We are pleased to announce the release of CoventorMP 2.1, which includes MEMS+ 7.1 and CoventorWare 11.1. New features streamline device creation and make simulation results easier to load and view.
These new features help you easily create more accurate models:
Create multi-physics models effortlessly: MEMS+ now automatically connects a planar movable gap to a meshed plate, thereby easily adding electrostatic, contact, and squeezed-film damping models for simulation. This feature offers improved sensor and actuator modeling for all designs.
Automatic hierarchy generation of components upon construction: Add-on components now have an “Automatically Add to 3D Schematic” capability, which streamlines model creation when using either the Construct 3D Model option or during manual model construction. This feature automatically adds child components such as gaps, stacks, stators, and rigid plate segments, when their parent is created in Innovator.

Instantaneous Symmetrical Mesh Creation: Copied, replicated, or moved meshed components will have the same mesh as the original. These actions will not trigger a remesh of the entire device. This feature will save meshing time and ensure construction of symmetric meshes that will capture orthogonal and spurious modes with increased precision.

These new features help you simulate more efficiently:
Automatically Reload Result Data: The MEMS+ Simulator msim file now loads simulation results and MROM models that were saved with the file. GetInfo information and 3-D results are loaded and ready for viewing without rerun an analysis. An MROM model saved with the msim does not have to be regenerated before running any nested simulations.
More efficient noise analysis: The linear solver used in Simulator noise analysis has been updated to a version with faster simulation time; users may see a slight change in results.

Process engineers have to make a trade-off between silicon loss and residual SiGe.(b) Variation in residual SiGe as a function of the channel width and etch lateral ratio. The higher the channel width, the higher the lateral ratio needed to etch away all the SiGe. Channel widths are shown as delta values from the nominal value of 30 nm.
