S/TEM provides <1.0Å resolution for nano applications
 |
The Titan 80-300 scanning/transmission electron microscope (S/TEM) is dedicated to corrected microscopy. The S/TEM system yields atomic-scale imaging with TEM information limits below 0.7Å and S/TEM resolution <1.0Å without the aberration-corrector upgrades. The Titan’s upgradeability will enable corrector and monochromator technology to be used in nanotechnology research and industrial markets. Corrector upgrades can be added for higher resolution, extending the point resolution down to the information limit for accurate interpretation of atomic structures, and allowing end users to expand the system’s resolution limits as their requirements change.

System delivers low-energy implants for transistor scaling to 90nm and beyond
 |
The VIISta HC single-wafer ion implanter is designed for low-energy implant applications in sub-90nm processing.

The 6800 reduces microscopic systematic deviations in CCD/CMOS image-sensor masks. New optics improve CD linearity and clearfield/darkfield deviation, and a bias method enhances CD accuracy for all angles, important for X-design interconnects and other designs with angled features. The platform is suitable for volume manufacturing of advanced photomasks, and provides laser pattern-generation capability for advanced semiconductor, image sensor, and display photomasks.

Two-in-one inspection tool automatically classifies and responds to defects
 |
The LDS3300 C system combines simultaneous micro-and macrodefect detection for 200-300mm wafer applications. The system performs automated defect detection, classification, and inline review of the entire wafer surface. Variations considered defects are compared to an image library of known classified defect groups; then the system individually decides further steps. The microscope module has a multiwavelength design for 80nm resolution. Leica Microsystems, Wetzlar, Germany; ph 49/6441-29-2229, fax 49/6441-29-2325, e-mail [email protected], www.semiconation.com.
Bonder offers 87% faster bumping at 60µm pitch
 |
The ATPremier stud-bumping machine offers greater stud-bumping speed, lower impact force, and finer pitch capability for the flip-chip market. The bumper bonds 36 standard bumps/sec at 60µm pitch - an 87% speed improvement over the previous platform. Because stud bumping does not require under-bump metallurgy, bonding can be performed in a single step. The new wafer-mapping interface bonds only known good die instead of the entire wafer, decreasing materials consumption and processing time. Step-and-repeat teaching keeps the bonder producing product, rather than teaching programs.
