Description
2 薄膜結晶
3 ノズル
Claims (1)
- 結晶を気相成長法を用いて基台上に薄膜結晶を堆積して圧電薄膜を形成する圧電薄膜の形成方法であって、
前記基台上には、前記基台に向けて前記圧電薄膜の原料ガスを吐出するノズルが備えられており、
前記ノズルを、前記原料ガスを吐出させながら、前記基台から徐々に遠ざけるように前記基台に対して垂直方向に移動させることにより、前記圧電薄膜の中心になる部分に前記薄膜結晶を多く堆積させ、前記圧電薄膜の外周になる部分に従って前記薄膜結晶を少なく堆積させて、中心部分が厚く且つ外周部に従って薄い形状の前記圧電薄膜を成すことを特徴とする圧電薄膜の形成方法。
