Abstract

Traditional mask-beginning design flow of micro device is unintuitive and fussy for designers. A hierarchical design method and involved key technologies for features mapping procedure are presented. With the feature-based design framework, the model of micro device is organized by various features in different designing stages, which can be converted into each other based on the mapping rules. The feature technology is the foundation of the three-level design flow that provides a more efficient design way. In system level, functional features provide the top level of schematic and functional description. After the functional mapping procedure, on the other hand, parametric design features construct the 3D model of micro device in device level, which is based on Hybird Model representation. By means of constraint features, the corresponding revision rules are applied to the rough model to optimize the original structure. As a result, the model reconstruction algorithm makes benefit for the model revision and constraint features mapping process. Moreover, the formulating description of manufacturing features derivation provides the automatic way for model conversion. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2490

Abstract

The micro device designing flow begins with the mask design currently, which is not intuitive for designer and sometime made them confused. As a result, the manufacturability is hard to prove in advance with the traditional designing way. Especially for surface micro-machined device with multiple structural layers, the 2D mask design cannot ensure the fabrication of complex 3D device with high yields reliably. The rise of structural designing strategies gave a direction to change the traditional habit. On the other hand, the top-down method provides the advanced designing flow, which begins with the system level design. However, there still some key technologies to study further because of the novel design procedure. To improve the manufacturability of micro device, the designing flow based on design for manufacturability methodology is presented, which draw on the advantages and experience of the mechanical design method. The key technologies on the structural design level, the processes planning level and the fabricating level are introduced correspondingly. In addition, we present the framework to implement the method. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3081
