The TEM Module is fully coupled with IntelliSuite’s PiezoMEMS module, the most sophisticated piezoelectric and piezoresistive modeling tool in the industry. Considering piezo actuation for your MEMS device? You can investigate the voltage dependency of the natural frequency, calculate the Q factors in different packaging environments, or apply time-varying loads with ease. You can also look at a floating conductor voltage as a function of time-varying loading, an important factor in acoustic transducer and microphone design. IntelliSuite is the only tool on the market to offer fully-coupled linear and non-linear thermal-electrostatic-electromagnetic-mechanical simulations. TEM coupled with the ElectroMagnetic module can be used to simulate static and frequency responses of magnetic or electromagnetically actuated MEMS devices. Lorentz force-driven actuators such as scanning mirrors, switches, and mechanisms can be simulated wth ease. TEM is also fully coupled with IntelliSuite’s Microfluidic module. With the capability to analyze advanced fluid-structure interaction, IntelliSuite makes it easier than ever to model complex devices like piezoelectrically-actuated micropumps, fluidic damping in large micromirror arrays, and micromechanical valves.

Wake up and smell the coffee… Design analysts spend a significant amount of time manipulating design geometries and meshing structures. Most MEMS design tools require manually partitioning 3D geometry into mesh-able regions. Studies have shown that in a typical 10-step design through analysis cycle, a staggering 73% of time is spent in geometry manipulation and meshing Design through analysis man-hours spent (not CPU hours). A typical 10-step design through analysis cycle (excluding iterations) is shown. A staggering 73% of time is spent in geometry manipulation for meshing. [Courtesy: Matt Staten, Computing and Modeling Dept, Sandia National Labs] While many tools provide automated tetrahedral(tet) meshes they are suboptimal for MEMS design. In the words of a Sandia Labs design analyst, “The only people who use tets are those who don’t care about their answers”. Hexahedral meshes are ideal for MEMS. However, automatic generation of hex meshes for complex MEMS structures has been a big challenge … until now Top features - AutoMeshing Hexpresso takes you from process flow, schematic or layout to hex mesh in one click! - Mesh Morphing morphs the mesh to make quick changes, without having to remesh - Defeature Exclude unnecessary details (dimples, for instance) and simplify polygons before meshing - Mesh Refinement Specify areas of mesh refinement.

AnisE is an easy-to-use anisotropic etch process simulation tool for MEMS design and process control Demystifying etch behavior Anisotropic etching is one of the most difficult silicon micro-machining processes to model, often considered in the realm of the black arts. It can be challenging to grasp intuitively due to the complex nature of evolving etch fronts. In fact, many companies have developed closely guarded etch secrets through trial-and-error experimentation. Well, those days have ended. AnisE simplifies the process of accurately simulating etch behavior. Import your mask, choose your wafer orientation and your process parameters, and then watch the etching progress online before your eyes! Cellular automata Unlike other tools that utilize heuristic methods to calculate propagation of etch planes, AnisE is a cellular automata based simulation. What does this mean? That other tools fail to provide accurate results for complex masks and long etch times. With AnisE, you can choose any mask configuration, however complex, throw in double-sided etching and add etch stops. Its easy AnisE at work 3D evolution of Silicon etch profiles generated by AnisE are shown in three cases. (a) evolution of three different corner compensation schemes (b) double-sided etching of a silicon boss for an accelerometer application and (c) multi-etch of silicon, an example where DRIE is followed by an anisotropic etch. Sophisticated controls AnisE comes with built-in etch databases for KOH and TMAH. It automatically updates the etch rates as a function of temperature and concentration. With AnisE, you can simulate single or double-sided <100 and <110 etching. You can incorporate multiple etch stops, steps or anything else you can do in the real world. In addition, you can study the effect of mask misalignment, the effect of combining RIE etching with anisotropic etching and many other real- world conditions. Whether you are interested in studying process variation or designing corner compensation features, AnisE will become an invaluable part of your process toolset. Comprehensive Capabilities AnisE is capable of predicting the effects of etchant temperature, concentration, and etch time on the final 3D device geometry. Corner compensation and process tolerances can be modeled and visualized with AnisE. Creating correct geometries based on proper etch parameters before entering a fabrication facility saves resources otherwise spent on multiple prototype iterations. Top features By creating or importing a mask file, users can: - Simulate <100 or <110 wafer orientation etching - Simulate etching under different time, temperature, and concentration parameters - Access TMAH and KOH etch-rate databases, or use customized etch-rate data - Etch the top, bottom, or both sides of a wafer - Implement multiple protective etch stops - Perform multiple etchings with different masks on a single wafer - Study the effects of misalignments and other process deviations - Determine the effects of vertical etching coupled with anisotropic etching - Perform 3D geometric visualization and cross-sectioning - Take distance measurements on the etched wafer - Visualize and export 3D results in DXF and VRML formats

IntelliFAB allows you to debug your process flow and your mask set even before you enter the clean room. It allows you to make virtual prototypes to save costly fabrication mistakes. Welcome to your virtual fab Until now, MEMS designers have typically focused purely on geometric representation of the device in order to analyze device behavior. The drawback of this methodology is that process induced effects may vary the geometry of the structure significantly. For example, the boron diffusion as an etching stop layer for bulk silicon processing may overstress the structure, strain gradients in poly-silicon structures can distort features, or an anodic bonding process may break down protective oxide films. IntelliFAB allows designers to takes a different approach. Process flow forms the basis of creating your devices. Our comprehensive process simulation modules incorporate deposition, etching, bonding, doping, electroplating, liftoff, and other process steps common in MEMS design. Other process-induced effects, such as micro-assembly, are also addressed to generate accurate geometric models for the complete range of MEMS devices. IntelliFAB is directly linked with MEMaterial, a MEMS process database that stores material properties as a function of your machine settings. By developing the fabrication process in conjunction with the analysis model, IntelliSuite enables engineers to perform more accurate device physics analysis and produce manufacturable devices faster. MEMS Process Editor A typical MEMS process flow can consist of hundreds of process steps which need to be cataloged and debugged; IntelliFAB makes editing and organizing large process tables easy. Built in grouping, filtering, and arrangement tools allow you to section, organize and debug large process tables. IntelliFAB allows you to quickly build and debug your process traveler down to the last detail. Foundry ready templates Processes can be custom-designed one step at a time, or engineers can draw from a wide range of foundry-ready process templates. Users create their own process flows from a database of over 70 process steps or by including custom process steps. Process flows can be saved as templates for repeated use.
