Description
絶縁基板と、前記絶縁基板の上方に位置するシリコン製の第1半導体層と、前記第1半導体層よりも上方に位置する金属酸化物製の第2半導体層と、前記第1半導体層と前記第2半導体層との間に位置するシリコン窒化物製の第1絶縁膜と、前記第1絶縁膜と前記第2半導体層との間に位置しているシリコン酸化物製の第2絶縁膜と、前記第1絶縁膜と前記第2半導体層との間に位置し、前記第1絶縁膜および前記第2絶縁膜よりも水素の拡散性が低いブロック層と、を備え、前記第2絶縁膜は前記ブロック層の下面に接し、前記第2半導体層は、前記ブロック層の上面に接し、前記ブロック層は、酸化アルミニウム製である、半導体装置が提供される。
なお、本実施形態の説明において、上(または上方)とは、方向Zの矢印の向きに相当し、下(または下方)とは、方向Zの矢印とは逆の向きに相当するものとする。
半導体装置1は、絶縁基板10、アンダーコート層UC、半導体層SC1、絶縁膜11、ゲート電極ML1,ゲート電極ML2、絶縁膜12、絶縁膜13、ブロック層HB、半導体層SC2、絶縁膜14、絶縁膜15、等を備えている。
ブロック層HBの厚さは、均一であっても良く、不均一であっても良い。図示した例では、ブロック層HBは、後述する電極ML3a,ML3bの外縁部に対向する位置において上面HBbに段差を有しており、半導体層SC2に対向する領域の厚さが半導体層SC1に対向する領域の厚さより厚い。ブロック層HBは、ゲート電極ML1や半導体層SC1等の導電性部材との間での不要な容量の形成を抑制する観点や、ブロック層HBの上面HBbと半導体層SC2の下面SC2aとが接している場合のチャネル層の短絡を防止する観点から、絶縁性の材料で形成されていることが望ましい。ブロック層HBを形成する材料としては、例えば、金属酸化物であるAlOx、TiOx、ZrOx、TaOx、HfOx等や、SiF4を原材料の一つとして形成された水素含有量の少ないSiNx、SiON等が挙げられる。水素の遮断性能や光透過性の観点からブロック層HBは、酸化アルミニウム(AlOx)製であることが望ましい。
絶縁膜15は、絶縁膜14の上に位置する。絶縁膜15は、一例ではシリコン窒化物製である。なお、絶縁膜15は、上方からの水分の侵入を抑制する観点から、高い水蒸気バリア性を有することが望ましい。
半導体装置1は、更にゲート電極ML1およびML2を備えている。ゲート電極ML1およびML2は、同一層(絶縁膜11)上に位置しており、同じ材料で形成されているので、同じ工程内で一括に形成することができる。すなわち、半導体装置1は、製造工程数を削減し、製造コストを抑制することができる。
本変形例は、ブロック層HBの形状が島状にパターニングされている点で、図1に図示した構成例と相違している。
本変形例は、ブロック層HBと半導体層SC2との間に絶縁膜13が位置している点で、図1に図示した構成例と相違している。図示した例では、ブロック層HBは絶縁膜12の上に位置し、絶縁膜13はブロック層HBの上に位置し、半導体層SC2は絶縁膜13の上に位置している。すなわち、絶縁膜13は、ブロック層HBの上面HBbおよび半導体層SC2の下面SC2aにそれぞれ接している。
本変形例においては、絶縁膜12から絶縁膜13への水素の拡散を抑制することができる。すなわち、水素の拡散をより水素供給源に近い位置で抑制することができる。
本変形例は、ブロック層HBの形状が島状にパターニングされている点で、図3に図示した変形例と相違している。本変形例によれば、図2を用いて説明した変形例と同様の効果を得ることができる。
本変形例は、半導体層SC2に対向配置されたゲート電極ML4を備えている点で、図1に図示した構成例と相違している。
本変形例によれば、半導体装置1は、光リーク電流による薄膜トランジスタTR2の性能低下を抑制することができる。
