Hub of i2000 implanter holds thirteen
300-millimeter wafers in each batch.
In a move that enables
the semiconductor industry to remain on track with Moore's
law regarding the production of new, more advanced IC
devices, Ibis Technology Corporation developed
its new i2000 oxygen ion implanter.

The i2000 implanter end-station load ports can accommodate
300-millimeter wafers in FOUP or
open cassettes.
Building on the success of Ibis model 1000 implanters,
this third-generation
implanter is a high-throughput, high-volume production
tool for manufacturing 300-millimeter SIMOX-SOI
wafers.
i2000 Implanter Flexibility
- Ibis' i2000 implanter can accept 300-mm
wafers made of silicon, or a combination of silicon
and silicon germanium, or other combinations of materials.
By using a range of manufacturing processes, the system
can produce a variety of SIMOX-SOI wafers, including
Advantox MLD and MLD-UT wafers, patterned SIMOX-SOI
wafers and strained-silicon-on-SIMOX-SOI wafers. All
of these are dependent on the starting wafer. We believe
the system' s flexibility is well suited to the era
of Silicon Plus.

Modular design - The
i2000 implanter is divided into five modules, designed
to simplify the process of shipping and reassembling
the system at the customer's facility.

|
Front
End |
The Front End Module is where starting wafers
are loaded and implanted wafers are unloaded.
The factory interface is available with a wide
variety of industry-standard load ports. The i2000
implanter end-station load ports can accommodate
300-millimeter wafers in FOUP or open cassettes. |
|
Process Chamber |
The Process Chamber Module contains the rotating
hub which scans the wafers through the ion beam.
This module also contains the lamp modules, which
are used for heating the wafers before and during
implantation. |
|
Beam Line |
 |
| Ibis i2000 beamline |
The Beam Line Module contains the
patented Ibis MagScan
which uses a magnetic field to scan and collimate the beam,
providing a uniform dose and gentle thermal loading. |
|
Accelerator |
The Accelerator Module is where the ion beam
is accelerated to its final energy and focused. |
|
Terminal |
The Terminal Module houses the ion source and extraction system,
which is where the ion beam is created, and the
analyzer magnet, which selects the desired oxygen
ions. |
i2000 Implanter Benefits
- The i2000 implanter is a third-generation oxygen implantation
system designed to be a high-throughput, high-volume
production tool for manufacturing 300-millimeter
SIMOX-SOI wafers. We believe that the primary benefits
of the i2000 implanter include:
Lower cost of ownership, the ability to produce
quality SOI products, and a design that facilitates
fast installation, set up and qualification. Lower cost of ownership, as compared to
the Ibis 1000 implanter, is a result of several factors,
including higher throughput, which is achieved by using
faster load and unload cycles, rapid heating of the
wafers in the process chamber, and the use of active
cooling to cool wafers quickly after processing at very
high temperature. A higher beam current, achieved through
improved extraction optics, also enhances through put.
The smaller footprint of the i2000 implanter contributes
to lower cost of ownership by taking up less cleanroom
space. Despite its smaller footprint, the new i2000
implanter has a process chamber large enough to handle thirteen 300-millimeter
wafers.
Finally, the reliability of the i2000 implanter
keeps downtime to a minimum and maintenance costs low.
Quality products
Solid engineering throughout
the i2000 development program resulted in a machine
with minimal particle contamination—an ongoing challenge
in virtually every corner of the semiconductor equipment
industry.
The i2000 implanter is also capable of delivering a
very uniform implant dose. This implant uniformity helps
assure uniformity of the buried oxide and top silicon
layers. As the need for thinner and thinner top silicon
layers continues to emerge, we believe that the uniformity
delivered by the i2000 implanter will become more and
more important.
Features
Consistent, high-quality wafers, throughput capable of up to 24,000 300-mm wafers per year and reduced
cost of ownership are only a few of the extraordinary
features of the new i2000 implanter.
Additional Features- The i2000 implanter also
incorporates a number of features customers expect on
leading edge processing tools:
- off-hub wafer cooling
- end-station load ports that accommodate 300-millimeter wafers in
FOUP or open cassettes
- system software that supports multiple GUI's,
- remote diagnostics,
- recipe operation,
- data logging,
- SECS/GEM factory communications,
- support for SEMI safety and ergonomics standards,
and
- Ibis' patented MagScan
magnetic scanning beam technology .
