Abstract
【解決手段】不活性ガスイオン又はハロゲンイオン又はH3 +イオンから選ばれた一のイオンを照射することにより形成された脆化層を劈開面として半導体基板をベース基板から分離することで、所望の厚さのシリコン層を有するSOI基板を得ることができる。また、絶縁表面を有する基板若しくは絶縁基板に、単結晶半導体層を接合するに際し、接合を形成する面の一方若しくは双方に、好ましくは有機シランを原材料として成膜した酸化シリコン膜を用いることで、ガラス基板等の耐熱温度が700℃以下の基板であっても接合部の接着力が強固な単結晶半導体層を有する半導体基板を得ることができる
【選択図】図3
Description
本発明に係る半導体基板を図1(A)(B)に示す。図1(A)においてベース基板100は絶縁表面を有する基板若しくは絶縁基板であり、アルミノシリケートガラス、アルミノホウケイ酸ガラス、バリウムホウケイ酸ガラスのような電子工業用に使われる各種ガラス基板を適用される。その他に石英ガラス、シリコンウエハーのような半導体基板も適用可能である。単結晶半導体層102は単結晶半導体であり、代表的には単結晶シリコンが適用される。その他に、水素イオン注入剥離法のようにして単結晶半導体基板若しくは多結晶半導体基板から分離可能であるシリコン、ゲルマニウム、その他、ガリウムヒ素、インジウムリンなどの化合物半導体による結晶性半導体層を適用することもできる。
本実施の形態では、実施の形態1で示した半導体基板の製造方法について図3(A)乃至(C)と図4を参照して説明する。
本実施の形態では、実施の形態2で示した半導体基板の製造方法の別の形態について説明する。
本実施の形態では、実施の形態2又は実施の形態3で示した半導体基板の製造方法の別の形態について説明する。
本実施の形態では、実施の形態1及び実施の形態2で示した半導体基板を用いた半導体装置について図6乃至図11を参照して説明する。
半導体基板は、ベース基板100に接合層104を介して単結晶半導体層102が設けられている。単結晶半導体層102の膜厚は5nm乃至500nm、好ましくは10nm乃至200nmである。単結晶半導体層102の厚さは、図3で説明した脆化層103の深さを制御することにより適宜設定できる。単結晶半導体層102にはしきい値電圧を制御するために、硼素、アルミニウム、ガリウムなどのp型不純物を添加する。例えば、p型不純物として硼素を5×1017cm−3以上1×1018cm−3以下の濃度で添加されていても良い。ベース基板100にはバリア層105として窒化シリコン層と酸化シリコン層が積層形成されている。ベース基板100にバリア層を設けることで、単結晶半導体層102の汚染を防ぐことができる。なお、窒化シリコン層に換えて、窒化酸化シリコン層、窒化アルミニウム層、窒化酸化アルミニウム層を適用しても良い。
