附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面 描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。
图 1是本发明实施例——种 TFT电性量测方法的流程示意图。
图 2是本发明实施例——种 TFT电性量测方法的原理示意图。
图 3是本发明实施例二一种 TFT电性量测装置的结构示意图。
图 4是按图 3中 A— A'向截面示意图。
具体实施方式
下面参考附图对本发明的优选实施例进行描述。
请参照图 1所示, 本发明实施例一提供一种 TFT电性量测方法, 包括: 步骤 S1 , 提供两个分别与源漏极金属相连的源漏极测试单元和一个与 栅极金属相连的栅极测试单元;
步骤 S2, 在栅极测试单元上施加第一电压, 在两源漏极测试单元两端 施加第二电压, 使与源漏极金属相接触的掺杂型非晶硅半导体导通; 以及 步骤 S3 , 量测两源漏极测试单元之间的电流。
其中, 源漏极测试单元和栅极测试单元均为金属薄片, 并且均通过测试 线(亦为金属线)分别与源漏极金属和栅极金属相连。
本实施例的 TFT电性量测方法的原理为:在栅极测试单元上施加第一电 压, 该第一电压为高电压, 大于其导通电压, 可使源极与漏极接通, 而对于 TFT器件, 其源极和漏极特性一样, 功能可以互换。 同时, 在两源漏极测试 单元两端施加第二电压, 使与源漏极金属相接触的掺杂型非晶硅半导体 n+ a-Si: H导通。 由于 n+ a-Si: H和测试线以及源漏极金属的电阻相对于源漏 极金属与 n+ a-Si: H之间的欧姆接触电阻可以忽略不计, 因此通过量测两源 漏极测试单元两端的电压及其之间的电流, 即可得出源漏极金属与 n+ a-Si: H之间的欧姆接触电阻。 而两源漏极测试单元两端的电压即所施加的第二电 压, 其为已知大小的预定值, 因此实际只需量测两源漏极测试单元之间的电 流即可。 具体请参照图 2所示, 假设施加在两源漏极测试单元两端的第二电 压为 VSD, 量测两源漏极测试单元之间的电流 ISD, 则源漏极金属与 n+ a-Si: H之间的欧姆接触电阻 R欧姆 =VSD/ISD。 另外, 图 2也示出了本发明实施例的 等效电路图, 其中 欧姆、 R2欧姆分别为漏极金属和源极金属与 n+ a-Si: H之 间的欧姆接触电阻, 如前所述, TFT器件的源极和漏极特性相同, 功能可互 4灸, @ jtb Rj欧姆 口 R2欧姆^ ^目同的, R欧姆 =^ 欧姆 +R2欧姆。
再请参照图 3和图 4所示,相应于本发明实施例一的 TFT电性量测方法, 本发明实施例二提供一种 TFT电性量测装置, 包括:
一个与栅极金属 11相连、 可被施加第一电压的栅极测试单元 1 ;
两个分别与源漏极金属 12相连、 两端可被施加第二电压的源漏极测试 单元 2;
所述第一电压和第二电压使与源漏极金属 12相接触的掺杂型非晶硅半 导体 15导通;
用于量测两源漏极测试单元 2之间的电流的量测单元。
图 4示出了本实施例所要量测的 TFT器件的一种典型结构示意图,其中, 栅极金属 11上覆盖有栅极绝缘层(具体为氮化硅层) 13 , 在栅极绝缘层 13 上依次形成非晶硅半导体层 (a-Si: H ) 14 和掺杂型非晶硅半导体层 (n+ a-Si:H ) 15 , 源漏极金属 12设置在掺杂型非晶硅半导体层 15上。
本实施例的 TFT电性量测装置, 提供栅极测试单元 1 , 通过金属线与栅 极金属 11相连;提供两个源漏极测试单元 2,通过金属线分别与源漏极金属 12相连。通过在栅极测试单元 1上施加第一电压,该第一电压大于其导通电 压, 使源极与漏极接通; 同时, 通过在两源漏极测试单元 2两端施加第二电 压, 使与源漏极金属 12相接触的掺杂型非晶硅半导体 15导通。 由于掺杂型 非晶硅半导体 15和测试线以及源漏极金属 12的电阻相对于源漏极金属 12 与掺杂型非晶硅半导体 15之间的欧姆接触电阻可以忽略不计, 因此通过量 测两源漏极测试单元 2两端的电压及其之间的电流,即可得出源漏极金属 12 与掺杂型非晶硅半导体 15之间的欧姆接触电阻。 而两源漏极测试单元 2两 端的电压即所施加的第二电压为已知大小的预定值, 因此实际只需量测两源 漏极测试单元 2之间的电流即可。具体的量测和计算请参照前述对图 2的描 述。
本实施例的 TFT电性量测装置可通过光罩上设计图形,按现有工艺即可 实现。 其中, 源漏极测试单元 2和栅极测试单元 1均为金属薄片, 测试线均 为金属线。
实施本发明实施例,一方面可以方便快捷地得出源漏极金属与掺杂型非 晶硅半导体之间的欧姆接触电阻, 另一方面通过所量测的电流变化, 可以了 解该欧姆接触电阻的变化, 以便于监控 TFT电性。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此依本发明权利要求所作的等同变化, 仍属本发明所涵盖的 范围。
