EX-300

CAMECA's new generation Shallow Probe: the metrology solution for advanced integration of new processes.

The EX-300 benefits from over a decade of experience with LEXES technology in the semiconductor industry: dozens of LEXFAB-300 Shallow Probes have been installed at the top-ten semiconductor fabrication facilities worldwide. The EX-300 is targeted for new challenging applications such as SiGe and HKMG, and it is designed to accelerate the time to market of advanced logic & memory devices while achieving high production yield.

The tool of choice for front-end process issues at 32nm node and beyond

The non-contact, non-destructive LEXES technique is a unique solution for direct measurement of the chemical composition at the surface and near surface.

hkmg-metrologyThe EX-300 offers a panel of complementary capabilities enlarging the domains of classical metrology to current challenging processes: 

> Ultra shallow implants: Monitoring of low energy, high concentration implants.

> Strained silicon process control: Chemical composition and thickness in epitaxial layers such as B:SiGe and P:SiC, with no limitation in the layer composition.

> HKMG metrology: Both the oxydes and the metal are controled by one single EX-300 platform.

CAMECA's EX-300 delivers enhanced long-term stability with better vacuum limit. The below graph shows reproducibility over several months for an average As dose of 1.97e15 at/cm2 with a global RSD (1σ) of 0.622%.

ex-300-tool-designAdvanced and robust pattern analysis

The EX-300 has been specifically designed to perform metrology of challenging patterned wafers down to 30x30µm pads.

Higher brightness is achieved with the new LaB6 gun, thus ensuring denser small probe. Improved light source and optics and a new digital camera with zooming capabilities enable smooth visual navigation while the new electrostatic chuck secures wafer clamping.

Optimized design and easy tool control for high uptime

The EX-300 delivers 5 to 20% throughput  improvements compared to the previous Shallow Probe LEXFAB-300 model (depending on application). Improved ergonomics allow rapid maintenance and thus optimized MTTR. The fully integrated LEXES-Pilot software provides a user-friendly interface as well as reliable factory automation.
