The history of the company is closely related to Cegléd city. 

In 1989 TET (Power Electronics Equitable Company) included the following companies: CVEM (Cegléd Iron-, Electronic- and Instrument Industrial Co-operative), VKI (Electrical Industry Research Institute) and Mercator (AEG Hungarian subsidiary). The TET started the production of bipolar discs and modules with assembly and testing according to a licence which was bought from AEG.

On the basis of AEG semi-conductor manufacturing centre, eupec GmbH was founded next year in Warstein, Germany. This company is 100 % owned by Siemens from 1995. EupecHungary Ltd. carried on the semi-conductor assembly production, which was started by TET, from November 1996 as a 100% subsidiary of the eupec Germany.

Before 1996 1 million semi-conductor power modules were produced in Cegléd moreover a dynamic development started with the foundation of the individual company.

The Infineon Technologies AG was founded in 2000, originated from the Siemens semiconductor division. In the same year, the facility and the production area was purchased from CVEM in Hungary.

In 2001 the site was restructured within the New BIP Project, therefore the whole bipolar pressure-contact products assembly and testing were made by Cegléd.

IGBT (Insulated Gate Bipolar Transistor) assembly and production was started from 2002. During the runner up, the first 2 storey production area with 4500 m² was build establishing 300 new workplaces and the production activity launched in January 2004. Due to the project a high-tech infrastructure, which was unique in Hungary, located in Cegléd and it was supported by the European Union and the local Government. Thanks for the well qualified young specialists and the professional support of the German colleagues, the project was successful.

Infineon AG integrated the Hungarian subsidiary in 2005.

According to the 2 main product types from October 2007, the Cegléd site in Hungary shared by Infineon Technologies Cegléd Ltd – which produces IGBT modules - and Infineon Technologies Bipolar Ltd - which produces bipolar semi-conductor modules and discs.

Infineon Technologies expanded its semi-conductor manufacturing in 2009 by investing more than 10 million euro to buildings and manufacturing equipments in Cegléd, Hungary. In the near future Infineon doubled the volume of modules based on IGBT semiconductor devices and increased the production more than 6 million pieces by year.

Since the foundation of the company, the Infineon's expanding strategic capacity and skills development fits into the priority objectives of the Hungarian economic development. The success of the company's projects was contributed by the winning central governmental supports so far:

• GFC (Economic Development Target), 2000-2001
• SMART-Hungary , 2003-2004
• GVOP (Economic Competitiveness Operational Program), 2005-2006
• EKD (tender for financial support granted by Individual Government Decision), 2008-2011
• KMOP (Central-Hungarian Operative Program), 2008-2010

The foundation of the reliability of our products is our quality. We follow our Zero Defect mindset which supports us to reach the lowest level of failure rate. This Zero Defect mindset enhances quality awareness and focus on fulfillment of the customer requirements. The international recognition for Excellent Quality Management on Fabrik des Jahres in 2014 shows our commitment toward high quality standard.

Our commitment to quality was recognized also inside Infineon group and our Cegléd location received a good opportunity for growths with the manufacturing of a new product family in Cegléd. This product is called IHM (IGBT High-power Module), which includes the most well known products of Infineon on the high power semiconductor market. Now our location can prove ourselves on this new, challenging segment of the world wide semiconductor market as well.

As a global demand for energy expand, the continuously increased the production types. Cegléd plant primarily produces standard power modules, which are key components used in wind turbines and solar inverters for photovoltaic systems, as well as in locomotive drives, streetcars, manufacturing plants, escalators and elevators.

Our company successfully was certified according to the automotive quality management system standard ISO/TS 16949 and the environmental management ISO 14001 standard. Our commitment toward work safety and health is proven with OHSAS 18001 certification. Most recently, in year 2016 we have received our energy management ISO50001 certificate.

Due to the constant development of the site in the last 27 years, the once (1989) small factory with 37 employee had been grown into a dynamically growing, leading company of the area with about 1000 employee, and with the yearly output of over 8,5 million semiconductor modules.
