Advanced 300-mm ASIC/SOC (application-specific integrated circuit/system on a chip) fabrication plants with multiproduct and multiprocess models will require both a high level of flexibility and efficiency to achieve cost-effective manufacturing cycle times. Today, potential solutions to achieve breakthrough manufacturing cycle times are under(More)
In a worldwide environment, sustaining high yield with a minimum number of quality controls is key for manufacturing plants to remain competitive. In high-mix semiconductor plants, where more than 200 products are concurrently run, the complexity of designing efficient control plans comes from the larger amount of data and number of production parameters to(More)
In order to minimize yield losses due to excursions, when a process or a tool shifts out of specifications, an algorithm is proposed to reduce the scope of analysis and provide in real time the number of lots potentially impacted. The algorithm is based on a Permanent Index per Context (IPC). The IPC allows a very large amount of data to be managed and(More)
A qualification management software that proposes recipe qualifications on tools in toolsets for semiconductor manufacturing has been developed. The qualification proposals are based on flexibility measures that have been shown to model capacity allocation in semiconductor workshops. In this paper, qualifications are used in order to see how increased(More)
As modern manufacturing technology progresses, measurement tools become scarce resources since more and longer control operations are required. It thus becomes critical to decide whether a lot should be measured or not in order to get as much information as possible on production tools or processes, and to avoid ineffective measurements. To minimize risks(More)
Production planning in the Semiconductor Industry (SI) has emerged as the most complex process due to its process complexity, technological constraints and high-mix low-volume production characteristics. In this paper, we present two different production planning approaches, developed by STMicroelectronics and G-SCOP research laboratory, to better control(More)
In a globally competitive environment, sustaining high yield with a minimum number of quality controls is key for manufacturing plants to remain competitive. In modern semiconductor manufacturing facilities, with the moves to ever smaller geometries and the variety among products to be run concurrently, designing efficient control plans is becoming(More)
In a High-Mix/Low-Volume (HM/LV) 300mm wafer fab, several hundred product routes are active, each with dozens of Time Constraint Tunnels (TCT), the management of which has become a real challenge. In order to help addressing the difficulties it poses, a Decision Support System (DSS) dedicated to managing Line Stops of Time Constraint Tunnels (TCT) is(More)
Semiconductor fabrication plants are subject to high levels of variability because of a variety of factors including re-entrant flows, multiple products, machine breakdowns, heterogeneous toolsets or batching processes. This variability decreases productivity, increases cycle times and severely impacts the systems tractability. Many authors have proposed(More)
