Description
LixSiyMzOvNw (化学式1)
ただし、式中、0.3≦x≦0.46、0.05≦y≦0.15、0.016≦z<0.05、0.42≦v<0.50、0≦w≦0.029であり、MはNb、Ta、P及びWよりなる群から選択された一つ以上を示す。
ただし、式中、0.3≦x≦0.46、0.05≦y≦0.15、0.016≦z<0.05、0.42≦v<0.5、0≦w≦0.029であり、MはNb、Ta、P及びWよりなる群から選択された一つ以上を示す。
シリコン基板上に2インチ直径のLi2O、SiO2、Nb2O5ターゲットをそれぞれ利用して4000Å厚さの固体電解質薄膜を製造した。
実施例1で示されるようにLi2O−SiO2−Nb2O5より構成された固体電解質薄膜は最大イオン伝導度が5X10−7S/cmほどを示した。前記固体電解質のイオン伝導度向上のために、実施例1と同じ工程条件で同時スパッタリング時の反応ガスのうち一部あるいは全部を窒素に置換した。この時、反応ガスの総流量は20sccmとし、窒素の流量を2〜20sccmとした。
実施例2から分かるように、酸化物系の固体電解質に少量の窒素が流入することによりイオン伝導度が大きく高まることが分かった。実施例2のNb2O5の代わりにLi3PO4を使用して固体電解質薄膜を製造し、この時の組成によるイオン伝導度の変化を表4に示す。
