Applications of the Structural Comparison Algorithm for Simulated Annealing Optimizations and Stochastic Simulations

Curotto E., Beaver College, US

The use of a structural comparison algorithm as a potential energy surface attractor map is introduced. The numerical procedure determines if two structures of a Xn and Xn-YZ species are identical from the respective Cartesian [...]

RESCUER – the New and Effective Tool for Automatic Models Reduction – Application for Electro-Thermal Problems

Napieralski A., Zubert M., Napieralska M., Technical University of Lódz Al, PL

This paper presents some methods of thermal model reduction and translation into hardware description languages or other ones. The very effective model reduction is achieved owing to the application of higher order approximation and joint [...]

A 2D Visualization Tool for SUMMiT V Designs

Yarberry V.R., Jorgensen C.R., Sandia National Laboratories, US

This paper describes the 2D Process Visualizer, a CAD tool that enables a SUMMiT (Sandia Ultra-Planar Multilevel MEMS Technology) MEMS designer to visualize the results of applying the process sequence to a mask set by [...]

Modeling of Electromagnetic Fields in High Speed Electronic Interconnects Using a Least Squares FD-TD Algorithm

Tramel R.W., Turowski M., Przekwas A.J., Schultz J., Frey R.G., CFD Research Corporation, US

A new Finite-Surface Time-Domain (FS-TD) numerical method is presented which is a generalization of the classical Finite-Difference Time-Domain (FD-TD) method of Yee. The method is divergence/charge preserving on arbitrary grids. It reverts to the standard [...]

Fail Pattern Classification and Analysis System of Memory Fail Bit Maps

Nakamae K., Itoh A., Fujioka H., Osaka University, JP

In order to determine problematic wafer processing steps rapidly during memory production, the system that classifies failure patterns from memory fail bit maps (FBMs) and estimates the cause of failure is proposed. The system mainly [...]

A 3D Geometry Modeler for the SUMMiT V MEMS Designer

Jorgensen C.R., Yarberry V.R., Sandia National Laboratories, US

This paper will describe the SUMMiT V 3D Modeler; a 3D geometric modeler based on Sandia National Laboratories new five-level process for manufacturing microelectromechanical systems (MEMS). The modeler simulates the SUMMiT V process, a baseline [...]

Convergence and Speed Issues in Analog HDL Model Formulation for MEMS

Iyer S., Jing Q., Fedder G.K., Mukherjee T., ECE Department, Carnegie Mellon University, US

Behavioral simulation using high-level hardware description languages (HDLs) is becoming increasingly relevant for mixed-domain MEMS simulation. In this paper three issues which impact the convergence and simulation time in MEMS behavioral simulations are addressed. First, [...]

A Data Model for the Representation of Fabrication Dependencies Concerning Micromechanical Devices

Hansen U., Büttgenbach S., Technical University of Braunschweig, DE

Conventionally the design of a product is conducted paying only little attention to the subsequent manufacturing. Regarding micromechanical devices this is not practicable, since the design choices taken are highly dependent on the technology used [...]

Coupled System-Level and Physical-Level Simulation

Furmanczyk M., Turowski M., Yu E., Przekwas A.J., CFD Research Corporation, US

Software tools for Mixed-Level Coupled Simulations have been developed. The system-level simulation uses the circuit theory approach, where each element of the system is modeled either through mathematical equation, or through coupling with physical-level 3D [...]

System Model for a Novel No Moving Parts Diffuser Valve Based Diaphragm Actuated Micro Pump

Banerjee D., Yano K., Bart S.F., Coventor, US

Analytical results for oscillating flow in a channel indicate regions of high shear stress close to the wall along with the flow reversal in the central portion of the flow at certain frequencies of actuation. [...]
