Characterization of active devices

Unlike traditional TCAD tools, DevEM's understanding of the entire layer stack enables designers to characterize an actual device from layout. Simply create the device as normal in your layout tool, import the GDSII into the Magwel 3D editor EditEM and then DevEM will perform DC and high frequency analysis up to 100 GHz or more showing the true performance of your transistor. Begin creating your compact models sooner and with less reliance on lab measurements.

Device Simulation

Since the MAGWEL solver is able to deal with both metal and semiconductor materials, it is possible to use the solver for device simulation purposes. What is even more interesting: the MAGWEL solver is developed in a fully three-dimensional set-up. Therefore, it is possible to obtain results for device structures that are truly three-dimensional. Analysis of the device architectures can be done, starting in the static regime as well as in the frequency regime.

Examples of applications include:
  • RF CMOS transistors
  • Diodes
  • Varactors

Of particular interest is the analysis of the semiconductor part of the devices together with the lowest metallic layout. The current redistributions that take place at the metal/semiconductor interfaces can be accurately computed.

For multi-finger gate layouts, it is possible to evaluate the 'inter-finger' skin effect that will influence the transistor operation at high-frequency.

RF CMOS transistors can be analyzed by integrated simulation of the metal and the silicon parts of the full device.
