5.2 Microsystems

5.2 Microsystems Technology There are also companies that can supply the components that are needed for the production of microsystems, such as MSG Lithoglas AG. They are engaged in research and development, production and marketing of products and procedures in the field of micro-structured materials, especially glass. They possess a unique technology which makes possible hermetic and reliable, structured glass layers with high deposition rates and low substrate temperatures. Typical applications include passivation layers, such as borosilicate glass, glass encapsulation of optoelectronic components at wafer level, as well as microfluidic elements.

KG gallery mode excitations in polymer particles with sizes in the micrometer range. Through external optical excitation, light circulates in the particles like in a spherical microscopic wave guide. The resulting interference patterns are extremely sensitive to any change in particle shape, size and the properties of the particle environment. It is even conceivable to let microprobes be eaten by living cells and to measure the biomechanical forces exerted by the cells on the probes during the process. The measurements are registered with the help of fiber-optical measuring heads and high-resolution spectrometers that NanoBioAnalytics can provide, too. The company micro resist technology develops, manufactures and sells materials for the manufacture of microelectronic and semiconductor components. Above all, it offers photoresists for optical, electron and X-ray lithography, polymers for nano-imprint lithography as well as inorganic-organic hybrid polymers for micro- and nano-optical applications. It is a distributor for Dow Electronic Materials, MicroChem Corp., and DuPont, and upon request it lithographically patterns customer substrates. Eko, however, is an optics supplier. In addition to components for recording purposes and laser optics, it also offers micro-optical components for scanning purposes, and intermediate imaging. The product portfolio of Frank Optic Products also includes microoptical components and systems. In addition to diffractive optics, Holoeye Photonics also has LCOS micro-display components on offer. LCOS stands for “Liquid Crystal on Silicon”. Here, the liquid crystal components are on a silicon chip with a highly reflective surface, combining good representation with low production costs. Monochrome and color sequential display are available.

The Berlin Nanotest und Design GmbH, for example, provides engineering services in the fields of microsystems technology and nano-technology / nano-metrology. The portfolio includes, among other things, reliability analysis for micro-components, microsystems and nanomaterials, thermal characterization of materials and microtechnological compounds, simulation of micro- and nano-structures, and the assessment of material and component arrangements of structures in the micro and nano domain. 82

5.2 Microsystems Technology The Berlin Active Space Technologies also acts as a developer of technology in the fields of aerospace, MEMS, laser and science. Active Space has expertise, inter alia, in thermal management, flow and cooling processes, mechanical and CAD development, material selection and construction of prototypes and production preparation. Among their references are the European Space Agency (ESA), Thales, and the German Aerospace Center (DLR). Another issue for microsystems technology for security purposes is product counterfeiting. To protect against plagiarism and for unambiguous identification of spare parts, they will be increasingly marked directly in the material electronically in the future. To this end, electronics must be integrated into components made of metallic or polymeric materials. In addition, they must survive adverse conditions and have a communication interface, and - ideally – their own, autonomous energy supply. Inmotec Automation specializes in automation tasks. It covers the entire range of human-machine interface, control and drive technology via EtherCAT, cam disks and complex multi-axle continuous path controls. It also has security technology in mind. The Christian Dunkel GmbH emerged from the machine tooling of the factory for television electronics, and specializes in developing, processing and manufacturing microsystems components from a variety of metals, ceramics, glass and plastics. With more than 130 employees, the company also deals with the development, production, conversion and repair of special machines, fixtures, cutting and punching tools, gauges, plastic and die-casting molds and manufacture of individual parts. Clients are mainly from the aviation and aerospace industry, power engineering, the automotive industry, optical industry and medical technology. Microsystems in security technology An important driver for the development of microsystems technology in recent years is the sharp increase in demand for technically produced security. In the region there are a number of individual actors, initiatives and networks that work specifically on this issue - more than 30 research institutions, including institutes of the Fraunhofer Gesellschaft and the Leibniz Association as well as the three major Berlin universities FU, HU and TU. The spectrum ranges from mechanical via electronic to informationtechnological security. Additionally, mechanical, medical and bioecological issues are covered. An important actor in this context is the Bundesdruckerei (Federal Printing Office). Because it also produces identity documents, it is one of its core interests to make forgery impossible. In collaboration with the Fraunhofer IZM, therefore, a multilayer security document was created with integrated electronics. The card will later determine, process and store, for example, biometric data, or even contain a flexible display on which entire image sequences could be seen. There is also the potential to couple access permissions to certain areas to the encoding of the identity card. Such a document would be extremely forgery-proof. So that the technology can be integrated into an identity document, the chips used are thinner than ten microns. In addition, such technology must also operate reliably for years no matter what trials a card is exposed to. Among other things, several thousand cycles of bending and torsion tests are designed to ensure that.

Small, mobile devices for diagnosis and therapy can assist patients 24 hours a day, without compromising the quality of life. Minimally invasive surgical techniques, possible, for example, through miniaturized cameras hardly leave a trace anymore. Even complex analyzes, which were previously done in the laboratory, can now be, in many cases, accelerated and especially carried out simultaneously using "lab on a chip" or "lab on substrates" systems. This opens many new possibilities for Berlin-Brandenburg, where medical technology is traditionally strong. Examples of companies active in this area are W.O.M. World of Medicine and MGB, both Berlin companies which produce the components for endoscopic and other minimally invasive procedures. Biotronik, once founded by the creator of the first German pacemaker, now offers pacemakers which allow simultaneous monitoring of the patient: The devices continuously transmit health data over the cellular network - worldwide and automatically, regardless of where the patient is currently located.
