SI 500 PPD (PECVD) with load lock

The SI 500 PPD represents an advanced tool for plasma enhanced chemical vapor deposition of dielectric films, a‑Si, SiC, and other materials. It is based on planar capacitive coupled plasma source, vacuum load lock, temperature controlled substrate electrode, optional available low frequency mixing, fully controlled oil-free vacuum system, advanced SENTECH control software using remote field bus technology, and a very user friendly general user interface for operating the SI 500 PPD.

A large variety of substrates from wafer up to 200 mm diameter to parts loaded on carriers can be processes in the SI 500 PPD plasma deposition tool. The single wafer vacuum load lock guarantees stable process conditions and allows easy switching of processes.

The SI 500 PPD plasma enhanced deposition tool is configured to deposit SiO₂, SiN_x, SiON_x, and a-Si films in a temperature range from room temperature up to 350 °C. Solutions are available for the deposition of TEOS, SiC, and other materials with liquid or gaseous precursors. The SI 500 PPD is suited for the chemical vapour deposition of dielectric films and amorphous silicon for etch masks, membranes, passivation films, waveguides, and others.

SENTECH offers different levels of automation ranging from vacuum cassette loading to one process chamber up to six port cluster with different deposition and etch modules targeted to high flexibility or high throughput. The SI 500 PPD chemical vapour deposition system is available as process module on cluster configuration as well.
