Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip. The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or ...
The Signetics 2513 [5] [6] was a character generator chip used in the TV Typewriter, [7] Apple I, and early versions of the Apple II, as well as Atari's earliest arcade games. The Signetics 82S100 FPLA (Field Programmable Logic Array) was the first commercially successful user programmable logic device , the forerunner of the modern FPGA .
Chip-on-glass (COG), a variation of COB, where a chip, typically a liquid crystal display (LCD) controller, is mounted directly on glass. Chip-on-wire (COW), a variation of COB, where a chip, typically a LED or RFID chip, is mounted directly on wire, thus making it a very thin and flexible wire.

“Rust” Director Who Survived Bullet Wound Says Resuming Filming with 'Fake Guns' Was 'Unnerving' for Alec Baldwin
Hans R. Camenzind (Swiss Standard German: [ˈkaːməntsɪnd]; 1 January 1934 – 8 August 2012 [1]) was an electronics engineer known for designing the 555 timer IC in 1971 under contract to Signetics. [2] He was the inventor on 20 US patents.
