Description
始めに、本発明の実施形態による成膜方法を実施するのに好適な成膜装置について説明する。
図1から図3までを参照すると、本発明の実施形態による成膜装置は、ほぼ円形の平面形状を有する扁平な真空容器1と、この真空容器1内に設けられ、真空容器1の中心に回転中心を有する回転テーブル2と、を備えている。真空容器1は、有底の円筒形状を有する容器本体12と、容器本体12の上面に対して、例えばOリングなどのシール部材13(図1)を介して気密に着脱可能に配置される天板11とを有している。
次に、これまでに参照した図面に加えて図6を参照しながら、本発明の実施形態による成膜方法について、上述の成膜装置を用いて実施される場合を例にとり説明する。
まず、図示しないゲートバルブを開き、搬送アーム10により搬送口15(図3)を介してウエハWを回転テーブル2の凹部24内に受け渡す。この受け渡しは、凹部24が搬送口15に臨む位置に停止したときに凹部24の底面の貫通孔を介して真空容器1の底部側から不図示の昇降ピンが昇降することにより行われる。このようなウエハWの受け渡しを回転テーブル2を間欠的に回転させて行い、回転テーブル2の5つの凹部24内に夫々ウエハWを載置する。
・ウエハWの温度: 300℃
・TEMAZの供給量: 0.4cc/min(液体として)
・オゾン供給量: 300 g/Nm3(酸素ガスの供給量は10slm)
・分離ガスの供給量(分離ガスノズル41、42の各々からの供給量):10slm。
なお、比較例として、TEMAZの供給を停止することなく、TEMAZとオゾンガスとを同時に供給してZrO膜を成膜した(供給時間10秒に相当)。
(1)トリメチルアルミニウム(TMA)及びオゾンガスの組み合わせによる酸化アルミニウム膜の成膜、
(2)テトラキスエチルメチルアミノハフニウム(TEMAH)及びオゾンガスの組み合わせによる酸化ハフニウム膜の成膜、
(3)ストロンチウムビステトラメチルヘプタンジオナト(Sr(THD)2)及びオゾンガスの組み合わせによる酸化ストロンチウム膜の成膜、
(4)チタニウムメチルペンタンジオナトビステトラメチルヘプタンジオナト(Ti(MPD)(THD))及びオゾンガスの組み合わせによる酸化チタニウム膜の成膜、
(5)ビスターシャルブチルアミノシラン(BTBAS)及びオゾンガスの組み合わせによる酸化シリコン膜の成膜、及び
(6)有機アミノシランガス及びオゾンガスの組み合わせによる酸化シリコン膜の成膜などにも適用可能である。
