    1. General Information

1.1 Introduction

    Chemical Vapor Deposition or CVD is a broad class of processes using controlled chemical reactions to create layers on substrates. CVD involves the formation of a solid film on a heated substrate surface by means of a chemical reaction in a gas or in the vapor phase. This process employs various gaseous, liquid and solid chemicals as sources of the elements of which the thin film is to be made. In comparison with most thin film preparation methods, CVD has a number of unique advantages such as the versatility用途广泛, adaptability适应性, compatibility兼容性, quality, simplicity, re-

    productivity, productivity, and cheapness. For these reasons, CVD has expanded continuously and developed into the most important method for producing films for solid-state devices. CVDs are classified by AP (Atmosphere Pressure) CVD, LP (low pressure)

    CVD, PE(plasma enhanced) CVD, MO (Metal Organic有机金属) CVD.

    MPECVD-RA which using PECVD technique takes advantage of the high energy electrons present in glow discharges to dissociate and ionize gaseous molecules, thus generating chemically active radicals and ions. Hence, PECVD can be performed under relatively low temperature. To make or maintain a chemical reaction and using Microwave or RF-enhanced glow discharge, PECVD forms a film by conveying energy to reacting gas. Compared with the APCVD or LPCVD production process, this process lets you operate at low temperatures and also has the advantage that the depositional speed is fast.

    1.2 Safety Information

1.2.1 Overview


    ? Please read this manual and safety information in all related manuals before

    installing or using the instrument.

    ? The safety notes and regulations given in this and related documentation have to

    be observed at all time.

    ? Check for correct main voltage before connecting any equipment.

     Warning: Lethal Voltages!

    ? Adjustments and fault finding operation may only be carried out by authorized

    personnel qualified to handle lethal voltages.

    ? Lethal voltage may be present at parts of microwave generator/component itself

    during operation.


    ? All the connectors which were originally supplied with fixing screws must always be used with their fixing screws attached and tightly secured.

    ? Leave it for a few minute after switching off for any stored energy to discharge.

    MPECVD-Manual -7-


    ? Cooling water: The water pressure switch is interlocked to avoid break-down of the

    vacuum chamber and Magnetron. If the water pressure is low or stop, buzzer is

    operated, and then the microwave generator power is down.

    ? Ultimate vacuum pressure: The microwave generator was not operated when the

    pressure is lower than setting ultimate pressure

    ? Vent valve: The vent valve is not opened when the V6(main gas inlet valve) valve is


1.2.2 Microwave Radiation

    No ionizing radiation is electromagnetic radiation that does not disrupt the

    chemical bonds in biological molecules. The electromagnetic frequencies

    that produce photon energy of less than 0.1 electron volts, and hence are

    called no ionizing, are those frequencies below roughly 2.45Ghz. For

    reference this is just above the ultraviolet frequencies.

1.2.3 High Voltage

    - Danger: High Voltage 5kV in inside the microwave Generator, Power Head

    and the HV cable

    - Danger: High Voltage 2.0kV in DC power supply.
