spacer No-Wait-ManufacturingSM Vision

No-Wait-Manufacturing is a vision for a family of products and services which reduce or eliminate the unnecessary ‘waits’ or delays.


 Specifically, Aquest’s No-Wait-Manufacturing solutions significantly improve Fab productivity, by reducing Fab cycle-time and improving equipment utilization as well as increasing flexibility of Fab layout and expansion in an IC Fab. spacer

No-wait-prod-Improvementspacer

The FabEX No-Wait-Productivity Improvement optimizes material movement in an existing Fab, by eliminating or minimizing bottlenecks that are impacting Fab productivity. Most Fabs have some areas where the existing OHT or OHS based automated material handling systems (AMHS) cannot keep pace with the demands of the Fab. These bottlenecks and traffic jams steal productivity from the Fab. Adding a FabEX Highway eliminates the bottleneck and moves FOUPs at 3 meters per second between interface locations including stocker and OHT input/output portsspacer

  • Interfaces directly with installed OHT based AMHS and Stockers
  • Typically installs directly below existing, installed OHT system
  • Interfaces to existing Fab material control system (MCS) software, via industry standard SECS interfaces
  • No need to stop production to install the FabEX based improvement

Example applications include

  • Fab building interconnection
  • Fab module interconnection
  • Wafer start/final test
  • High throughput bay
  • Remote Fab areas
  • Multi-AMHS interconnection
  • Stocker to bay feed
  • Full Interbay

spacerFabEX™ Transporter

The FabEX Transporter utilizes patented* technology to create fast (3m/s), high capacity FOUP transportation. FabEX Transporter is significantly faster than conventional AMHS built from conveyors or overhead hoist vehicles. It also has the ability to move around curves and ramps, while minimizing vibrations with minimal particle generation. Finally, since FabEX does not need any vehicles, it provides the high capacity afforded by conventional conveyor systems. All of this, coupled with sophisticated internet-protocol (IP) technology-based controls and software, enable seamless integration into semiconductor Fabs.

FabEx

Another unique aspect of the FabEX technology is its inherent simplicity. With significantly fewer moving parts than conventional AMHS vehicles or conveyors, it is designed to deliver higher reliability and a lower cost of ownership. And by reliably and predictably increasing the number of moves per hour, FabEX allows users to optimize lot sizes and increase their Fab productivity.
