Kombinat Mikroelektronik Erfurt

VEB Kombinat Mikroelektronik Erfurt was an important manufacturer of active electronic components in East Germany. It should not be confused with the more well-known VEB Kombinat Robotron Dresden which used integrated circuits from Kombinat Mikroelektronik in its computers.

Their products often carried the trademark RFT, but this was used on most electronic products from East Germany from otherwise unrelated companies.

History

The Kombinat Mikroelektronik Erfurt was formed in 1978 when the VVB Bauelemente und Vakuumtechnik was split into VEB Kombinat Elektronische Bauelemente Teltow for passive electronic components and VEB Kombinat Mikroelektronik Erfurt for active electronic components. However, the history of many of the individual plants reaches back further, in some cases to before the Second World War. In 1971 the first integrated circuits had been manufactured — the D100C (TTL) by Halbleiterwerk Frankfurt (Oder) and the U101D (PMOS logic) by Funkwerk Erfurt. To put this into perspective, the first TTL circuits went into production in the US 10 years and at Siemens in West Germany 5 years before East Germany. The first microprocessor, the U808D, followed in 1978, 6 years after the Intel 8008 that the U808 was cloned from. Further milestones were the U880 (Zilog Z80 clone) in 1980 and the first 16-bit microprocessor U8000 (Zilog Z8000 clone) in 1984. The ruling Socialist Unity Party of Germany had identified the development of the microelectronics sector as a primary goal.
