TCAD, as Individual as Your Demands

TCAD Introduction

Technology CAD

In the field of Electronic Design Automation (EDA), Technology Computer Aided Design (TCAD) simulation software is used for development and optimization of semiconductor device structures. In order to provide accurate simulation results for a wide range of device technologies based on various material systems, a physics-based approach is employed. Depending on the device's dimensions and dominant physical effects, either classical or quantum mechanics based simulation tools are applied. While the former rely on a hierarchical set of partial differential equations (PDEs) describing carrier flux and conservation, the latter are based on the solution of the Schrödinger-Poisson system and are typically used for emerging nano-scaled technologies.

Usage: Design for Manufacturability,...

Design for Manufacturability (DFM) is probably one of the main reasons for using simulation tools, but the fields of application are wide: Due to their predictive character, TCAD tools are present all over a device technology's lifetime. They are used to explore novel structures for the rapid and cost effective development of upcoming devices, even without expensive and time consuming wafer runs. Later on, Design of Experiment (DoE) and optimization strategies are deployed in order to characterize and optimize the fabrication processes. Finally, mass production is facilitated by improvements of the parametric yield.

General Applications & Benefits

GTS Framework provides you with a suite of invaluable helpers all along a semiconductor technology's lifetime. Find out about the benefits you get from using GTS Tools in typical areas of application:

Virtual prototyping of novel device concepts

GTS Framework comprises a versatile tool set for early development of novel device concepts as well as performance analysis. Device structures can be characterized before the first prototype has left the line or even before fabrication processes are defined. Therefore, time to market is shortened drastically at a fraction of the cost generated by extensive experimental work.

Optimization of existing device designs

When settling a newly defined fabrication line, GTS Framework provides your tools to analyze sensitivity of device characteristics on process variations. Dedicated modules for optimization and Design of Experiments allow full investigation of the existing parameter space while minimizing development time and experimental runs. Thus, yield can be enhanced with minimum effort – and at a fraction of the cost of experimental procedures. 

Gaining profound physical knowledge

Due to the fundamental underlying equations, the simulators can be used to gather deep physical understanding of a device's behavior. In addition to experimental data describing the outer behavior of a device, the GTS simulators provide comprehensive insight to the inner effects defining the device's characteristics. Thus, GTS tools cut development time and cost drastically.

Intuitive graphical interface

The outstanding graphical user interface allows for quick adoption and highly efficient use. Compared to legacy tools, GTS Framework boosts productivity, and therefore is ideally suited to the daily demands in industrial environments.

Predictive modeling

Carefully calibrated models based on a wide range of experimental data and full-band Monte Carlo simulations ensure the best possible accuracy and thus enable predictive simulation of arbitrary device structures. Especially for predictive simulation of upcoming devices and new channel materials (such as III/V materials), GTS Framework includes unique physical models, providing unprecedented insight in quantum-mechnical phenomena — key for making the right decisions in device design and optimization.

Development and calibration of compact models

For subsequent use in circuit simulators such as SPICE, GTS Tools can be used to identify and calibrate lumped models of different complexity.

Interoperability

Input/Output modules for the most industry standard simulation and visualization file formats allow the seamless integration of the GTS Tools to existing workflows.
