SÜSS MicroTec AG is a supplier of equipment and process solutions for the semiconductor industry and related markets. The high precision microstructuring systems like photolithography tools are used for manufacturing of processors, memory chips, MEMS, LED and other micro system devices. SUSS MicroTec is headquartered in Garching bei München, Germany. In 1949, Karl Süss founded the company Karl Süss KG to support sales and service for optical devices made by Ernst-Leitz GmbH, later Leica, in Munich, Germany. Then in 1963 the assignment by Siemens to develop a simple photolithography tool marked a change in the strategic direction of the company towards contract manufacturing and engineering. With the creation of the MJB3, the first mask aligner now exhibited in the Deutsches Museum in Munich, the company entered the emerging semiconductor industry. In addition to manual and automatic alignment equipment the product portfolio extended to systems for related wafer processing steps such as development, cleaning and wafer bonding. The company expanded into the global market with the foundation of its first overseas subsidiaries in the 1980s.
