Description
先ず、単結晶シリコンウエハ上に熱酸化膜を形成し、このシリコンウエハ(基板4004)を図6の装置の成膜室4009内の基板ホルダー4003にセットした。次いで、排気ポンプ4007により成膜室4009内を8×10−6Paまで排気した。その後、Arガスをガス導入口4010から成膜室4009に導入し、成膜室4009内の条件を以下のものとした。
基板温度:150℃
成膜室内ガス雰囲気温度:150℃
成膜室内混合ガス圧力:0.6Pa
次いで、Irターゲット、Siターゲットを用いて、スパッタリング法により、シリコンウエハの熱酸化膜上に100nmの膜厚でIr100−XSiX膜を形成し、試料1〜4を得た。
得られた上記試料1〜4についてRBS(ラザフォード後方散乱)分析を行い、各試料の組成分析を行った。その結果を表1に示す。
本実施例の上部保護層が形成された試料番号1〜4と、流路形成部材の一部となる有機密着向上膜(ポリエーテルアミド樹脂)307との密着性を簡易的に評価するために、テープ引き剥がし試験をPCT(Pressure Cooker Test)後に行った。
本実施例の試料番号1〜4とインク(BCI−7eC:キヤノン製)との電気化学反応による溶出を評価するため、図10に示すように対向する電極を設ける。そして、一部マスクを施した本実施例の試料を陽極側に配置し、電源によって24Vを印加することで、陽極側で起こる反応について、膜厚が減少した場合は、エッチング、逆に膜厚が増加した場合は陽極酸化が起こっているものと評価した。その結果を表3に示す。
上部保護層107として、例えば、インクとの接触面や樹脂層密着部の組成がIr82.6Si17.4の組成比の膜を用いた場合を示す。
