SPTS Technologies (A KLA Company)

The Sigma product range supports wafer sizes from 100mm to 300mm with deposition technologies covering conventional PVD through to MOCVD

Sigma Metal Deposition Technologies

Standard PVD – conventional sputter modules for low topography features

Advanced Hi-Fill (AHF) PVD – ionized sputter source for deposition into high aspect ratio features

C3M – Virtually conformal metal coverage using MOCVD technology for advanced liner/barrier

Advantages

Single wafer processing improves yields and on-wafer performance when compared to batch processing.

Planar target with full face erosion, avoids re-sputtering, reduces particle contamination and improves target life

Rapid target change (<5mins), with common magnetron, increases uptime

Reliable handling of fragile, thinned or bowed wafers

"Super Uniformity" option available for specialist applications

Multi-wafer degas to increase throughput for long (low temp) degas applications

Common software for 200mm and 300mm systems - ease of use

Plasma Etch

ICP Etch
The Omega® ICP process module uses a patented high density plasma source incorporating a radial coil design. The SPTS ICP process module is highly flexible and etches a wide range of materials including oxides, nitrides, polymers, low aspect ratio Si and metals. The ICP module is the market leader for compound semiconductor applications.

Dielectric Etch
SPTS’s Omega® SynapseTM process module is an ICP-based high-density plasma source, designed to etch materials which are difficult to etch using conventional RIE or ICP sources.

The process chamber is of metallic construction and is heated to reduce the level of deposition on it, thereby increasing process stability and increasing the mean time between cleans by more than a factor of 10.

Si DRIE
Install base of over 1000 DRIE process modules, SPTS’s market-leading position is spearheaded by the Rapier module, which etches Si using Bosch switched processing as well as non-switched etching for tapered profiles, wafer thinning and via reveal.
