The main scope for the study is focusing on the resolution of leakage issue during electrical test on the MEMS display. The laser repair technology is capable to diagnose and find the failure circuits after first electrical test and performing repair. This process flow is able to turn the failed panel to a pass panel. MEMS Display is a new generation technology product, so there is neither document nor experience for repair process on the MEMS display. This study is going to analysis defect model on the MEMS display and find out the most suitable repair process. This study is not only optimize the best laser repair parameters but also improve the life time for the laser repair system .
The process for MEMS Display is different from TFT LCD. Need to setup an optimized repair specification for the MEMS Display Laser Repair. To do so could help engineer easily and accurate determine the laser repair mode. Specify 4 laser repair mode.
1. Surround Repair
2. L Type Laser Repair
3. L Type Segmentation Repair
4. Large Area Repair
To verify the repair result by comparing the result between 1st and 2nd electrical measurement.
