Q. When I simulate my process flow the simulated profile is always lower than the SRP measurements. What could be causing this? A. In many simulated process flows the surface oxide is etched completely off after which there may be some diffusion cycles.
The rapid evolution of modern photonic devices in digital photographic and detection systems creates a need for physically-based simulation of charge collection and transfer. In this article we show the linearity, spatial sensitivity, and spectral response of a generalized silicon pixel structure using the Luminous module of the ATLAS device simulator.
This article will present an efficient and original methodology for global and predictive modeling of low energy Boron, BF2 and Arsenic ion implantation, in the suitable range for sub-100nm CMOS technology.
A primary use of QUEST is intended to be for extracting frequency dependent transmission line models for use in SPICE circuit simulations. The generation of SPICE parameters for transmission line models is becoming increasingly important as clock speeds approach and exceed the 1 GHz frequency range.
Q. How can I extract VBIC bipolar model parameters using UTMOST III? A. UTMOST III Bipolar module can be utilized to extract and optimize the VBIC model parameters for bipolar devices.
With the advent of ever increasing operation frequencies, Silvaco is introducing a new high frequency model for MOSFETs that will be implemented into the SmartSpice code. This article describing these new models will be in two parts.
Until now, SmartSpice has supported the TriQuint model designated TOM using the Level=5 model parameter. SmartSpice now supports the TriQuint-2 MESFET model designated TOM-2. This model is accessible as a standard MESFET model, using the Level=7 model parameter. It is an incremental improvement based on TriQuint?s original MESFET model. All current analyses are currently supported (dc, ac, transient and noise).
The University of Florida SOI Group first released version 5.0 of UFSOI model in August 1999 and then in November 1999. To keep backward compatibility with previous versions, two model parameters (VERSION, REVISION) have been added in SmartSpice to select the desired model. By default, the value of VERSION is 5.0 and the value of REVISION is 1.0 which corresponds to the last release of November, 1999.
Q: Usually, when I want to change the display of a drawing in the Drawing window, I select the Window pull-down menu in order to zoom in/out, pan, and fit. Sometimes, if I need to do these operations, this way is not convenient. What is a more effective way to control displaying?
One of the most useful features of the Scholar schematic capture is tight integration with the SmartSpice simulator. In effect, Scholar makes it possible to automatically generate SmartSpice netlist on the basis of the schematic. Such a possibility covers both analog and digital designs.
