Description
次に、本発明を用いた実施例を、図2〜図3を用いて示す。図2に示すように、トランジスタ等の駆動素子(不図示)が設けられたSiの基板1上に、SiO2にボロンとリンを添加した層間膜2が厚さ500nmで形成されている。層間膜2の上には、他の配線4としてAl−Siの合金を厚さ400nm形成されている。他の配線4の上には、SiO2からなる絶縁層5が厚さ1μm形成されている。絶縁層5は、発熱部12の熱を蓄熱する蓄熱層としての機能も有している。さらに絶縁層5の上には、TaSiNからなる発熱部12が厚さ50nmで形成されている。発熱部12の両端は、配線10と接している。配線10は、絶縁層5に設けられたコンタクトホールを介して、他の配線4と接している。
本発明を用いた実施例2を、図7に示す。部材11の形状以外の構成及び製造方法については実施例1と同じであるため、省略する。実施例1で示したように、図1のように部材11を設けることで熱干渉を防止できるが、更に高速化するような場合には、発熱部12の体積を大きくすることで調整することが出来る。しかしながら、部材11と発熱部12の距離は、近すぎると絶縁層5が蓄熱層としての効果を発揮できず、インクが膜沸騰する前に発熱部12の熱が部材11へ逃げてしまうため最低でも1um離した位置に配置する必要がある。このような場合、図7(a)及び図7(b)に示すように、発熱部12の中央を結んだ直線上の部材11の幅よりも、発熱部12の中央を結んだ直線上から離れた部材11の幅を広くし、部材11の体積を多くすることが好ましい。このように部材11を設けることで蓄熱に必要な距離を確保しつつ、より効率的に発熱部12で発生する余剰の熱を放熱することができる。
本発明を用いた実施例3を、図8に示す。部材11の形状以外の構成及び製造方法については実施例1と同じであるため、省略する。
