Paper Abstract

Technical problems with shrinking process node for semiconductor manufacturing has generated considerable interest in the use of multiple beams as an advance manufacturing technique in the context of direct write to mask / wafer. This paper examines the data preparation bottlenecks associated with this process. The various steps in the data preparation flow are described. Particular attention is paid to the large increase in data volume and the associated issues in processing power, transfer speed, storage requirements, and overall turn-around-time. Further, the use of commercial graphic processing units (GPUs) is examined as a possible solution to some of these issues and results of tests conducted as part of the MAGIC (MAskless lithoGraphy for IC manufacturing) initiative are summarized.
