Description
本発明者は、チャネル領域における不純物濃度の理想的なステッププロファイルを容易且つ確実に実現すべく鋭意検討し、以下のように本発明に想到した。
以下、上記した基本骨子を踏まえ、本発明をCMOSトランジスタに適用した具体的な実施形態について、図面を参照しながら詳細に説明する。本実施形態では、説明の便宜上、CMOSトランジスタの構成をその製造方法と共に説明する。
図1〜図4は、本実施形態によるCMOSトランジスタの製造方法を工程順に示す概略断面図である。
次に、活性領域3側のみを覆うレジストマスク(不図示)を形成し、N型ウェルを形成すべく活性領域2にN型不純物、ここではリン(P)を例えば加速エネルギーが400keV、ドーズ量が2×1013/cm2及び加速エネルギーが150keV、ドーズ量が3×1012/cm2の条件でイオン注入する。Pの代わりに砒素(As)をイオン注入するようにしても良い。
そして、選択エピタキシャル成長法により、下部チャネル層6,8上それぞれノンドープ状態の半導体膜、ここではシリコン膜を10nm程度の膜厚に成長させ、上部チャネル層9を形成する。
詳細には、比較的重い元素、ここではGeを用いて上部チャネル層9から基板内部へ注入し、上部チャネル層9から下部チャネル層6,8を含むシリコン基板1内の所定深さ(破線Dで示す)まで、非晶質化(アモルファス化)する。ここで、所定深さDとしては、後述するソース領域17,22及びドレイン領域18,23のシリコン基板1との接合界面よりも深い位置とすることを要する。なお、Geの代わりに、SiやArを注入するようにしても良い。
詳細には、活性領域3側のみを覆うレジストマスク31を形成し、活性領域2にP型不純物、ここではホウ素(B)を例えば加速エネルギーが0.5keV、ドーズ量が1×1015/cm2の条件でイオン注入する。このとき活性領域2では、キャップ絶縁膜20及びゲート電極12がマスクとなり、ゲート電極12の両側にP型のエクステンション領域15が形成される。また、イオン注入領域は先にアモルファス化されているため、チャネリングによる接合深さの増加を防ぐことができる。
詳細には、活性領域3側を覆うレジストマスク31を灰化処理等により除去した後、活性領域2側のみを覆うレジストマスク32を形成する。そして、このレジストマスク32を用い、活性領域3にN型不純物、ここでは砒素(As)を例えば加速エネルギーが5keV、ドーズ量が1.5×1015/cm2の条件でイオン注入する。このとき活性領域3では、キャップ絶縁膜20及びゲート電極14がマスクとなり、ゲート電極14の両側にN型のエクステンション領域19が形成される。また、イオン注入領域は先にアモルファス化されているため、チャネリングによる接合深さの増加を防ぐことができる。
詳細には、活性領域2側を覆うレジストマスク32を灰化処理等により除去した後、ゲート電極12及び14を覆うように全面に絶縁膜、ここではシリコン酸化膜(不図示)を堆積する。そして、このシリコン酸化膜の全面を異方性エッチング(エッチバック)し、活性領域2ではキャップ絶縁膜20及びゲート電極12の両側面のみにシリコン酸化膜を、活性領域3ではキャップ絶縁膜20及びゲート電極14の両側面のみにシリコン酸化膜をそれぞれ残し、サイドウォールスペーサ16,21を形成する。
詳細には、活性領域3側のみを覆うレジストマスク33を形成し、活性領域2にP型不純物、ここではホウ素(B)を例えば加速エネルギーが5keV、ドーズ量が4×1015/cm2の条件でイオン注入する。このとき活性領域2では、キャップ絶縁膜20、ゲート電極12及びサイドウォールスペーサ16がマスクとなり、サイドウォールスペーサ16の両側にP型のエクステンション領域15と一部重畳するように、エクステンション領域15よりも深いP型のソース領域17及びドレイン領域18が形成される。ここで、アモルファス化された所定深さDは、ソース領域17及びドレイン領域18のシリコン基板1との接合界面よりも深いため、エクステンション領域15、ソース領域17及びドレイン領域18はアモルファス化された部位に形成される。
詳細には、活性領域3側を覆うレジストマスク33を灰化処理等により除去し、活性領域2側のみを覆うレジストマスク34を形成し、活性領域3にN型不純物、ここではリン(P)を例えば加速エネルギーが20keV、ドーズ量が5×1015/cm2の条件でイオン注入する。このとき活性領域3では、キャップ絶縁膜20、ゲート電極14及びサイドウォールスペーサ21がマスクとなり、サイドウォールスペーサ21の両側にN型のエクステンション領域19と一部重畳するように、エクステンション領域19よりも深いN型のソース領域22及びドレイン領域23が形成される。ここで、アモルファス化された所定深さDは、ソース領域22及びドレイン領域23のシリコン基板1との接合界面よりも深いため、エクステンション領域19、ソース領域22及びドレイン領域23はアモルファス化された部位に形成される。
詳細には、先ず、活性領域2側を覆うレジストマスク34を灰化処理等により除去する。
そして、処理温度を450℃〜650℃の範囲内、ここでは600℃とし、30分間の低温固相エピタキシャル成長法により、上記のアモルファス化の後に導入した各種不純物、即ち活性領域2側ではエクステンション領域15、ソース領域17及びドレイン領域18のP型不純物、活性領域3側ではエクステンション領域19、ソース領域22及びドレイン領域23のN型不純物を活性化すると共に、アモルファス部分、即ちシリコン基板1の所定深さDから上方の部分(下部チャネル層6,8を含む)及び上部チャネル層9を再結晶化する。ここで、所定深さDの位置において、アモルファス部分が再結晶化された際の履歴として、残留欠陥面(破線Rで示す)が残る。
詳細には、活性領域2,3上を含む全面に、スパッタ法等により金属、例えばCoまたはNiを堆積し、650℃以下の低温、ここでは400℃で30秒間の熱処理を施すことにより、堆積した金属とソース領域17,22及びドレイン18,23のシリコンとを反応させ、シリサイド層24を形成する。その後、未反応の金属をウェットエッチングにより除去し、更に650℃以下の低温、ここでは500℃で30秒間の熱処理を施し、最終的なシリサイド層を形成する。ここで、ゲート電極12,14上にはそれぞれキャップ絶縁膜20が形成されているため、ウェットエッチング時のゲート電極12,14のエッチングを防止することができる。
