Current portfolio

Bosch manufactures and sells electronic components for vehicles and for consumer electronics. These include application-specific integrated circuits (ASICs), power semiconductors and microelectro-mechanical systems (MEMS) such as acceleration, pressure, yaw-rate, magnetic field, mass-flow and environ-mental sensors.

Manufacturing sites

  • Reutlingen (150-mm and 200-mm technology)
  • Dresden (300-mm technology)

Patents

Bosch holds more than 1,000 patents and patent applications for MEMS technology as well as more than 500 in the field of semiconductor technology.

Market

The requirements after semiconductor chips (ASICs, power semiconductors and MEMS) will further increase. The reason is about a rise of the proportion of semiconductors in electronic devices and car applications, e.g. connected and automated driving or the electro mobility. Microelectronics can be seen as technological key sector.

Expertise in innovation and technology

Invented for life

For more than 60 years Bosch has been developing and manufacturing microelectronic components and systems. In 1958 the first semiconductor product a “Variode” was produced in Stuttgart-Feuerbach. Semi-conductors (integrated circuits) have been manufactured at the wafer fab in Reutlingen since 1970.

Know-How in semiconductor’s business

Microelectronics: Bosch is making key business Technologies accessible and is inventing innovative production measures. The company developed the microfabrication technique called “Bosch Prozess” in 1994 where new semiconductors can be manufactured.

Sensor technology

Since 1995 Bosch has been producing more than 15 billion MEMS and is now the world market leader in this field.

“Deutscher Zukunftspreis 2008“

Award winning invention of a new procedure for the surface micromechanics.

First AIot-plant in Dresden

In 2021 Bosch opened one of the most modern wafer fab in the world: a highly automated and intelligent plant, with fully connected machines and embedded processes combined with artificial intelligence methods.

New innovation in series

At the end of 2021: start of production of Silicon carbide (SiC) semiconductors which are used in the power electronics of electric cars reaching more range and faster charging stops.

Vertical synergies

Bosch is one of the leading suppliers in the automotive industry with an own sector for semiconductors.

Investments

Capital expenditure

In its wafer fabs in Reutlingen and Dresden alone, Bosch has invested more than 2.5 billion euros since 200-millimeter technology was introduced in 2010. On top of this, billions of euros have been invested in developing microelectronics.

2021

The wafer fab Dresden is the biggest single Investment of the company’s history with about one billion euros of investment. Till 2023 in Reutlingen: more than 150 million euros will be invested for new cleanroom surface areas in existing buildings and 150 new jobs in the fields of semiconductor development will be raised.

2022

More cleanroom surface areas for meeting the demand of chips: more than 400 million euros for the expansion in Dresden, Reutlingen, Penang.

2023

Expansion of the existing cleanroom surface area in Dresden for more than 250 million euros.

Till end of 2025

State-of-the-art manufacturing: more than 250 million euros will be invested for a new element, the total amount of the cleanroom surface area will raise up to 44,000 m².

Mobility is the largest Bosch Group business sector. According to preliminary figures, it generated sales of 56.3 billion euros in 2023, and thus contributed almost 60 percent of total sales.
