Description
p = p0 - ρu2/2 (1)
の関係がある。このようにガスの流速が増大すると、このガス流の周辺の静圧が減少するため、その周囲において他のガス導入管から導入された他の原料ガスあるいはサブフローガスが、静圧差により前記ガス流に引き寄せられ、その結果として、反応管内において、原料ガス及び/又はサブフローガスの渦流が生じる場合がある。したがって、原料ガス及び/又はサブフローガスのガス流が乱され、反応管内に設置された基板上に均一に供給されなくなり、膜厚が不均一となったり、組成が不均一となったりして膜作製上の再現性が著しく低下してしまう場合があった。
図1は、本実施形態における気相成長装置の概略構成を示す断面図であり、図2は、図1に示す気相成長装置の切替装置の概略構成を示す図である。
図5は、本実施形態における気相成長装置の概略構成を示す断面図である。
図5に示すように、本実施形態の気相成長装置30は、ガス導入部31A、及びこのガス導入部31Aと連続するようにして設けられたガス反応部31Bを含む、いわゆるパンケーキ型またはプラネタリー型の反応管31と、反応管31の、ガス反応部31Bの内部に表面32−nAが露出し、さらにパンケーキ型またはプラネタリー型の反応管31の中心軸I-Iに対して、同心状に配列されてなるサセプタ32−nとを具える。また、サセプタ32−n上には、それぞれ基板Snが載置されている。図示しないテーブルに32−nは保持され、図示しないヒータによりテーブル及びサセプタ32−nが加熱され、基板Snが所定の温度に保持される。自公転型の場合は、図示しないテーブルが公転し、サセプタ32−nが自転するが、自転や公転はしてもしなくてもよい。
