【摘要】 随着全球半导体工业的发展,测试已经由过去作为单个集成电路制造企业生产中的一个工序渐渐分离成为半导体产业链中的独立一环,众多测试厂家之间存在激烈竞争,日益重视提高测试质量、效率以及综合收益和竞争力。由于传统的专有测试孤岛在生产中产生浪费和延误,而现实中测试设备供应商间的竞争又导致统一测试环境难以实现,因此,进行测试系统局部改进来提高兼容性和可靠性的研究,就具有了现实意义,这也是本论文的任务所在。本论文针对不同测试系统生成测试数据不统一,造成效率降低和成本无益浪费的情况,根据实际需要,进行文件转换来达到在数据的采集阶段进行格式统一的目的。STDF格式是一种简单、富有弹性、便于移植的数据格式,更重要的是它同时是自动测试设备领域以数字形式保存测量数据的最为普遍的应用格式,也是几乎可以应用于任何类型测试的通用的文件格式,因此选择它作为数据统一的标准;本论文的另一个特点是使用了perl语言进行转换工作,本语言具有强大的功能、简洁到极点的语法,尤其在不涉及到图形图像以及多媒体的情况下,是一种专门处理文本的语言工具;为了使转换程序更加具有实用性,我们还在Sun系统上建立日志文件,保证其自动运行和进行相关处理。论文首先对当前半导体行业的形势和测试领域面临的问题加以阐述,根据实际问题在第一章中进行了数据统一必然性的探讨与文件转换工具的选择;第二章从项目的格式特点入手,对二进制文件的特点加以分析和论述;第三、四章通过具体例子分析得到STDF和df文件的结构特点和组织形式;第五章进行软件转化设计和日志文件的生成;最后介绍作者在本课题中所做的工作和本系统的扩展性。更多还原

【Abstract】 With the development of global semiconductor industry, test, which was only asection of IC producing in the past, has being a separate procedure in thesemi-industry chain. More and more testing factories begin to enhance their quality,efficiency and pay attention to the awards and market competition. However, theisolated information point and the contest between different machine suppliers havemade it impossible to realize an uniform testing environment. Then, someimprovement in local, which is the aim of this project, is realizable and significative. According to the low efficiency and cost wasting resulted by different testingstandards, we convert the data format to given method during the course of datacollection. STDF, which is a simple, flexible and undergoing transplanting format, ischoised as the standard because of its catholicity and universality in the area of ATE.Perl language is used as the tool of converting files, which can bring up many merits,such as multi-functional, simple and professional to control text when the aim is notimages and vedio. The log built on Sun flat, will ensure batch controlling andreferring the related information. After introduce the situation and problems in semiconductor industry, the firstchapter affirms the inevitability of format converting and analyses the language tool.The second chapter expatiate the character of binary file then the third and forthchapters analyse and find the organization and unit structure of STDF and dlog file indetails. The fifth chapter converts the dlog file to STDF through Perl according to theorder of modules and produces the log file.更多还原
