AI Technical Summary

Technical Problem

On semiconductor manufacturing lines, using product batches with abnormal historical data for trial runs can easily lead to misjudgments, resulting in the official release of process equipment or formulas that actually deviate from the expected specifications. This can lead to a decrease in product Cpk, or even a decrease in product yield or scrapping.

Method used

By examining historical data of product batches and marking them according to preset conditions, suitable batches are selected for trial operation of process equipment or formulas. The Equipment Automation Management System (EAP) is used to identify and prioritize batches that meet the conditions for trial operation.

Benefits of technology

It improved the accuracy of machine or formula trial runs, enhanced the product's process capability index and yield, and avoided misjudgments caused by abnormal historical data.

Abstract

The present disclosure provides a method and system for machine trial running, the method comprising: providing a product batch; checking historical data of the product batch, and marking the product batch whose historical data meets a preset condition; determining a process machine to be trial run; and identifying and using the marked product batch to trial run the process machine to be trial run. The present disclosure checks the historical data of the product batch, and marks the product batch whose historical data meets the preset condition, filters out the process machine or process formula to be trial run, selects a suitable range of batches from the marked product batch by an equipment automatic management system to trial run the process machine or process formula to be trial run, improves the accuracy of machine trial running, improves the process capability index of the product, and improves the product yield.
