IC芯片表面标识自动识别虚拟仪器系统的设计(New!) |
|
应用领域：
半导体、工业自动化
使用产品：
LabVIEW 7.0、IMAQ Vision、IMAQ Vision Assistant、PXI-1409、MBC-5051等
挑战：
构建IC芯片表面标识自动识别系统，实现对芯片表面英文字母、数字以及厂商图标的识别
应用方案：
使用NI公司LabVIEW、IMAQ Vision、IMAQ Vision Assistant等软件配合PXI-1409图像采集、MBC-5051 CCD黑白相机等图像采集硬件构建IC芯片表面标识自动识别系统，实现对英文字母、数字以及厂商图标的识别
介绍：
芯片表面标记自动识别技术是芯片制造技术不断高速发展的要求，其中芯片表面标识主要包括厂商图标、序列号（包括英文字母及数字）等。由于自动识别技术具有极其重要的意义，一直以来，人们都对该技术的研究投入了大量的人力物力，并取得了卓有成效的进展。它可以应用于芯片性能自动检测领域，提高芯片测试效率，进而提高厂商的生产能力，具有十分广阔的应用前景。
本系统使用NI的视觉系统开发工具构建，因而具有开发周期短、成本低等特点。系统综合运用了锐化、滤波、细化、特征识别等多种图像处理技术，成功地实现了从芯片自动跟踪定位、图像采集到图像预处理、骨架提取以及识别等一系列功能。
Abstract
With the incessant development of the chip manufacturing technology, developing the auto-recognizing system of the chip surface’s mark which mainly contains licenses and so on becomes more and more important. As this technique is of great importance, a lot of energy has been put into it and many achievements have been gained. This system can be used in the filed of the automation of the chip testing, so it can increase the throughput of the chip manufacturer.
Thanks to the using of the LabVIEW software and its IMAQ Vision image processing modules, the system’s exploit period is very short and its cost is especially cheap. With the comprehensive utilization of several kinds of technology, such as the threshold, filtering, arithmetic/logical operation, cutting, thinning, feature matching and so on, this system can bring all the expected functions to success in practical application.
