Production process control has a great impact on cost and quality

Manually record process cards, which often lead to human error and duplication of data entry

Unable to know the status of WIP of the production line in time

Raw Wafer and ingot batching have a high error rate and large error losses

WIP data is not real-time and transparent

Unable to handle exceptions in real time and effectively

NCR / OCAP manual processing and tracking

There are many production sections and the rework rate is high, so it is difficult to calculate the cost and loss

High equipment dependence in the production process, high maintenance and control requirements
