Product Briefing Outline: Applied Materials has
launched the ‘Applied Producer Celera' PECVD system, which is designed
to handle advanced strain engineering technologies for enabling faster
transistors in 45nm-and-beyond devices. The Producer Celera enables
improved transistor drive current by applying a uniaxial stress in the
device channel.
Problem: Multiple strain engineering films are
typically used in advanced devices to increase the transistor drive
current and thus optimize their speed and power performance. Strain
films, combined with new high k/metal gate technologies, will extend
chip scaling beyond the 45nm node and enable the continuation of
Moore's Law.
Solution: By integrating
Applied's proprietary ‘Nanocure UV' cure technology with an enhanced
nitride deposition chamber, the system increases film tensile stress by
more than 30 percent, to 1.7GPa, with extendibility to exceed 2.0GPa,
according to the company. The same deposition chamber can deposit films
with compressive stresses up to 3.5GPa for >85 percent improvement
in drive current when used with SiGe recessed source/drain structures.
Key to the Producer Celera system is its integrated multi-step
deposition and cure process that is claimed to have the highest PECVD
tensile stresses in NMOS devices. The entire process is performed in
situ, without exposure to air, improving device reliability and
performance, according to the company.
Applications: Compressive and tensile high-stress silicon nitride films for strain engineering.
Platform:
The Applied Celera deposition and UV cure processes are integrated on
the production-proven, high-throughput Producer platform. With its
flexible Twin Chamber configuration, the Producer platform enables
integrated multi-step deposition and UV cure process capability for
improved transistor performance and reliability. Both tensile and
compressive stress films can be deposited in the same Twin Chamber for
process flexibility, and platform extendibility enables customers to
leverage the Producer toolset for multiple process nodes.
Availability: May 2007 onwards.
