The AccuThermo AW820 was derived from the AG Associates 610 production-proven design. Allwin21 Corp. is the exclusive manufacturer of the AG Associates Heatpulse 610 desktop atmospheric RTP (Rapid Thermal Processing) system. The system uses high intensity visible radiation to heat single wafer for short process periods of time at precisely controlled temperatures. The process periods are typically 1 600 seconds in duration, although periods of up to 9999 seconds can be selected. These capabilities, combined with the heating chamber's cold-wall design and superior heating uniformity, provide significant advantages over conventional furnace processing.

AccuThermo AW 820 Software Key Features:
Integrated process control system
Real time graphics display
Real time process data acquisition, display, and analysis
Programmed comprehensive calibration and diagnostic functions
Closed-loop temperature control with temperature sensing.
Precise time-temperature profiles tailored to suit specific process requirements.
Faster, easier Programmable comprehensive calibration of all subsystems, leading to enhanced process results.
A recipe editor to create and edit recipes to fully automate the processing of wafers inside the AccuThermo RTP
Validation of the recipe so improper control sequences will be revealed.
Storage of multiple recipes, process data and calibration files so that process and calibration results can be maintained and compared over time.
Passwords provide security for the system, recipe editing, diagnostics, calibration and setup functions.
Simple and easy to use menu screen which allow a process cycle to be easily defined and executed.
Troubleshooting feature which allows engineers and service personnel to activate individual subassemblies and functions. More I/O, AD/DA “exposure”.
Use PowerSum technology to detect the process and increase Yield.
Watchdog function: If this board looses communication with the control software, it will shut down all processes and halt the system until communication is restored.
GEM/SECS II function (Optional).
