Abstract
【解決手段】ガラス基板等の支持基板に、単結晶半導体層を接合するに際し、支持基板または単結晶半導体基板の一方若しくは双方に、酸化シリコン膜を用いる。本構成によれば、ガラス基板等の耐熱温度が700℃以下の基板でであっても接合部の接着力が強固なSOI層を得ることができる。また、単結晶半導体層が分離された単結晶半導体基板は、半導体層が分離された面側から単結晶半導体基板にレーザ光を照射して、単結晶半導体基板の表面を溶融させ、一領域あたりの溶融時間を0.5マイクロ秒乃至1ミリ秒とする再生処理を施した後、再利用する。

Description
本発明は、単結晶半導体基板から薄膜の単結晶半導体層を剥離(分離)した後の、単結晶半導体基板の平坦化プロセスに関するものである。図1に、本発明による半導体基板の作製工程を説明するフロー図の一例を示す。
0.8d≦δ≦1.5d(但し、δ=λ/4πk)・・(1)
を満たす範囲の波長のことをいう。
図1乃至図4を用いて説明した半導体基板の作製方法では、ガラス基板等の耐熱温度が700℃以下の支持基板であっても、単結晶半導体基板との結合力を強固にすることができる。また、無アルカリガラス基板などの各種のガラス基板を支持基板に適用することが可能となる。従って、支持基板にガラス基板を用いることで、一辺が1メートルを超える大面積な半導体基板を製造することができる。このような大面積な半導体製造基板に複数の半導体素子を形成することで、液晶ディスプレイ、エレクトロルミネッセンスディスプレイを作製することができる。また、このような表示装置だけでなく、半導体基板を用いて、太陽電池、フォトIC、半導体記憶装置など各種の半導体装置を製造することができる。
