A major independent device manufacturer has placed a multi-system
purchase order with RAVE for its ‘Rhazer’ haze removal systems for
reticles. The orders were given after an extensive in-fab evaluation of
the Rhazer haze removal technology, according to RAVE.

Product Briefing Outline: Applied Materials has introduced its
new ‘Applied Centura Tetra’ EUV Advanced Reticle Etch system. The new
systems is claimed to overcome a major hurdle to the adoption of EUV
lithography by solving the critical and unmet challenge of etching EUVL
photomasks with nanometer-level accuracy and world-class defect
performance to enable the fabrication of multiple new generations of
high-performance semiconductor chips at the 16nm node and below.

Product Briefing Outline: Brion Technologies, a division of ASML,
has launched a new product for its Tachyon computational lithography
platform. Tachyon MB-SRAF (Model-Based Sub-Resolution Assist Features)
is said to enable the high-speed, full-chip processing of advanced chip
designs with larger process windows, greater productivity, and lower
development costs than rule-based alternatives.

ABSTRACT
The paper presents a calculation model and conclusions with focus on the comparison of low-throughput and high-throughput lithography clusters via an analysis of the lithography Cost of Ownership (COO) and applied data of the Overall Equipment Efficiency (OEE) and Overall Factory Efficiency (OFE). The report will show that the published documents up to today are not sufficient to prove that a higher throughput necessarily leads to an advantage of the manufacturing effectiveness and that it is necessary to calculate and adapt it onto the chip manufacturer’s requirements. It will show metrics and a methodology for fab planners and equipment engineers to calculate the needed cluster throughput and to optimize the lithography efficiency. Furthermore, the calculation model presents a flexible method to identify not only the key drivers to run an efficient production, but also to easily compare different scenarios. Two examples are shown, with models evaluated with real data. This study might also be applicable to other semiconductor processing steps.
By Bernardo Kastrup, ASML, Veldhoven, The Netherlands - ABSTRACT - Feature shrink is the force that drives the semiconductor industry forward. At each step along the technology roadmap, manufacturers need to be able to produce chips efficiently, cost effectively and with high yield. As feature sizes become ever smaller, the manufacturing challenges increase almost exponentially, putting extremely tight requirements on parameters such as overlay and critical dimension uniformity (CDU). Even the tiniest process variation can have a potentially disastrous effect. In order to remedy these challenges, this paper’s proposal for a holistic manufacturing approach claims to avoid these effects by looking at all of the essential steps and processes together as a whole.
