MORE THAN MOORE INDUSTRY MANUFACTURING COMPLEXITY BRINGS NEW BUSINESS OPPORTUNITIES IN BONDING AND LITHOGRAPHY EQUIPMENT MARKETS. This sector accounts today for almost 60% of the overall MtM lithography tools market and will continue dominating this industry with stepper technology. Meanwhile, a high percentage of lithography equipment. Although Sentaurus Lithography provides powerful, multidimensional analysis capabilities through its user interface, the complexity of many advanced simulation tasks requires a higher degree of automation. The MATLAB API of Sentaurus Lithography provides MATLAB users direct access to key parameters and full control over simulation runs.

Abstract

Immersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is increased by a factor equal to the refractive index of the liquid. Current immersion lithography tools use highly. Meeting the needs of EUV lithography. EUV lithography tools will be used to print features 22nm and smaller. In addition, there are calibration protocols that add to maintenance cost, downtime and operational complexity. By contrast, the Tiger-i platform of analysers from Tiger Optics eliminates the concerns arising from.

In this paper, the status of mask-less lithography for advanced semiconductor applications is reviewed. Mask-less lithography received a lot of interest as the lithography for manufacturing the critical layers of advanced integrated processes, because of the severe increase in mask costs that the industry is experiencing for critical layers as of the 45nm technology onwards. The availability of mask-less lithography would allow to get rid of these mask costs, which is in particular interesting for low volume products. First the various mask-less initiatives are reviewed, with emphasis on the European ones. The typical results that are obtained by these groups are reviewed and compared to the requirements that need to be met to become the lithography process of choice for the manufacturing of certain critical layers in advanced chips. The requirements are typically expressed in terms of resolution, overlay and throughput. A number of key conclusions are drawn : focus of mask-less tool development should be on insertion at the 16nm node, with extendibility to 11nm. Promising resolution results have been demonstrated by various groups. Today the proof-of-concept tools have not shown any overlay nor throughput performance, which needs to become the main focus for the next few years. Finally, it is recommended to focus on a parallel beam mask writer initially, where the level of complexity is much lower but most of the same challenges will need to be addressed.
