Fab Automation and Productivity
With increasing cost of tools and Fabs, the cost of ownership is assuming a very important factor in the Semiconductor industry. Satyam offers solutions that increase the productivity and reduce the total cost of ownership (TCO) for the Fabs and equipment manufacturers.
Preventive & Predictive Maintenance (PPM) Solution
This is a critical enabling capability for Fabs to enhance their Overall Equipment Efficiency and reduce unscheduled downtime providing early warning of failures. A predictive solution for tool and Fab maintenance helps in:
- Reducing unscheduled downtime
- Increasing consumables lifetime & utilization
- Reducing process drift
To make predictions that are useable in a real factory, there are four essential components—Input, Methodology, Output, and Use—that make the maintenance of equipments resolute. In any case, predictive maintenance is complementary to condition-based preventive maintenance.
Features and Benefits:
- Powerful Predictive Analytics & Improved CBM techniques
- Engineering data for corrective action
- MTBF, MTTR, Fault/Detection Classification etc.
- Automatic identification of pending failures by the process tool
- Patterns for deficiencies and data mining for statistical analysis
- Addresses both EDA and legacy tools across cross technologies
Intelligent Scheduling & Dispatch Solutions
According to the International Technology Roadmap for Semiconductors (ITRS, 2003), the cost of equipment is over 75% of factory capital costs. The ITRS indicates that, in order to utilize this equipment effectively, significant improvements in factory planning and scheduling are required. Intelligent Scheduling & Dispatch Solutions create optimal, forward-looking production schedules for all tools within a given Fab process area.
Existing solutions in the market are dispatcher-based and cannot take care of complex Fab scheduling. Satyam has developed an optimal scheduling solution SIRIS, based on modern stochastic optimization techniques along with its alliance partner, Optessa. The Satyam-Optessa Fab productivity system for scheduling semiconductor manufacturing is a specially configured version of Optessa MLS sequencing and scheduling system. Optessa has proven algorithms that use modern stochastic search techniques to rapidly find a near optimal solution, even for large problems.
Features and Benefits:
- Built on a proprietary engine
- Superior to the conventional rule based /constraint based solutions
- Upstream/Downstream WIP and Tool Balancing
- Searches the solution space in a fast and efficient manner
- Intelligently handles the unique requirements of the Fabs such as Re-Entrant Flow, Hot Lots, Tools Matching
- Increases throughputs of Equipments and Fabs
