What Is Plasma CVD? In thin-film formation, it is important to deposit materials uniformly on a substrate. Plasma CVD is a method of forming thin films by activating source gases with plasma and causing chemical reactions on the substrate surface. Compared with conventional CVD, which relies mainly on heat to drive reactions, plasma CVD can promote reactions even at relatively low temperatures. For this reason, it is widely used for forming semiconductor films, insulating films, and protective coatings. In this article, we will use PIC-PLASMA 3D (plasma analysis software) to analyze plasma distribution inside an industrial plasma CVD reactor and ...

In this article, we will analyze electron trajectories inside an SEM (Scanning Electron Microscope) using PIC-PLASMA 3D (plasma analysis software) or PIC-ELECTRON 3D (electron trajectory analysis software). SEM (Scanning Electron Microscope) is a device that scans the sample surface with a finely focused electron beam to observe microscopic shapes and structures. Even regions that are difficult to observe with an optical microscope can be examined at high resolution by using an electron beam. Electron Trajectories Inside an SEM Figure 1: Conceptual illustration of electron trajectories in an SEM What is an SEM? In an SEM, electrons emitted from the electron ...

This time, we will analyze the electric field of semiconductor devices using ELECTRIC-FIELD 3D (electric field analysis). About electric field analysis in semiconductors Figure 2: Conceptual diagram of a silicon capacitor Inside semiconductors, electrons and holes are accelerated and moved by electric fields. In other words, without understanding the electric field distribution, it is not possible to accurately grasp how current flows, how charge accumulates, where dielectric breakdown is likely to occur, or what the switching characteristics will be. The main reasons are as follows. 1. To determine the movement of electrons and holesCarriers in semiconductors move under electric fields, ...

In this article, we will simulate electron trajectory analysis inside an electron gun using PIC-PLASMA 3D (plasma analysis software) or PIC-ELECTRON 3D(electronic trajectory) analysis software. An electron gun is a device that generates, accelerates, and narrows electrons into a beam. It is used to create electron beams in a vacuum and is utilized in electron microscopes, CRTs, X-ray tubes, and some particle accelerators. Electrons Inside an Electron Gun Figure 1: Conceptual diagram of electron trajectories in an electron gun Electron Emission In a typical electron gun, electrons are emitted from the cathode. There are three main methods of electron emission: ...

  What Is Plasma? Figure 1: The Four States of Matter Matter is commonly classified into solids, liquids, and gases, but by heating a gas further, it is possible to generate plasma. For this reason, plasma is often described as the “fourth state” of matter.   This time, we will analyze plasma discharge using PIC-PLASMA 3D (plasma analysis software). As explained earlier, plasma refers to a state in which an electrically neutral gas becomes ionized and contains many free electrons and ions. In other words, plasma can be regarded as “a high-energy gas state that has become highly conductive.”   ...

What is plasma Matter is commonly classified into solids, liquids, and gases, but heating a gas further can produce plasma. Therefore, plasma is described as the ‘fourth state’ of matter.   This time, we will analyze fluorescent lamps, an industrial product that utilizes plasma.   Fluorescent lamps consist of a glass tube, a small amount of mercury, an inert gas such as argon, electrodes at both ends, and phosphor coating the inner surface of the tube.The phosphor absorbs ultraviolet light generated by the discharge and emits visible light. Fluorescent lamps are utilized not only in ‘residential and living spaces’ but ...
