For Sale: AccuThermo AW 610V Vacuum RTP

AccuThermo AW 610V SYSTEM DESCRIPTION

AccuThermo AW 610V  is a manual desktop vacuum rapid thermal processing (RTP) system for 2 to 4 inch or 4 to 6 inch wafers, which uses high intensity visible radiation to heat single wafers for short process periods of time at precisely controlled temperatures and vacuum. 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.The AccuThermo RTP system consists of an oven unit and a controller computer running the Advanced Allwin21 AW-900 controller software. The wafer to be processed is placed on a quartz tray that slides into the chamber with quartz window plate in the oven unit. The lamps above the quartz window provide the source of energy for heating the wafer. The lamps can be controlled manually and automatically from the controller computer.

1. Vacuum
2. Closed-loop temperature control with pyrometer or thermocouple temperature sensing.
3. Precise time-temperature profiles tailored to suit specific process requirements.
4. Fast heating and cooling rates unobtainable in conventional technologies.
5. Consistent wafer-to-wafer process cycle repeatability.
6. Elimination of external contamination.
7. Small footprint and energy efficiency.
8. The watchdog timer shuts down the lamps to prevent run-away heating of the wafer.

1. The AccuThermo RTP system is a versatile tool that is useful for many applications:
2. Ion Implant Activation
3. Polysilicon Annealing
4. Oxide Reflow
5. Silicide Formation
6. Contact Alloying
7. Oxidation and Nitridation
8. GaAs Processing

1. High-intensity visible radiation heats wafers for short periods of 1 to 9999 seconds at precisely controlled temperatures in the 400°C to 900°C range. (1 to 600 second heating periods are used typically.)
2. Tungsten halogen lamps and cold heating chamber walls respectively allow fast wafer heating and cooling rates.
3. The system delivers time and temperature profiles tailored to suit specific process requirements.
4. Pyrometer or thermocouple sensing offers precise closed-loop temperature control.
5. Cooling N2 flows around the lamps and quartz isolation tube
6. MFC controlled gases (up to six) flow through the heating chamber for purge and/or process purposes.

1. Vacuum: vacuum
2. Wafer handling: Manual loading of wafer into the oven, single wafer processing.
3. Wafer sizes: 2", 3", 4" or 4",5" 6" wafers.
4. Ramp up rate: Programmable, 10°C to 200°C per second.
5. Recommended steady state duration: 0-300 seconds per step.
6. Ramp down rate: Programmable, 10 C to 100 C per second.Ramp down rate is temperature-and-radiation-dependent and the maximum is 125 C per second.
7. Recommended steady state temperature range: 150°C - 900C
8. ERP temperature accuracy: ±1°C, when calibrated against an instrumented thermocouple wafer (ITC).
9. Thermocouple temperature accuracy: ±0.5°C
10. Temperature repeatability: ±0.5°C or better at 1150°C wafer-to-wafer. (Repetition specifications are based on a 100-wafer set.)
11. Process/Purge gas inputs: Any inert and/or non-toxic gas regulated to 30 PSIG and pre-filtered to 1 micron. Typically, Nitrogen (N2), oxygen (O2), argon (Ar), and/or helium (He) are used.+2.5°C
