  • 現今印刷電路板(Printed Circuit Board, PCB)產業蓬勃發展,生產逐漸精密化且線寬越來越小,為了提升印刷電路板製程的品質,必須要進行有效率的檢測。傳統是以人工目視辨別印刷電路板上的缺陷,不僅耗時且誤判率高,因此業界開始應用「自動光學檢測」(Automated Optical Inspection,AOI)設備來檢測產品缺陷,檢測出各類缺陷之後,若要將各類光阻圖案缺陷進行分類,需要提出另一種有效率的人工智慧模型,來針對數位微影所產生的光阻圖案缺陷進行分類與辨識,以達到產線最即時的回饋與修正。本文提出一種卷積神經網路(Convolution Neural Network, CNN)應用在影像的辨識與分類,針對六種最為常見的光阻圖案缺陷進行分類,並且在分類缺陷的任務中獲得將近90%的準確率,證明卷積神經網路是可以被應用在光阻圖案缺陷分類上。本文亦於台科大實驗室自行搭建的數位微影(Digital Lithography)曝光機台,採用數位微反射鏡裝置(Digital Micromirror Device , DMD),去進行實際曝光的光阻圖案特徵探討,包含二維以及三維兩種主要型態的光阻特徵,並整合二維及三維的自動化光學檢測,再根據其光阻輪廓的不同,定義為不同的光阻缺陷,透過本文所開發的缺陷分類模型進行缺陷分類,再根據數位微影缺陷修正程序,進行落點位置的修正,重新進行曝光實驗驗證修正結果,完成整套智慧化數位微影曝光與檢測程序的開發。


    The Printed Circuit Board (PCB) industry is developing well. Process is becoming more sophisticated and the line width is getting smaller and smaller. In order to improve the quality of the printed circuit board manufacturing process, efficient inspection must be carried out. Traditionally, artificial vision is used to identify defects on printed circuit boards. It is not only very time-consuming, but has a high rate of misjudgment. Therefore, the industry began to use Automated Optical Inspection (AOI) equipment to detect product defects. After detecting different defects, if we need to classify different photoresist pattern defects, it is necessary to propose another efficient artificial intelligence model to classify and identify different types of photoresist pattern defects, and then achieve the most immediate feedback and correction of the production line. This dissertation proposes a convolutional neural network (CNN) application in the identification and classification of images, and classify the six most common photoresist pattern defects. This model achieves nearly 90% accuracy in the task of classifying defects. It also proves that convolutional neural networks can be applied to the classification of photoresist pattern defects. This research also built a digital lithography machine in Laboratory of National Taiwan University of Science and Technology, and we adopt Digital Micromirror Device (DMD) to analyze the characteristics of the photoresist pattern of the actual exposure experiments. The results include two main types of photoresist features, two-dimensional and three-dimensional, and we integrate 2D and 3D automated optical inspection. They will be defined as different photoresist defects according to different profile. Next, the defect classification model developed in this research is used to classify different defects, and then according to the digital lithography defect correction procedure to correct exposure position of beam, and conduct exposure experiments to verify the correction results. This research completed the development of the entire intelligent digital lithography exposure and inspection procedure.
