Wafer Bonding Inspection Module for Adhesive Surface Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semiconductor processing systems lack a convenient and effective inspection mechanism to detect defects on contact surfaces and adhesive coating layers during the temporary bonding process, leading to potential flaws in the subsequent TSV process.
Innovation Solution
A semiconductor processing system equipped with an outer frame, image capturing modules, a driving mechanism, and an inspection module that captures and analyzes images of workpieces to identify defects, ensuring only defect-free workpieces are processed further.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no inspection mechanism is provided in the temporary bonding process, then the process can proceed without interruption, but defects such as damage, dirt, or uneven color on the contact surfaces or adhesive coating layer will remain undetected and cause flaws in the finished product
Solution Approach 1:
The inspection module performs defect detection on contact surfaces and adhesive coating layers before the temporary bonding process completes. By conducting inspection in advance, the system identifies defects early, allowing for timely intervention before flawed products are formed, thus improving reliability without requiring complex post-processing inspection systems
Solution Approach 2:
The inspection module acts as an intermediary component between the bonding process and the finished product. It introduces an intermediate inspection stage that detects defects without disrupting the overall bonding process flow, resolving the contradiction by adding a moderate-level inspection capability rather than a fully complex inspection system
2Reliability
If an inspection mechanism is introduced to detect defects on contact surfaces and adhesive coating layers, then product quality improves, but the device complexity and process time increase
Solution Approach 1:
The inspection module is integrated into the existing temporary bonding equipment, merging the inspection function with the bonding process. This combination allows defect detection to occur during the bonding process itself rather than as a separate sequential step, improving defect detection capability while minimizing additional process time
Solution Approach 2:
The inspection process operates continuously during the bonding process without interrupting the workflow. The system maintains continuous monitoring of contact surfaces and adhesive layers, ensuring defect detection capability is sustained throughout the process without causing time loss through repeated stoppages

AI summary
A semiconductor processing system includes an outer frame, a wafer processing equipment, an image capturing module, a tray, a driving mechanism and an inspection module. The wafer processing equipment is disposed within the outer frame. The image capturing module is disposed on one side of the wafer processing equipment, and having an image-capturing coverage. The tray loads a workpiece. The driving mechanism is movably disposed on the outer frame, fixedly connected to the tray for linearly moving the tray. The inspection module is electrically connected to the driving mechanism and the image capturing module. When the driving mechanism moves the tray loading the workpiece into the image-capturing coverage, the image capturing module captures an inspected image of the workpiece within the image-capturing coverage, and the inspection module performs a defect identification procedure for the workpiece shown in the inspected image.
