Description
この場合には、例えば中間層15bと最下層15aの中間の比誘電率となるように密着層を構成することで、密着層は、中間層15bと最下層15aの中間の膜密度を有するように構成される。これにより、中間層15bと最下層15aとの膜密度の差が大きい場合であっても、その差が緩和され、密着性を高めることが可能となる。この密着層は、中間層15bと最上層15cとの間にも同様に設けることができる。
本実施例では、図1に示す実施形態で説明した半導体装置の拡散防止絶縁膜15における最上層15cの水分の透過防止効果について検証した。
本実施例では、実施形態で説明した半導体装置における拡散防止絶縁膜15のEM耐性について検証した。
