1 FRAUNHOFER INSTITUTe FoR Photonic Microsystems IPMS MEMS Technologies Dresden MEMS Clean Room The Fraunhofer IPMS offers its customers a m² ( ft²) clean room equipped with state of the art tools. Its infrastructure as well as our three-shift work organization follow latest industry standards. Facilities and processes are certified for the development and fabrication of microsystems according to Class 4 per ISO , or Class 10 per U.S. standard 209E ISO 9001:2008. It allows flexible manufacturing concepts and is configured for the demands of future machine generations. Only very few MEMS foundries can go all the way from concept design to marketable products. In the field of Micro-Electro- (Opto)-Mechanical Systems (MEMS & MOEMS) the Fraunhofer Institute for Photonic Microsysstems provides foundry services for individual steps in the process or for technology modules but at the same time also covers the whole value chain from technology and product development to pilot-fabrication. Our services comprise feasibility studies, simulations of critical parameters and process flows, design, single process development and prototyping to to low/ medium volume production. These include complete electrical and nonelectrical tests and reliability examinations as well as the characterization of microsystems. Beside our know-how in the field of micro scanning mirrors and spatial light modulators we provide broad expertise in manufacturing of standard MEMS such as pressure sensors, photo diodes, ion sensitive field effect transistors and back end for IR thermopiles.

2 Services at a glance At the Fraunhofer IPMS our customers benefit from both extensive R&D and fabrication know-how and our expertise in a great variety of different fields of application. Scanning mirrors and spatial light modulators are examples for successful cooperation with industry partners. Pressure sensors for the automotive industry or photo diodes are manufactured for years in our clean room.

4 Piezo resistors Silicon frame Silicon diaphragm Pyrex glass with drill hole Bond surface Manufacturing Technologies Fraunhofer IPMS develops for its customers micro-electromechanical systems (MEMS) and micro-optoelectromechanical systems (MOEMS), products and technologies. In these growing fields of technology we use our existing technological capabilities for bulk MEMS, surface MEMS and the monolithic integration of CMOS and MEMS/MOEMS. Our work is performed in a state-of-the-art MEMS clean room, capable of handling 150 mm wafers. Bulk Micromachining With bulk micromachining we create threedimensional structures out of the single crystalline silicon substrate (the bulk) of the wafer. These structures are trenches, bars, membranes etc., moveable and electrically isolated. The wafer front side is processed with CMOS compatible processes, the backside of the wafer will be processed and structured as well. The position of the backside structures have to be aligned to the front side in order to release the bulk structures. Our front side key process is DSE (deep silicon etch) - the so-called Bosch process. On the backside we master the wet KOH or TMAH etch as well as the DSE process. As a result cavities are generated on the backside and the structures on the Surface Micromachining In surface micromachining we generate structures on the surface of the wafer. This allows the monolithic integration of a CMOS device (which we process first) and after that an actor or sensor is fabricated on top of the CMOS layer. Moveable parts are created by depositing the sensor/actuator material on top of a sacrificial layer, which is later to be removed (sacrificial etch) in order to release the actor/ sensor structures. With the implementation of inorganic sacrificial layers (amorphous silicon or SiO 2 ) we are going towards standardization of MEMS technologies in this field. Therefore compatibility is increased and more complex structures are possible. front side are released.
