What is standard FDD
mounted insemiconductor manufacturing equipment?
FDD mounted on typical semiconductor manufacturingsystem (especially sputtering and CVD) is SCSI type which
differs from general ATAPI FDD available in the market

Current issues of SCSI type FDD
１．Already discontinued⇒

FD Drive

Unavailable in the market（SCSI type）

3.5” Floppy（Medium）

Discontinued

Discontinued

２．Slower Access speed⇒

It takes a lot of time for data backup.

※The more data files like recipe and sequence exist, the longer back-up time is needed.
(It is quote common that back-up takes more than one hour)

３．Breakable⇒ Failure of unit recognition occurs frequently.

Unit is easy to break when user merely boots equipment. However, alternative unit is
no longer possible to procure.

Proposal of SCSI type CF(Compact Flash) unit for major
semiconductor manufacturing systems
Full compatible CF unit to SCSI type FDD
１．Easy installation
Installation is quite easily!
※Modification of equipment or change of program is unnecessary.

２．Operation is exactly same as FDD.
※Process of writing and reading of data is operated under thesame command as FDD.

３．Fast access speed

SCSI type FDD full compatible
CF（Compact Flash）unit

Model：ACD-73100※Compared with FDD, access speed is remarkably fast.
Back-up time of data is largely reduced ⇒ work efficiency improved※Ref. Back-up time reduction ： FDD／approximately 60min ⇒ CF／app. 3min

The reason why we say it is completely compatible :※The unit name in the system is defined as “TEAC TC-1” which is a model name of standard FDD.
When the system is booted, BIOS recognized the unit under the name of “FC-1”.

Pics of installed unit
We have already installed a lot of CF units in major semiconductor
manufacturing equipment in Japan. These customers are all satisfied withthe performance of the unit in data access speed and easiness of operation.

Ref. Installed in CVD equipment※User can install CF by using 148mm
special installation fixture (option).

Ref. Installed in PVD equipment※Installed by standard fixture attachedwith CF unit.

４．Format of CF Medium１． Detachment of OEM FDD

At first, detach both SCSI (50 pins flat cable) and power supply cables which
are connected to OEM FDD under a condition of “machine power-off”.

In this case, please check where in SCSI cable the OEM FDD is connected to.
※Check whether it is connected to tip of connector of cable or connector located in the center ofcable. D/S setup shown in next page is implemented in accordance to the connection points.

２．D/S setup of CF unit
Operator setup D/S (DIP Switch) located at the bottom of CF unit.
１．Set-up of SCSI ID(Setup SW1, SW2, SW3）

Generally, in case of major semiconductor manufacturing equipment, operator
sets SCSI ID as ”１”

２．Setup terminator（Setup of SW5, SW6)

Operator sets-up D/S by checking as SCSI cable is surely fitted to correct position.
In case, CF is connected to connector of tipof cable.

Connect both SCSI cable and 4 pin power supply cable to CF unit at first andmount the CF onto equipment.
※Please use attached conversion cable (power supply cable of 4 pin small⇒4 pin large)

In case of VME rack such as CVD equipment C and PVD machine E, please
mount attached 128mm panel onto CF unit. For CVD tool P, accurate installation
can be done by using 148mm panel (sold in option. See left picture).

Ref. Installed at major
CVD equipment P

After CF unit is mounted , power-ON the system and check if the equipment
surely recognizes the CF unit. If monitor of the system displays unit name as“FC-1”, the recognition is done successfully.

４．Format of CF Medium
CF unit (ACD-73100) includes 6 pieces of CF medium. For equipment makerA, the CF unit is only recognized up to 1.44MB as same as FDD so user has
to format attached CF medium by “format U2:” command at first.
※Format of CF medium is completed within a few second (approximately 3seconds).
After the format completes, use the CF unit like as legacy FDD.

Why don’t you try
an unit for evaluation?

・Installation and setup is very easy!
・Easily applicable to multiple equipment!
Therefore,
It is possible to back-up data by installing this product whenevernecessary.
*）The CF unit is compatible to limited semiconductor equipment (PVD, CVD) only.

Dramatically reduce back-up process and time before cessation ofequipment.
