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.

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.

Introduction

The functionality Silvaco’s Layou Editor, Expert, has recently been expanded with the new feature called Layout Versus Layout comparison (LVL).

LVL is available as a separate window called by menu commands:

The increasing demand of the TFT-LCD industry has lead to a rapid growth in display size and resolution. The higher cell packing density results in a narrowing viewing angle and image degradation due to electrical coupling between the data bus lines and display electrodes. This “crosstalk” therefore becomes a serious limitation. The in-plane switching(IPS) mode has been used as an excellent technology solution for realizing extremely wide viewing angles.

In certain cases, most notably in modern bipolar and SiGe HBT structures, epitaxial steps are performed after the oxide isolation structures have been already created. Thus the initial surface prior to epitaxy may contain regions of crystalline silicon, polysilicon or insulators, usually silicon dioxide. In the case of LOCOS isolation, the surface is also non-planar.
