Spectra Series

SPECTRA G

The Spectra-G is a cost-effective, high performance exhaust treatment solution for nitride MOCVD manufacturing.

Technology

4 Stage Combustion

The unique 4-stage combustion system of the Spectra-G ensures that oxidation of silane occurs in the middle of the combustion zone, away from the inlets, hence preventing the deposition of oxide powders on the combustor nozzles and maximizing uptime.

Effective Powder Handling System

The oxide powders generated by the combustion of metalorganics are entrapped in the cooling air stream that is introduced in the Spectra-G at a velocity of 10 m/sec.

Air flow is generated by the house extraction system. This air-cooled design ensures that combustion by-products are efficiently transported from the Spectra-G to the factory central scrubber or dust filter.

Optimum Combustion

Nitride MOCVD processes involve the use of high H2 and NH3 flows. The Spectra-G utilizes the inherent flammability of these gases to minimize the additional fuel required to complete the gas abatement reactions (oxidation). Different fuel types are available to suit customer requirements.

The high gas capacity of the Spectra-G allows up to six production MOCVD tools to be connected. Each individual inlet allows each exhaust to act independently, thereby reducing capital and running costs.

SPECTRA Z

The Spectra-Z system is a cost effective, reliable, high performance exhaust treatment solution for the latest generation Flat Panel Display (FPD) and Solar Cell manufacturing processes.

4 Stage Combustion

The unique 4-stage combustion system of the Spectra-Z ensures that oxidation of silane occurs in the middle of the combustion zone, away from the inlets, hence preventing the deposition of silica powders on the combustor nozzles.

Effective Powder Handling System

The powders generated by the combustion of SiH4 and PH3 are entrapped in the cooling air stream that is introduced in the Spectra-Z at a velocity of 10 m/sec. Air flow is generated by the house extraction system. This air-cooled design ensures that combustion by-products are efficiently transported from the Spectra-Z to the factory central scrubber or dust filter.

By-Product Destruction

In the Flat Panel CVD 8 solar cell process hydride gases SiH4, PH3, NH3) flow through the process chamber. The Spectra-Z abates these gases and related by products in a cost efficient manner by operating at an optimized fuel rate.

User Friendly System

Ease of use - The Spectra is configured, monitored and controlled via a large touch-screen display. Fourgauges display the fuel gas and extraction pressures.

Component Accessibility - Designed for fast maintenance - all electrical components are accessible from the front of the Spectra and all mechanical components are easily accessible from the left side of the system.

Easy communication - The PLC and built-in computer of the Spectra allow easy communication with the vacuum pumps, the process tool and the factory monitoring system.
