1. A process data detection method, performed by an electronic device calling a program, the electronic device comprising a display, wherein the detection method comprises:
determining process data of a new process;
according to the process data of the new process, detecting, by a first production system, whether a wafer carrier type of the new process matches an acceptable level of a corresponding process step or not and whether the new process matches a flag of the corresponding process step or not;
if not, determining that the process data does not pass the detection and automatically popping up, on a present interface of the display, a prompt box containing first detection information in text form; or
if the wafer carrier type of the new process matches the acceptable level of the corresponding process step and the new process matches the flag of the corresponding process step, detecting, by a second production system, whether the wafer carrier type of the new process matches the acceptable level of the corresponding process step or not and whether the new process matches the flag of the corresponding process step or not; and
if the second production system detects a mismatch, determining that the process data does not pass the detection and automatically popping up, on the present interface of the display, a prompt box containing second detection information in text form;
if detection of the second product system is passed, releasing, by the electronic device, the process data to a manufacturing execution system to manufacture a wafer;
wherein the level refers to a contamination level, and the flag refers to a contamination flag; the detection method further comprising:
when the new process is a new step, determining a process route to which the new step belongs according to the process data of the new process; obtaining contamination levels and contamination flags of a previous step and/or a next step of the new step in the process route; or
when the new process is a new route, determining a previous step and/or a next step of each step of the new route according to the process data of the new process; and obtaining a contamination level and a contamination flag of each step of the new route.
