Using Athena Monte Carlo Module for Ion Implantation Simulation in Silicon Carbides

Introduction

The Monte Carlo Implantation Module of ATHENA has proved to be a very accurate tool for simulation of various implantation processes. In this paper we demonstrate that the module can be successfully used not only for classical silicon-based technologies but also for other materials used in semiconductor industry. Silicon carbides were selected for this demonstration not only because they are widely used in power and high frequency electronics but also because they are most challenging objects for simulation due to their complicated lattice structures and electronic stopping models.

Expert’s Netlist Driven Layout

Expert features a powerful Netlist Driven Layout (NDL) function to assist the user in creating a layout. It increases the productivity of layout design by automating cell generation and providing visual cues to assist in the wiring process. In this example, a latch circuit layout will be built based on developed child cells.

Expert Parametric Wires

Expert Parametric Wire (Pwire) is a complex group of objects containing, a single wire named master wire, any number of subparts such as enclosure wires, offset wires and sets of rectangles. Pwire objects enable extremely quick and efficient creation and editing of guard rings and shielded paths which are increasingly important due to higher integration density of IC designs.

Simulating the Device Characteristics of MEH-PPV Polymer Light Emitting Diodes Using Atlas

Organic light emitting diodes (OLEDs) are attracting great interest in the display technology industry due to their promising low cost large area manufacturing and relative ease of fabrication using low processing temperatures. Although the research work of OLEDs has began since early 1980 and has been well established, there is still no commercially available software that can simulate the electrical and optical behavior of these organic polymer/monomer based devices. As such, Silvaco-ATLAS has recently extended its capability to simulate these devices using a variety of appropriate organic polymer/monomer models.

Expert: Wiring

The wiring tool in Expert automatically creates the shortest wire connecting two points specified by the user. The created wire goes around any existing layout objects. It may lie in multiple layers (multi-wire) if the source and target points are on different layers or if the wire is shorter than the alternative single-layer wire case.
