Description
第1に、成膜用台の配置数を制御することにより電子放出点(発光サイト)の数を任意に制御することができること、
第2に、成膜用台の配置間隔の大きさを制御することにより発光サイトの密度を任意に制御することができること、
第3に、成膜用台の配置位置を制御することにより発光サイトの位置を任意の位置に設定することができることである。
第4として、上記(1)で説明したように、配置環境の圧力を中高真空に設定しても優れた電界放射特性を安定して発揮することができる電子エミッタを安価に製造することができること、である。
図7(a)で示す基板12上に図7(b)で示すようにフォトレジスト22を塗布する。次いで図7(c)で示すようにフォトマスクのパターンを露光によりフォトレジスト22に転写し、次いで、図7(d)で示すように現像によりパターン以外のフォトレジスト22を除去し、図7(e)で示すようにエッチングし、最後にフォトレジスト22を除去することにより、図7(f)で示すように基板12に一体化された成膜用台14を形成する。以上のフォトリソグラフィー技術により基板12に成膜用台14を成形した後、次の炭素膜の製造工程に移行する。
この炭素膜の成膜には図9で示す直流プラズマCVD装置を用いる。この直流プラズマCVD装置24は、真空チャンバ26と、この真空チャンバ26の内部に平行に対向配置した一対の第1、第2平板電極28,30とを備える。真空チャンバ26はガス導入口26aとガス排気口26bとを備える。直流電源32の負極側を上側の第1平板電極28に接続し、直流電源32の正極側を接地する。下側の第2平板電極30を接地する。
