Related Models & Series

The 0190-28658 belongs to the Verity SD1024 family of smart spectrometers. Other models often found in the same tool clusters include:

SD1024G: High-resolution variants.

SD1024F: Standard precision for industrial plasma etch.

0190-26514 / 0190-29889: Associated fiber optic and controller modules used in the same signal chain.

Application Cases

This unit is predominantly used in Applied Materials Etch and CVD systems, such as:

AMAT Centura/Endura Platforms: For monitoring thin-film thickness and plasma consistency.

DPS II (Decoupled Plasma Source): Used for real-time Endpoint Detection (EPD) to stop the etching process precisely when a specific layer is reached.

Fault Detection: Identifying chemical shifts or impurities in the chamber during a production run.

Product Advantages and Features

High Sensitivity: Designed to detect minute changes in plasma emission spectra.

Real-time Processing: Integrated controller (EyeD™) allows for immediate data interpretation without lagging the tool's PLC.

Robust Integration: Seamlessly interfaces with Applied Materials proprietary software for automated recipe control.

Compact Design: Designed for "on-tool" mounting to minimize signal loss through fiber optics.

Installation and Maintenance

Installation: Requires a dedicated fiber optic cable (0190-19764) and proper alignment with the chamber viewport. 

The unit must be secured to the tool frame to prevent vibration-induced signal noise.

Maintenance: * Calibration: Periodic wavelength calibration is required using standard gas emission lines.

Cooling: Ensure the unit’s integrated heat sinks or fans are free of dust to prevent CCD thermal noise.

Fiber Integrity: Inspect the fiber optic tips for scratches or "clouding" caused by UV exposure from the plasma.

Unique Product Description

The AMAT 0190-28658 is more than just a sensor; it is the "eyes" of the semiconductor chamber.

While most sensors measure pressure or flow, this spectrometer "sees" the chemical reactions as they happen.

By breaking down the light from the plasma into 1.024 distinct points of data,

it allows engineers to see the exact moment a layer of silicon or metal is cleared, ensuring nanometer-scale accuracy that is impossible to achieve with timers alone
