AI Technical Summary

Technical Problem

The cold wall design of traditional rapid heat treatment equipment leads to the problem of contaminant redeposition. Existing cleaning methods cannot adapt to the differences in contaminants generated by different processes, resulting in insufficient or excessive cleaning. Furthermore, offline cleaning reduces equipment utilization.

Method used

The plasma in-situ cleaning method is adopted. Through intelligent monitoring and dynamic adjustment of the cleaning process, the cleaning parameters, including gas supply flow rate, power supply operating parameters and exhaust flow rate, are dynamically adjusted based on the contaminant parameter information and historical process type by utilizing the plasma generation unit, cleaning gas delivery component and exhaust component, thereby achieving efficient cleaning of the heat treatment chamber.

Benefits of technology

It effectively reduces the accumulation of pollutants in the heat treatment chamber, prevents the redeposition of pollutants caused by the cold wall effect, improves equipment utilization and cleaning efficiency, and avoids resource waste and equipment damage.

Abstract

本申请涉及热处理设备清洗技术领域,具体提供了一种等离子体原位清洗方法、设备及存储介质,方法包括步骤:根据上次清洗后热处理工艺的执行次数和污染物参数信息分析是否需要对热处理腔室进行清洗;根据历史热处理工艺类型和污染物参数信息确定气体供应流量、电源工作参数、排气流量和单次清洗时长;根据气体供应流量向热处理腔室内输送清洗气体;在热处理腔室内的压力达到预设压力范围后,开始计算清洗时长,根据电源工作参数控制脉冲射频电源向射频电极提供对应的脉冲信号,以将清洗气体电离成等离子体,并根据排气流量控制排气组件工作,以将等离子体与污染物形成的副产物气体排出;方法能够有效减少热处理腔室内的污染物积累。
