耐高压测试座
[0001]本技术涉及半导体产品测试
,具体涉及耐高压测试座。
技术介绍
[0002]传统的测试座设计是由吸嘴直接将材料压到测试片的上方进行测试的,这种测试方式是暴露在空气的环境中的,测试电压在2kV以下时是没有问题的,当测试2kV以上高电压的情况时,由于空气中含有导电介质,容易成被测产品漏电大测试不准确,严重的甚至打火造成测试片或者材料引脚的烧毁。例如2021年10月08日公布的一篇申请号为CN2021109949360的一种基于转盘式测试机自动测试晶圆的方法的技术专利。其中,转盘式测试机包括工控机、电控转盘、扫描目镜和多个测试站,电控转盘上设置有上料工位、取料工位和多个测试工位,且上料工位、取料工位和多个测试工位呈环形均匀布置;每个测试站具有探针,多个测试站的探针分别设置在多个测试工位的上方;扫描目镜设置在上料工位的正上方,工控机分别与电控转盘、扫描目镜和测试站连接。基于该转盘式测试机能够同时对放置在转盘上的多个晶圆进行测试。该方法中采用的测试机同样存在被测产品漏电大测试不准确,严重的甚至打火造成测试片或者材料引脚的烧毁等问题。
