AdvantageS of CVD
Classification of CVD
Thermal(conventional) CVD
- Operating Temp. : 800 1200 ℃
- Mass Products
- High Purity Thin Film
- influenced by various factors
Metal-Organic CVD(MOCVD)
- Metal-Organic compound
- High reproducibility
- Low-Temperature
- Complex structure
Plasma Enhanced CVD(PECVD)
- Using a Plasma
- Low-Temperature
- High deposition rate
- Li
○ PECVD
∙ What is PECVD?
⇒ Radio frequency(RF) is used to induce plasma in the deposition gas.
⇒ This results in a higher deposition rate at relatively low temperatures.
⇒ With the plasma enhanced CVD process is the deposition at temperature around 300℃ allows.
⇒ The temperature will be through encouragement of a plasma with high frequency electric fields triggered.

I. Introduction
1. Purpose of the Project
The purpose of this our group was to analyze two similar hospitality companies by using tools learned in accounting class. Based on annual reports of two companies, our group members learned how the terms learned in class is actually used in the report. We hope to understand how certain variation affects accounting items and identify why certain does
