In order to perform 3D analysis, however, designers need to accurately specify the structure to be simulated. A virtual integrated process modeling tool, based on a set of techniques which enable the construction of 3D device structures, is presented with emphasis on a new technique to build 3D LOCOS geometries. Examples illustrate how this technique is used to construct both a test structure as well as an actual memory cell design.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.

For this reason, within the project PROMPT a multidimensional process simulation software capable to provide appropriate input to three-dimensional device simulation has been developed by a European consortium. The PROMPT software compiles the geometry and the dopant profiles of the device from the results of existing one- and two-dimensional process simulators and three-dimensional modules newly developed. Within this presentation, the capabilities of the three-dimensional ion implantation module developed at FhG-IIS-B within PROMPT are being outlined.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.

To improve product reliability, it is very important to control mechanical stress in device structures. This is because the stress field changes the dopant distribution and shifts electronic characteristic of devices due to piezoelectric effect. There are several stress development processes in the device manufacturing, such as thermal stress due to mismatch in thermal expansion coefficients among thin film materials used in the device structure and intrinsic stress which occurs during film deposition. To evaluate precise stress fields in actual device structures, the authors have developed stress simulation methods based on finite element analysis, a measurement method for mechanical properties of thin films, and a microscopic stress measurement method. To improve product reliability of silicon devices, it is confirmed that these methods are effective for control or optimization of mechanical stress fields in the device structure. In this paper, the stress evaluation methods are applied to discuss the effect of passivation film stress on the shift in threshold voltage of GaAs FETs.","PeriodicalId":341161,"journal":{"name":"1996 International Conference on Simulation of Semiconductor Processes and Devices.

Where in two dimensions many different and only moderately sophisticated methods are established and feasible, there is the need in three dimensions for far more efficient strategies. Not only the amount of data and the complexity of the simulated structures pose an increasing challenge, but also the visualization of the three-dimensional grid as an important feedback for the developer becomes more difficult. Meshing has been geared more and more towards automation. Especially, in Technology Computer-Aided Design (TCAD) where the input to the gridder can be the output from a topography simulator the degree of automation requires further discussion.
