| The customer |
| A leading semiconductor processing
equipment manufacturer based in USA producing a
wide range of equipments covering the different
stages of the silicon wafer processing |
| |
| Challenges |
| Wipro’s association with
the client started in Feb 2001. Since then Wipro
has been involved in developing new products, and
supporting the existing products. The client was
new to the concept of software outsourcing of critical
control systems. The software engineering processes
of the client were not well established. Wipro’s
lack of domain knowledge was one of the weak areas.
The challenge was to establish a system where the
client could outsource critical components of the
software development and maintenance |
| |
| Solution |
 |
Enhancement
of complex sequencer algorithm for improving
the performance |
|
Development
of XML framework for Gas Panel Configuration
and MSXML DOM parser |
|
Development
Generic control software for Lifter |
|
Implementation
of software interlocks for UPS management |
|
The offline
recipe editing software for the client, with
a user-friendly GUI |
|
Protocol driver
development for factory interface of factory
automation |
|
Simulation
of different devices like Convectron, Manometer,
Ion Gauge to cover larger pressure range |
|
Software development
for co-ordination for the wafer movement,
operation between mainframe robot and chamber
lifter |
|
Application
development for devices in chamber, communicating
on DeviceNet |
| |
Maintenance of control
software on Boss OS running on Motorola 68000
microprocessor |
|
| |
| Benefits to customer |
| Within a short span the client
has gained the confidence to outsource work on critical
real time modules such as process chambers, motion
controllers, lifters, pressure subsystems, gas panels,
factory automation, host control, etc. The work
is extended to other geographies (UK) also. The
client has benefited from Wipro’s strong processes
and self-initiatives like six sigma. Wipro’s
processes has resulted in faster development of
the products like simulators, seamless upgrades
of the legacy systems to the new technologies, etc. |
