Production scheduling tool rolls for 300mm fabs

Ilog Inc. has unveiled the Fab PowerOps (FPO), touted to be the first software package to comprehensively address production scheduling for all essential front-end process areas within a 300mm semiconductor fabrication plant. Unlike other solutions, Ilog said, the FPO can create optimal, forward-looking production schedules for all tools within a given fab process area, as well as create new schedules every five minutes.

Available immediately and offered as a suite of modules, the FPO promises detailed scheduling that allows users to automatically and continuously respond to the realities of the fab environment, resulting in improved throughput, shortened hot-lot cycle times, increased tool utilization, reduced capital equipment costs and faster response times to unplanned events.

The FPO software addresses production scheduling issues across the following process areas: diffusion, photo, etch, thin films, chemical mechanical polishing (CMP) and implant. The software delivers schedules based on the evaluation of the WIP, tools, steps and process timing constraints in multiple alternative schedules before recommending the optimal schedule for a process area. With this solution, a scheduling problem can be addressed based on the real conditions of the fab environment, said Ilog, giving users more control over unplanned events, such as tool interruptions, recipe qualifications and hot lots (urgent orders). The tool can also reduce capital equipment outlay by leveraging existing capacity. In addition, the custom configuration ability of FPO means that each process can be tailored to meet the requirements of each individual customer's fab facility, the company explained.

The FPO software can also handle re-entrant flows, which is essential for photolithography process scheduling and is also important for creating better yield and quality. And because it is based on the company's visualization technology, the software not only provides superior operational visibility for users, it is also said to be the first product in semiconductor manufacturing to offer a Gantt chart display for scheduling.
