| KLA-Tencor produces
advanced semiconductor wafer inspection instruments. Products
are used to improve yields critical to profitability when developing
ICs. Project development emphasis was on real time control,
and reliability. With instrument pricing in the $100,000s supporting
production lines costing millions, minimal down time is understandable.

| Flexus |
Project
Lead |
|
| The Flexus product
line of products measures a wafer's characteristics under heat
stress. Lasers are used to measure warping and irregularities.
Results report individual "bad" wafers and can show "bad" processes
by the way they failed. As lead of a small team, we improved
reliability and throughput, added features to evaluate new characteristics,
and support for new wafer form factors. |

| Profiler |
Developer |
|
| The Profiler product
line measures height characteristics using a microfine stylus
with a featherlight touch. This approach can reveal whether
etched features such as electrical contacts penetrated deep
enough to reach the next layer. Highly automated after training,
the instruments can be set to do statistical sampling or to
scan each die in the wafer. Pattern recognition is used to find
sites of interest. |

WinMac had many responsibilities among them the
following.
 Infrastructure code to support connections to many submodules.
Support for new hardware such as automated wafer loaders and smaller die features.
New graph and statistical report displays and hard outputs.
Improved reliability and defect repairs.
Conversion from flat file to database storage, database support coding.
Port of Windows versions.
Use of Windows NT porting (threads, IPC) for real time
functionality.
Software security system.

| Flat Panel |
Lead
Developer |
|
| This product line
measures glass flat panel displays for defects. Similar to the
Profiler line, differences include the larger dimensions of
the "wafer" and its features. WinMac was tasked to improve reliability
and to add some features. In one notable incident, I resolved
bugs in the software saving $1.8 million dollar worth of orders
from cancellation. |
