The old „Mezon” plant was established in 1969 as a specialized high-tech microelectronic enterprise for the production of integrated circuits and consumer goods based on them. “Mezon” was subordinated to the Ministry of Electronic Industry of the USSR and was a part of NPO “Scientific Center”, Zelenograd. PO “Mezon” was one of the five largest microelectronic enterprises of the former USSR with an output of more than 130 million integrated circuits per year and was the leading microelectronic enterprise in the South-West of the former USSR and in the Balkans.

The main classes of integrated circuits produced were: logic bipolar ICs of 133, 133, 533, 1533 series; logic CMOS ICs of 561, 1561 series, analog bipolar ICs of 1092 series, RAM of 565 series, microcontrollers of 585, 1802, 1596 series, ASICs of 1828, 1854 series, EEPROM with 1.5μ technology.

This enterprise made an invaluable contribution to the exploration of space and the depths of the sea, worked for the defense industry, producing for it ultra-precise and ultra-reliable devices.

Mezon’s capacities allowed to build a complete production chain from product development to the final product, which makes it possible to independently produce a whole range of high-tech products aimed at the mass market.

Next to the plant, first a public garden and then a park gradually appeared, which the townspeople call by the same name, which has become a noun among the people.
