Mid summer release of SEMulator3D adds more accuracy for deposition & CMP

By David M. Fried

Today we officially released SEMulator3D 2014.100. Typically, I wouldn’t be so excited about a “point release”, but this is clearly the biggest interim software release in recent SEMulator3D memory. We’ve added significant capability to an already industry-leading virtual fabrication platform. Many of the features of recent SEMulator3D releases have been focused on Etch enhancements. To complement these enhancements, we’ve stepped up the predictive accuracy of several other process models in SEMulator3D 2014.100, including Deposition and CMP.

The highlight of this release is a new Visibility-Limited Deposition model. This model dramatically improves the predictive accuracy for directional depositions, like Physical Vapor Deposition (PVD) and other plasma enhanced deposition processes. As with other process models in SEMulator3D, we’ve made this process simple to implement and calibrate using a reduced set of process parameters. The key features of this Visibility-Limited Deposition model are the “Source Sigma”, reflecting the directional distribution of the process, and the “Isotropic Ratio”, reflecting the non-visibility-limited component of the deposition process. This model enables a large variety of processes, with a wide range of results.

Coventor Brings More Accuracy & Performance into Design of MEMS Devices

by Pawan Fangaria
SemiWiki

Although MEMS devices in various forms are now found in most electronic devices, predominantly in mobile, automotive, aerospace and many other applications, their major revolution, I believe, is yet to happen. We are seeing rapid innovation in MEMS reflected by their improvements in precision, performance, size reduction, and the continuing evolution of new devices with increasing complexities. The micro level fabrication of MEMS will enable unprecedented use of these into newer and newer semiconductor based electronic devices that will revolutionize the so called IoT arena. MEMS will be essential to IoT products’ ability to connect every aspect of our life, things and happenings around us and provide us ultimate knowledge, control, security through a wide range of devices in many form factors and environments.

Linking Virtual Wafer Fabrication Modeling with Device-level TCAD Simulation

By Mike Hargrove

Most process/device simulation tools are TCAD-based. By this, I mean they share a common platform which connects the process simulator to the device simulator, usually using the same mesh structure. Most all of these TCAD tools are finite-element based, and the 3D final mesh structure is tetrahedral in nature. The mesh structure contains many nodes which define solution points for the numerous complex set of equations required to create the physical structure, in most cases a transistor, and solve for the electrical characteristics of the device. One of the drawbacks of TCAD is the computational time required to arrive at a solution – both process model solution and device electrical solution. A larger modeled area (e.g. multiple transistors and/or an SRAM cell) usually means longer simulation time.

Coventor’s virtual wafer fabrication approach addresses this challenge. Our process modeling platform combines with the statistical device TCAD suite of tools from Gold Standard Simulations, LTD. (GSS) to produce SRAM device-level simulation capability capturing real process-induced statistical variation. The ultimate objective of statistical device modeling is to capture the intrinsic variation of physically relevant process parameters. The combination of Coventor SEMulator3D process modeling capability and GSS statistical TCAD simulator GARAND fulfills this objective.

What will the next 30 years of MEMS bring?

Steve Breit, VP Engineering
June, 2014

Coventor attended the Solid State Sensors, Actuators and Microsystems Conference last week, known simply as “Hilton Head” to the North American MEMS and nanotechnology community. This is a delightful conference held every two years at the same beachfront resort on Hilton Head Island, South Carolina. The location and single track of oral presentations create a congenial atmosphere for engaging with other participants.

At the opening, the conference chair Professor Mehran Mehregany of Case Western Reserve noted that this was the 30th anniversary of the conference and remarked on the incredible technical progress over that period. In 1984, the year of the first conference, MEMS products were only a gleam in the eyes of a select group of researchers. Today, MEMS ship in the billions and are ubiquitous in automobiles, mobile devices, and many other products. Professor Mehregany then asked the assembled micro- and nanotechnology research community a provocative question: Now that MEMS have become a reality, what should we do for the next 30 years? To help the research community answer this question, the organizers assembled a panel of four science fiction writers who shared their speculations on what might be possible in 30 years.
