What PREMA Semiconductor does
PREMA Semiconductor GmbH is a privately held German analog and mixed-signal integrated circuit manufacturer headquartered in Mainz, founded in 1970 as Präzisions-Elektronik and rebranded to its present name in 2000. The company's core offering is custom Application Specific Integrated Circuits (ASICs) designed and produced exclusively for individual customers, complemented by a catalogue of Application Specific Standard Products (ASSPs) including opto-ASICs, LED drivers, high-voltage operational amplifiers, linear regulators, audio ICs, and photodiode arrays. Service revenues come from wafer-level integration of MEMS with semiconductor processes and from high-energy ion implantation services up to 6 MeV.
The business is built on PREMA's proprietary ModuS U6 bipolar and BiCMOS process, introduced in 1999, which is fabricated in-house on 150mm and 200mm wafers in an 8000 m² production facility using the SEMIC® modular cleanroom concept. The process supports supply voltages from 1V to 80V, breakdown voltages up to 135V, and current handling from the picoamp range to 1A. This vertically integrated stack spans circuit design, photomask and wafer production, and final IC test, with the company employing between 11 and 50 staff.
Revenue is generated through three streams: custom ASIC programs ranging from prototype runs to series production in the millions; standard ASSP hardware sales distributed through a global network of authorized channel partners across Europe, the Middle East, the Americas, and Asia-Pacific; and fee-for-service ion implantation and wafer-level integration work. Pricing is quote-based (EXW Mainz, 30-day terms), with direct sales-led engineering engagement used for ASIC feasibility and development, and standard products reaching smaller buyers through distributors. End markets served include industrial electronics, automotive, consumer goods, sensor technology, and selected medical and audio equipment applications.
