At Semicon West, Leti
will highlight some of its latest research findings and key programs for the
semiconductor industry, including maskless lithography, FDSOI and 3D integration.
The abstracts below summarize Leti’s recent work in these areas.
Maskless Lithography
Leti and its partners in the IMAGINE program have achieved the first 32nm
resolution using multi-beam equipment from Mapper Lithography. Led by Leti,
the program is focusing on maskless lithography technology and evaluating tools
from Mapper. Partners include TSMC, ST, TOK, Sokudo and Dow Electronics. In
193nm dry lithography, the project also has achieved a 32nm half-pitch resolution
by using the spacer technique.
FDSOI
Leti will present its recent achievements regarding the capability of its
20nm planar FDSOI technology to address low-power applications. Record-matching
performance, sensitivity to SOI substrate properties, VT tuning and applicability
of low-power design techniques will be detailed during the presentations.
3D TSV
Leti is building a complete 300mm R&D line dedicated to 3D-integration
applications, including through-silicon vias (TSV). The integration line includes
lithography, metallization, deep etching, dielectric deposition, wet etching
and packaging tools that will be available for Leti’s customers and partners
around the world. The line will complement Leti’s 3D-integration toolbox,
which already includes through-silicon vias, alignment, bonding, grinding, thinning,
planarization, bumping, micro-inserts and design capabilities and mixed-signal
IC applications.
