AI Technical Summary

Technical Problem

Existing multi-channel mass flow controller systems suffer from millisecond-level timing jitter and difficulties in data correlation during synchronization and data interaction, leading to a decrease in thin film deposition uniformity and interface quality.

Method used

The system, built with an embedded MCU and a TSN switch, employs a device access module, a command synchronization module, a data marking module, a data allocation module, and a timing feature monitoring module. It achieves nanosecond-level synchronization control and millisecond-level data alignment. Combined with an error model and a time series alignment algorithm, it eliminates timing jitter and ensures data traceability.

Benefits of technology

Nanosecond-level synchronous start-stop control of a multi-channel mass flow controller was achieved, reducing pulse waveform distortion, improving thin film deposition uniformity and interface quality, while solving the problem of data correlation and improving system reliability and data analysis accuracy.
