Quality Estimation of SEM Wafer Images
This paper describes a practical method for image quality estimation. In particular, this method applies to SEM images of VLSI wafers. Wafers are extremely sensitive to electron charging, since they may contain nonconducting materials. This forces utilization of low energy, low-current electron beams and short viewing times. The images generated under these SEM settings are noisy. An automatic ...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
A Hybrid Defect Detection Method for Wafer level Chip Scale Package Images
In the majority of semiconductor manufacturing, the visual inspection process of the wafer surface depends on human experts. However, the inefficiencies of human visual inspection has led to the development of image process to perform inspection tasks. The occurrence of different type of defect arises from the manufacturing processed variations, like miss-out calibration or poor maintenance of ...
متن کاملA New Method for Eye Detection in Color Images
The problem of eye detection in face images is very important for a large number of applications ranging from face recognition to gaze tracking. In this paper we propose a new algorithm for eyes detection. First, the face region is extracted from the image by skin-color information. Second, horizontal projection in image is used to approximate region of the eye be obtained . At last, the eye ce...
