| New Nikon Software Improves Yield by Identifying
Likely-to-Fail Die. Software Runs on Enhanced NEST Manager Operating
System for I-line and G-line Imaging Tools.
Belmont, California, January 18, 2001 -Nikon
Precision Inc. (NPI) has released its first application software
product that helps improve yield for imaging tools by identifying
where die are likely to fail. The software, called Hot Spot Detection,
runs on the improved NEST™ (Nikon Enhanced System Technology)
Manager operating system for the company's model 6-10 i- line
and g-line steppers.
The software enables focus data collection at each die and statistical
wafer mapping of that data to detect the presence of a particle
on the wafer chuck. The results can be sent to a host computer
to automatically stop the lot, saving considerable rework expense.
The newly released NEST Manager upgrade, which reduces overhead
up to 200 percent, offers an improved Windows NT graphical user
interface (GUI) and additional functionality over previous versions
of NEST. These features combined with the improved data processing
capability of NEST, provides customers with increased wafer output
from their existing production capacity. "Nikon Precision is
continuing its efforts to assure the success of its customers
by offering upgrades to enhance the performance and prolong the
life of our installed base of imaging systems," states Chris
Hayden, Nikon's senior manager of after-market operations. "In
addition, our software department is developing other applications
similar to Hot Spot Detection that will identify problems such
as alignment shift that lead to yield loss," he added.
NEST Manager monitors the operation sequence of the imaging tools.
Detailed sequence monitoring information and process parameters
are logged into a file for use in analyzing machine performance,
resulting in improved diagnostic capability and more efficient
troubleshooting. NEST also can generate a snapshot of daily process
history, making it possible to easily review machine utilization
and throughput.
