Description
本技術の一実施の形態に係る第2の半導体装置の製造方法は、酸化物半導体材料を含む半導体膜を形成し、半導体膜に対向するゲート電極を形成し、ゲート電極と半導体膜との間に、ゲート電極から露出された側面を有するゲート絶縁膜を形成し、酸化物半導体材料を溶解可能な薬液を用いて、ゲート絶縁膜の側面を洗浄し、薬液は、モノエタノールアミンを含むものである。
1.実施の形態(ゲート絶縁膜の側面の洗浄工程を含むトランジスタの製造方法)
2.適用例1(表示装置および撮像装置の例)
3.適用例2(電子機器の例)
[構成]
図1は、薄膜トランジスタ(トランジスタ10)の要部の断面構成を模式的に表したものである。このトランジスタ10は、後述の本技術の一実施の形態に係る薄膜トランジスタの製造方法(後述の図2)を用いて製造されたものである。トランジスタ10は、例えば、トップゲート型の薄膜トランジスタであり、表示装置および撮像装置(後述の図8の表示装置2Aおよび図9の撮像装置2B)等の駆動素子に用いられる。このトランジスタ10が、本技術の半導体装置の一具体例に対応する。
図2は、トランジスタ10の製造方法の一例を工程順に表している。以下、このトランジスタ10の製造方法について説明する。
トランジスタ10では、ゲート電極15に閾値電圧以上のオン電圧が印加されると、半導体膜13のチャネル領域13aが活性化される。これにより、チャネル領域13aを間にした一対の低抵抗領域13b間に電流が流れる。
本実施の形態のトランジスタ10の製造方法では、薬液を用いてゲート絶縁膜14の側面14Sを洗浄するので、ゲート絶縁膜14の側面14Sの付着物Aが除去される。例えば、この付着物Aは、リーク成分100Lを含んでいる。洗浄は、半導体膜13を構成する酸化物半導体材料を溶解可能な薬液を用いて行うので、ゲート絶縁膜14の側面14Sからリーク成分100Lが除去される。
上記実施の形態において説明したトランジスタ10は、例えば表示装置(後述の図8の表示装置2A)および撮像装置(後述の図9の撮像装置2B)等の駆動回路に用いることができる。
上記表示装置2Aおよび撮像装置2B等は、様々なタイプの電子機器に用いることができる。図10に、電子機器3の機能ブロック構成を示す。電子機器3としては、例えばテレビジョン装置、パーソナルコンピュータ(PC)、スマートフォン、タブレット型PC、携帯電話機、デジタルスチルカメラおよびデジタルビデオカメラ等が挙げられる。
