3D TCAD Analysis Enabling ESD Layout Design Optimization

Layout Data in Tcad Frameworks

Today Technology CAD (TCAD) tools are essential to the development of modern Integrated Circuit (IC) fabrication processes. They are as well, required in the design/ optimization of very detailed and critical circuits related to a given IC process, where the usual higher level tools in Electronic Design CAD (ECAD) frameworks do not exhibit the precision or the features required. The boundary be...

Layout Design Rule Generation with TCAD Tools for Manufacturing

Thls paper presents a methodology for estimating the effects of changes in the layout design rules on the manufacturability of a VLSl technology. 2-D process and device simulations were used to estimate parametric yield, while functional yield was predicted with state-of-theart y~eld modeling tools. A spectrum of TCAD tools was therefore capable of estimating the resulting number of good chips ...

Automatic Device Design Optimization with TCAD Frameworks

A design optimization method is presented which utilizes automatic optimization capabilities within TCAD frameworks. This method is applied to doping profile optimizations of ultra-low-power CMOS transistors with 0.25 and 0.1 μm gate lengths. Two different performance goals are utilized, to maximize the drive current of an NMOS transistor and to minimize the gate delay time of a CMOS inverter s...

Architectural Layout Design Optimization

This article presents an optimization model of the quantifiable aspects of architectural floorplan layout design, and a companion article presents a method for integrating mathematical optimization and subjective decision making during conceptual design. The model presented here offers a new approach to floorplan layout optimization that takes advantage of the efficiency of gradient-based algor...
