4-bit 4004 ran at 108 kHz & contained 2300 transistors.
Intel 8086/8088 and IBM PC
1978: 8086/8088 Microprocessor
A pivotal sale to IBM’s new personal computer division made the 8088 the brains of IBM’s new ‘hit product’ -- the IBM PC.
This was followed in 1982 by the 80286, on which was based the IBM PC/AT (Advanced Technology) computer.
Intel 80386 and 80486
The Intel ‘386 (1985) contained 275,000 transistors. It was Intel’s first ‘32-bit’ chip, and was capable of ‘multi-tasking’.
The ‘486 (1989, shown) was significantly more powerful, and was the first to offer a built-in math. co-processor, greatly speeding up transcendental functions.
Intel Pentium
The Pentium was first introduced in 1993 - it was designed to allow computers to handle “real-world” data such as speech, sound and images.
The latest Pentium II (1997) contained 7.5 million transistors, and is packaged in a unique format.
Scaling - Intel Pentium Origin design used MOSFETs with L=0.8 m
Speed limited to fclk= 66 MHz
Shrink minimum dimension to 0.6 m Raise clock to 100 MHz - 50% more throughput Lower power consumption Latest P4 uses L=0.09 m fclk=3800MHz (internal)!

The billion-transistor chip is imminent!
