Description
電気器具を小型化、軽量化しても性能が落ちないことはユーザーにとって当然の要求であり、電気器具には今以上の性能が要求され続ける。なお、電気器具の機能や性能を決定するのは、システムを構成するLSIの特性や、電気器具の表示部における表示装置の特性である。そこで、LSI等の半導体装置に関する微細化、高集積化や、表示装置の高輝度、高精細化に関する研究開発がさかんに進められている。微細度や集積度が向上することにより、ひとつのチップに搭載できる機能が多くなるため、上記したような電気器具の小型化、軽量化、高性能化の要求を満たす手段となり、表示装置においては、画素数が増えることで高精細な画像表示が可能となるからである。
さらに、同様に第3の層3上に第4の層4、第5の層5と積層するに従って、段差6の高低差が大きくなってしまっていた。
膜の選択された領域に凹みを形成することを指し、ある(絶縁)膜の深さ方向に膜厚分の深さをエッチングする場合、膜厚の深さ途中(膜厚より浅いところ)でエッチングをストップする場合のどちらも指すこととする。
次いで、開口部12においてアモルファスシリコン膜13上に所望の形状になるようにレジストからなるマスク14を形成し(図2(C))、エッチングして、半導体層15を形成する。半導体膜の結晶化処理は、エッチング処理前に行ってもエッチング処理後に行ってもどちらでもよい。また、結晶化方法は、公知の結晶化処理(レーザ結晶化法、熱結晶化法等)または触媒元素を添加して加熱処理を施す結晶化方法を用いてもよい。また、これらの結晶化方法を組み合わせて適用してもよい。ここまでの工程で、下地絶縁膜11bと半導体層15との高さが概略一致している。また、開口部を形成するためのエッチングに関しては本実施の形態ではウエットエッチングを想定しているが、もちろんドライエッチングでも問題無く行うことができる(図2(D))。
また、基板からの汚染物質の拡散を防ぐために、下地遮光膜102を形成する前に、絶縁膜を形成してもよい。
をゲッタリング領域108に移動させ、除去、あるいは濃度を低減するゲッタリングを行う。ゲッタリングを行う加熱処理としては、強光を照射する処理または加熱処理を行い、結晶質シリコン膜106に含まれるニッケルがほとんど存在しない、即ち膜中のニッケル濃度が1×1018/cm3以下、望ましくは1×1017/cm3以下になるように十分ゲッタリングする(図4(B))。
この処理により、半導体層の上部は酸化される。そして、酸化シリコン膜および半導体層の酸化した部分をエッチングして除去し、結晶性の向上した半導体膜を得ることができる。
として周期表の13族に属する元素、典型的にはボロン(B)またはガリウム(Ga)を導入する。
の小さなアクティブマトリクス基板を実現することを可能としている。
なお、下地絶縁膜501は、あるエッチャントに対してエッチングの選択比が大きくなるような積層構造とし、1層目501aをエッチングのストッパーの役割を果たす膜にすると第1の開口部502の形成の際に、開口部の深さ方向の制御がし易くなる。
なお、レーザ光照射により結晶化する場合には、照射処理前に半導体層503の含有水素量を5atomic%以下とすることが望ましいが、プラスチック基板を用いる場合、高温の加熱処理は不可能であるため、非晶質シリコン膜の成膜直後の段階で、水素濃度が低くなるような成膜条件を用いるとよい。
続いてゲート絶縁膜603に第2の開口部604を形成する(図8(C))。開口部の形成には、実施形態または実施例1で示したように公知のエッチング法を用いればよい。
)。
ここで示す駆動回路部650のnチャネル型TFT652、pチャネル型TFT653、及び画素部651のスイッチング用TFT654、電流制御用TFT655は、本発明を用いて、実施例2と同様にして作製されるものである。なお、本実施例では、ゲート電極の導電層を2層積層して形成している。
に示すように少なくとも一部が開口部801からはみ出るように形成する。
)。
しかし、層間絶縁膜の膜厚を厚くすることにより、例えば、導通をとるためのコンタクトホールの形成に時間がかかってしまう。また、形成されたコンタクトホールは、アスペクト比が大きいため、配線を形成する際によく用いられるスパッタ成膜等では、カバレッジが悪く、コンタクトホール上部でひさしが形成されてしまい、コンタクトホール底面まで配線が形成されずに断線が起こってしまうという問題もある。
これらの電気器具の表示部に用いられる表示装置は、平面型の表示装置の一例である。表示装置が駆動回路一体型の場合、画素部と駆動回路との集積度が異なるが、本発明を適用すると、CMP法による研磨処理やSOG膜成膜による平坦化を行わなくても、その表面を平坦化することができる。
さらに、音声出力部3005、操作キー3006、電源スイッチ3007、音声入力部3008を有している。本発明は、携帯電話の表示部に用いられるプラスチック基板上に形成される半導体装置にも適用することができ、CMP法による研磨処理やSOG膜成膜による平坦化処理を行わなくても平坦化することができる。
なお、図17では、実施例2、及び実地例5のTFT作製工程を用いて本実施例を説明しているが、これに限定されることはなく実施形態や実施例1〜4のいずれを適用することも可能である。なお、図17のTFT作製方法は実施例2に従えばよいので説明は省略する。
の906に相当する段差を除去してコンタクトホールを開口すれば、コンタクトホールの底面を下部配線の頭が凸状に露出した形状にすることができる。この配線の下となる絶縁膜は、開口部内に島状に残して形成しても、隣接した二つの開口部を形成してもよい。
