Abstract
一种薄膜晶体管的制备方法包括：在衬底基板上形成图形化的有源层(12)，在有源层和衬底基板上依次形成整层栅极绝缘层和整层栅极层(13、14)；在整层栅极层上形成图形化的光刻胶层(15)；以光刻胶层为掩膜，图形化整层栅极层以及整层栅极绝缘层(16)；以减薄后的光刻胶层为掩膜，图形化准栅极(18)；去除减薄后的光刻胶层(19)；采用PECVD工艺在衬底基板、有源层、栅极绝缘层以及栅极上形成第一绝缘层；同时，以栅极绝缘层以及栅极为掩膜介质，利用PECVD工艺中前驱气体的等离子体对有源层进行高导处理(20)；形成源极和漏极(21)。降低了薄膜晶体管的阈值电压的调节难度，实现了阈值电压便于调节的薄膜晶体管的高精度制备。
