The Department of Computer Sciences and Microsystems Technology, and the research focus area "Integrated Miniaturized Systems" (IMS) require a system for physical vapor deposition (PVD) to research modern micro- and nanosystems. The IMS research focus area (www.hs-kl.de/ims) is very successful and conducts numerous, mainly third-party funded, research projects, with high quality scientific publications. A particular research focus is on interdisciplinary projects at the interface of life sciences and microsystems technology, developing, for example, novel biosensors, electrode arrays and electrophysiological measurement systems. To manufacture such systems, the PVD applied for is needed as a central component of a fabrication process chain in the clean room. The procurement is urgently required because the currently available system can only be used to a limited extent due to the age of the equipment and its inability to be repaired. PVD is particularly suitable for depositing very thin layers, up to partial monolayers, especially of electrically conductive metals, on a substrate. These layers have excellent quality and homogeneity, meeting the requirements of demanding microsystems research. PVD is an established process in microsystems technology and is used in particular to produce electrodes and conductive tracks, e.g. for biosensors or electrode arrays for deriving neuronal or other electrophysiological signals from individual cells or tissues. The combination of different material classes enables the production and research of novel sensor systems. For example, in the field of biosensors, graphene and other nanomaterials now play an important role, requiring metallic leads made of gold or platinum. In the field of magnetic sensors, complex layer systems of iron, nickel, cobalt and molybdenum are increasingly being used. A versatile PVD system is needed to deposit these different materials. In particular, for the deposition of high-density and low-defect coatings, the system requires an electron beam evaporation source with sources that can be changed under vacuum. For fast deposition of thicker coatings, additional sources for thermal deposition are needed. By using this system for the fabrication of novel micro- and nanostructures, we expect a high gain in knowledge in the context of ongoing and planned research projects. The PVD system is an important link in a process chain in the clean room and will be complemented by other existing equipment on site. The department has many years of experience in the operation of cleanroom facilities. All personnel and infrastructure requirements for operating the tool are already in place at the site.

计算机科学和微系统技术系以及研究重点领域“集成微型系统”（IMS）需要一个物理气相沉积（PVD）系统来研究现代微系统和纳米系统。IMS研究重点领域（www.hs-kl.de/ims）非常成功，开展了许多主要由第三方资助的研究项目，并发表了高质量的科学出版物。一个特别的研究重点是在生命科学和微系统技术的接口跨学科项目，开发，例如，新的生物传感器，电极阵列和电生理测量系统。为了制造这样的系统，需要将所应用的PVD作为洁净室中制造工艺链的中心组件。之所以迫切需要采购，是因为现有系统由于设备老化和无法修理，只能有限地使用。 PVD特别适合于在衬底上沉积非常薄的层，直到部分单层，特别是导电金属的层。这些层具有优异的质量和均匀性，满足了苛刻的微系统研究的要求。PVD是微系统技术中的既定工艺，并且特别用于生产电极和导电轨道，例如用于生物传感器或电极阵列，以从个体细胞或组织获得神经元或其他电生理信号。不同材料类别的组合使新型传感器系统的生产和研究成为可能。例如，在生物传感器领域，石墨烯和其他纳米材料现在发挥着重要作用，需要由金或铂制成的金属引线。在磁传感器领域，铁、镍、钴和钼的复杂层系统越来越多地被使用。需要多功能PVD系统来存款这些不同的材料。特别地，对于高密度和低缺陷涂层的沉积，该系统需要具有可以在真空下改变的源的电子束蒸发源。为了快速沉积较厚的涂层，需要额外的热沉积源。 通过使用该系统制造新颖的微米和纳米结构，我们期望在正在进行的和计划的研究项目的背景下获得很高的知识。PVD系统是洁净室工艺链中的重要环节，将与现场其他现有设备相辅相成。该部门在洁净室设施的操作方面拥有多年的经验。操作该工具所需的所有人员和基础设施都已在现场到位。
