In mechanisms manufacturing environment, factory management level is always trying to achieve higher product yield to ship more quality product to the customers. In this paper, we will show the yield improvement based on cycle time reduces. Yield organization has established excellent systems for driving defect reduction. Established a clear set of core principles that would help drive a new way of driving cycle time improvement. Discuss the key findings captured through yield benchmarking activities. There are three core principles outlined above and the associated changes made in manufacturing to embrace these principles.

Abstract Defect analysis and reduction is a focus in all wafer fabs, but there are many approaches to minimizing defect related yield losses. This paper describes the analysis for defect learning and our methodology for defect reduction within our manufacturing line including wafer selection, optimum allocation of engineering resources, details of the learning process, and objectives (both short and long term) of the defect analysis. The focus of the paper is on our 140nm DRAM technology products.

AbstractSuppression of arcing between the target and plasma during PVD is a key issue for defect reduction, yield improvement and high quality metallization in microelectronics manufacturing. An integrated mini sparcle product has been designed for Endura HP PVD™ sputtering sources. Characteristics of arcing and mechanisms for suppression are discussed here. Process characterization with Ti, TiN and Al sputtering proves that the arc suppression unit has little adverse impact on film properties. The uniformity of reactive sputtered TiN is improved with arc suppression. Marathon evaluation indicates significant reduction in TiN defect and Interconnect metal stack defect. The study of the application for a wide variety of materials (Al, Ti, TiN, SiW, Si) establishes a correlation between deposition rate loss and sputtering power and this relation is found to be almost independent of the materials sputtered. The impact on throughput for typical metal stack is also presented in this paper.

Synthesis of a thin, buried dielectric layer to form a silicon-on-insulator (SOI) material by high dose oxygen implantation (SIMOX – Separation by IMplanted Oxygen) is becoming an important technology due to the advent of high current (200 mA) oxygen implanters. Recently, reductions in defect densities from 109 cm−2 down to 107 cm−2 or less have been reported. They were achieved with a final high temperature annealing step (1300°C – 1400°C) in conjunction with: a) high temperature implantation or; b) channeling implantation or; c) multiple cycle implantation. However, the processes and conditions for reduction and elimination of precipitates and defects during high temperature annealing are not well understood. In this work we have studied the effect of annealing temperature on defect and precipitate reduction for SIMOX samples which were processed first with high temperature, high current implantation followed by high temperature annealing.
