 Product Briefing Outline: FabTime Inc has released
Version 6.2 of their cycle time management software for semiconductor
wafer fabs. Version 6.2 is now installed and running 24 hours a day at
all FabTime customer sites.
Problem: FabTime is designed for hands-on use by managers
and supervisors, unlike traditional reporting tools, which were
designed for programmers. Typically, fab manufacturing execution
systems generate reports on a daily, or even weekly, basis. From these
reports, one can sometimes determine where the cycle time problems
were. The cycle time management system shows where cycle time is
accumulatingin real time, so that corrective action can be taken
immediately.
Solution: FabTime is a web-based digital dashboard
designed to give wafer fab managers the information that they need, in
real-time, to help run their fabs effectively. FabTime extracts
operations data (moves and tool state transactions) from the fab
manufacturing execution system (MES) every five minutes, and makes the
data available via web browser from anywhere within the corporate
Intranet. The software includes a standard, pre-defined set of charts,
reflecting performance measures that FabTime's founders have found to
be useful in understanding and improving fab performance
Applications: All 200mm & 300mm fabs.
Platform: Version 6.2 includes, integrated capacity
planning based on changes in product mix and line yield (and using
actual process flow and tool uptime data). Colour-coding of WIP lot
list charts (to indicate on hold vs. in queue vs. in process). Reverse
cumulative WIP data by process stage (to quickly locate shipment
pull-points). Now has the ability to mix FabTime slide show charts and
external web content using a web-screen-saver. Automatic breakdown of
standby time into "standby- WIP-waiting" and "standby-other". New WIP
utilization outputs on tool state charts. Support for fractional hour
periods on all trend charts and dynamic x-factor trend and pareto
charts.
Availability: November 2004 onwards.
