Applied Materials 0190-26463

Product Description

0190-26463 is a high-precision thermal controller module developed by Azbil(Yamatake) for Applied Materials Centura Silvia and Vantage RadiancePlus 300mm semiconductor platforms. It is a dedicated temperature control unit for RTP (Rapid Thermal Processing) chambers, responsible for precise thermal loop regulation of wafer pedestal and heater assembly during high-temperature semiconductor thermal processes.

Product Functions

• Collects temperature input signals from multiple thermocouple sensors installed on wafer pedestal and heating lamps.
• Implements advanced multi-channel PID closed-loop control to stabilize wafer surface temperature with high accuracy during rapid thermal processing.
• Outputs drive control signals to adjust lamp power, maintain uniform temperature distribution across wafer surface and avoid thermal gradient defects.
• Implements over-temperature safety interlock and communicates with chamber controller, transmitting temperature data, thermal status and fault alarms for recipe monitoring and protection.

Application Scenarios

• Applied Materials Centura Silvia and Vantage RadiancePlus 300mm wafer processing platforms.
• RTP rapid thermal processing vacuum chamber thermal control subsystems.
• Semiconductor fabs for annealing, thermal activation and high-temperature thin-film manufacturing processes.

Frequently Asked Issues

• Temperature reading drift: Aging signal conditioning circuits cause thermocouple offset, leading to wafer temperature non-uniformity and recipe shift.
• Thermal control oscillation: PID parameter drift or sensor noise triggers temperature fluctuation and poor thermal uniformity.
• ESD damage: Improper electrostatic protection during handling burns signal conditioning and logic circuits.
• PCB contamination: Process vapour residue creates leakage paths and causes intermittent temperature measurement failure.
