The main characteristic and main advantage of the new methodology is that the 1D and multi-dimensional objects or domain are meshed completely independently of each other, without regard to their relative alignment or location, and subsequently combined into a single, unified composite mesh. The coupling of the solution between the different domains is handled fully-automatically in the solver, entirely through exchange of source terms between these domains of differing dimensionality. The source terms are evaluated locally on a cell-by-cell basis, depending on the solution values in these domains and the manner in which the 1D grids intersect the multi-dimensional grids. The capabilities and usefulness of the method are demonstrated with several examples.","PeriodicalId":318748,"journal":{"name":"Design, Test, Integration, and Packaging of MEMS/MOEMS","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129238142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, the design of an electronic component requires many competencies and skills, and the joint effort of several researchers and engineers, not necessarily located a the same lace. With traditional ways of work and communication tools, the interactivity level is reduced and it seems that the product life cycle cannot be improved significantly anymore. As a response, the technological progress in high speed networks and new communication and interaction tools open the way to concurrent engineering. This paper then aims at presenting such way of working, the new functionalities provided to users, and of course the benefits they can gain.

The design of such integrated system will occur at the system level, driven primarily by the application. Methodologies that ease the integration of the digital domain to the real world using mixed domain technologies are therefore crucial. A hierarchical structured design approach that is compatible with standard IC design is outlined. It starts with schematic capture of a design topology, followed by behavioral simulation, layout generation, parasitic extraction, and final verification. This flow is based on a process-independent design representation of commonly used MEMS building blocks, and process-dependent materials properties, design rules, and parasitic parameters.","PeriodicalId":318748,"journal":{"name":"Design, Test, Integration, and Packaging of MEMS/MOEMS","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114253446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The core part of the scanner is formed by vertical bimorph beams, which are reported for the first time in this paper. They consist of silicon beams side-coated with aluminium, which bend upon heating causing movement in the horizontal plane. Combining vertical bimorphs with planar bimorphs allows three-dimensional actuation. Theoretical analyses comprising electro-thermal and thermo-eleastic calculations show that large actuation movements are possible at low electrical input power and low input voltage. A process has been developed to deposit aluminium onto sidewalls of silicon beams. Furthermore, the fabrication process for the actuator is described.","PeriodicalId":318748,"journal":{"name":"Design, Test, Integration, and Packaging of MEMS/MOEMS","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130640870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
