Introduction
1. Safety precautions
1
Most accidents are attributed to carelessness during operation, inspection, maintenance, or repair.
Failure to comply with the safety precautions or neglecting to anticipate danger causes accidents
to happen more easily. Accidents can be prevented before they happen by anticipating potentially
dangerous situations at an early stage.
2
Accidents involving injuries are caused by erroneous operation or inadequate maintenance and
inspection work.
Never try to operate the system before carefully reading and understanding the operation,
inspection, and maintenance sections.
3
Warnings and precautions about safety are listed in this manual and on the system's warning labels.
Ignoring these warnings and precautions may lead to injury or loss of life, so use caution.
4
Supervisors, operators, and maintenance personnel should read this manual before operation or
maintenance. Only those who know how to handle the system and have received training should
perform the appropriate work on the system using the correct techniques and tools.

Introduction
2. Safety symbols
Safety symbols are used throughout this manual and labeled on the system to call the operator's attention
to safety.
The terminology used in safety symbols is classified below.
This symbol indicates the possibility of impending death or serious injury
when the hazard cannot be avoided.
Work that ignores this warning has a high probability of severely injuring people or
damaging factory equipment (including this system).
This symbol indicates the possibility of death or serious personal injury when
the hazard cannot be avoided.
Work that ignores this warning will severely injure or damage factory equipment
(including this system).
This symbol indicates the possibility of minor injury or moderate damage to
the system when the hazard cannot be avoided.
Work that ignores this warning carries the risk of minor injury to the operator,
damage to the system, or necessary adjustment of the system.
There is no direct danger, but this symbol notes content you should know to work
safely and to use the system correctly.
It is not possible to precisely anticipate all potential dangers in operation, inspection, or maintenance in
all operating environments.
The warnings listed in this manual and on the warning labels affixed to the system do not satisfy every
aspect of safety.
When handling the system, those who administer, operate, or maintain the system should pay the utmost
care, even for items not mentioned in this manual, and work to maintain safety so that serious accidents
like injuries or damage to the system do not occur.
When operating, inspecting, or maintaining the system in a manner not described in this manual, all
workers must perform that work at their own responsibility paying careful attention to the necessary
safety precautions.

1. For Safe Operation
In order to safely use the system, this chapter describes the precautions, locations of warning labels, and
contact information for safe operation.
1-1. Precautions when handling the system
This section describes safety precautions for the system. Carefully read and fully understand the items
below before using the system.
Danger
The voltage generated by this power supply is sufficient enough to pose a danger to human life.
The utmost care must be taken when handling the system. If by some chance a person touches
this high voltage current, it will lead to a serious accident. Take great care not to come into
contact with high voltage current. Danger: Never energize the power supply with the cover
removed.
Danger
This power supply internally handles high voltages. When inspecting inside the power supply,
always shut off the primary-side switch of the power supply used and then wait for three
minutes or more before opening the cover.
Maintenance work must be done by a technician with experience handling high voltages or
under the direction of such a person.

1-2. Warning label/nameplate locations
Reference
The locations where warning labels are affixed to the system are shown in the reference
materials in Chapter 8. Make sure these warning labels are always clean and legible. Use a cloth
and water to clean the warning labels. Do not use gasoline or organic solvents. If a label is
damaged, missing, or illegible, contact ULVAC or an exclusive dealer. A nameplate is also affixed to
the top surface of the power supply. Take special care to ensure the nameplate is always legible.
1-3. Contact information
To order parts, ask questions about the system, and to make inquires related to system malfunctions,
first verify the system information and then contact ULVAC. Especially when you have determined the
system has malfunctioned, inform us of the system information along with the system's history and
symptoms in as much detail as possible.

2. Overview
This chapter describes the system's features, configuration, and specifications.
2-1. Introduction
This system has been designed for plasma generation in RF sputtering, plasma CVD, etching, and other
plasma processing applications. This system combines an RF power supply and matching box. It can
continuously output its rated power at a single frequency of 13.56/27.12 MHz for high frequency loads. This
system also has a control terminal that makes external control by a PLC possible.
2-2. Features
The solid-state design eliminates consumables with short life-spans like vacuum tubes and has
increased reliability.
A stabilized oscillation frequency can be obtained by quartz crystal oscillation.
Reduced size and weight have improved maintainability significantly.
Accurate power can be read by the linearized power meter.
Built-in power factor modification circuit improved efficiency significantly.
The matching box allows you to freely select manual or auto mode.
