AMAT 0190-14928 SCR Power Controller (PVD Reverse Zone)

AMAT 0190-14928: SCR Power Controller (PVD Reverse Zone)

The AMAT 0190-14928 is a high-precision SCR (Silicon Controlled Rectifier) Power Controller, primarily manufactured by Control Concepts (Model 3096-2002) for Applied Materials (AMAT).

It is a critical electronic module used to manage resistive heating elements within PVD (Physical Vapor Deposition) chambers.

Specifically, it is utilized for Reverse Zone Heating and ESC (Electrostatic Chuck) Bakeout processes, providing proportional power control to maintain rigorous thermal uniformity.

Technical Parameter Table

Product Advantages and Features

Thermal Precision: Provides smooth, flicker-free power adjustment, which is essential for the delicate temperature ramping required during wafer bakeout.

Closed-Loop Feedback: Interfaces with the system controller to provide real-time monitoring of current and voltage, ensuring the heater matches the process recipe exactly.

Industrial Reliability: Engineered to withstand the high-duty cycles of semiconductor fabrication, where downtime can cost thousands of dollars per hour.

Compact Integration: Designed for rack-mounting within the AMAT tool’s AC distribution box or controller chassis.

Unique Product Description

The AMAT 0190-14928 acts as the high-current "muscles" behind the chamber's thermal logic. While the mainframe dictates the recipe, this SCR controller executes the power delivery with micro-second accuracy.

By utilizing high-quality thyristors, it avoids the mechanical wear associated with traditional contactors, providing a silent, long-lasting solution for managing the intense heat required for Physical Vapor Deposition and Electrostatic Chuck maintenance.

Application Cases

PVD Reverse Zone Heating: Managing the temperature of the chamber walls or shields to prevent precursor condensation.

HTBESC Bakeout: Providing controlled power to high-temperature electrostatic chucks during the conditioning phase to remove moisture or contaminants.

Resistive Heater Control: Any single-phase 208V heating application within the Centura or Endura platforms where precise proportional control is required.

Installation and Maintenance

LOTO Protocol: This module operates at 208V AC. Ensure Lockout/Tagout procedures are strictly followed before opening the AC box for installation.

Thermal Interface: Ensure the mounting surface is clean and that any required thermal paste or pads are in good condition to allow the heat sink to dissipate energy efficiently.

Wiring Integrity: Inspect high-current terminals for signs of oxidation or pitting. Loose connections can lead to localized overheating and premature board failure.

SCR Testing: If the heater fails to reach temperature, check the SCR for "short" or "open" states using a multimeter; these components can be sensitive to voltage surges.
