Description
2.金属ホットプレートに直接基板を置いて透明導電膜を成長させるため、ホットプレートの熱分布が直接透明導電膜の分布に繋がり、ホットプレートの熱分布が不均一の場合には、透明導電膜のシート抵抗等が不均一になるという問題があった。
3.チャンバーが1つのため、基板の処理速度が遅く、製膜速度が遅いという問題があった。
主反応は、以下の1、2のとおりであり、
1.Zn(C2 H5 )2 +2H2 O→Zn(OH)2 +2C2 H6
2.Zn(OH)2 →ZnO+H2 O
ジボラン(B2 H6 )がわずかにZnO中に取り込まれる。
詳細には、
Zn(C2 H5 )2 +H2 O+nB2 H6 →ZnO:B+2C2 H6 +nB2 O3 で、nはごくわずかである。
従来のノズル(図6参照。)を使用してバッチ式で繰り返し製膜を行った場合と、本発明のノズル(図2参照。)を使用して連続的に製膜を行った場合の透明導電膜のシート抵抗を比較すると、図4に示すように、従来のノズルを使用した場合、製膜回数が増加するにつれて、ノズルが加熱され、基板上への原料供給が減少することで膜厚が薄くなるため、透明導電膜のシート抵抗が増加し、太陽電池の変換効率が低下するという問題点があったが、本発明のノズルを使用して連続的に製膜を行った場合には、ノズルの冷却機構によって透明導電膜のシート抵抗は一定を示すことが証明された。
