Description
図1は本実施の形態1の高耐圧pMISQHp1の一例の要部平面図、図2は図1と同一箇所の平面図であって特に高耐圧pMISQHp1の電界緩和機能を持つp-型の半導体領域PV1とn+型の半導体領域NVkとの配置関係を示した要部平面図、図3は図1と同一箇所の平面図であって特に高耐圧pMISQHp1のゲート電極HGと活性領域Lとn+型の半導体領域NVkとの配置関係を示した要部平面図、図4は図1と同一箇所の平面図であって特に分離領域および活性領域Lを示した要部平面図、図5は図1〜図4のX1−X1線の断面図、図6は図1〜図4のX2−X2線の断面図、図7は図1〜図4のY1−Y1線の断面図をそれぞれ示している。なお、ここでは、高耐圧pMISに本発明を適用した場合について説明するが、p、nの導電型を逆にすることで、高耐圧nMISに適用することもできる。また、図4は平面図であるが図面を見易くするため分離領域にハッチングを付す。また、第1方向Xは、各図の左右横方向であってゲート長方向(チャネル長方向)またはゲート電極HGの短方向を示し、第2方向Yは、上記第1方向Xに直交する方向であり各図の上下縦方向であってゲート幅方向またはゲート電極HGの長手方向を示している。
前記実施の形態1では、ソースおよびドレインの両方ともがウエルとの間で耐圧を確保できる構成について説明したが、本実施の形態2では、ソース−ウエル間に大きな耐圧を必要としない場合の高耐圧MIS構造の一例を説明する。すなわち、nMISの場合、p型ウェルが共通のGND (pMISの場合はn型ウエルが共通のVcc)に接続されているような回路では、ソース電位がp型ウェル電位と異なるため、ソース−ウエル間の耐圧を確保するために逆バイアス耐圧が必要となるので、ソース側をドレイン側と同じ構造としている。すなわち、例えばnMISの場合、p型ウエルに逆バイアス耐圧として−16.5V程度、nMISのソースに1.5V程度が印加されるのでソース−ウエル間の耐圧を確保するためソース側をドレイン側と同じ構造されており、40V以上の耐圧を確保できる構造とされている。このとき、低耐圧MISのソース−ウエル間の耐圧は10V程度を確保できる構造となっている。すなわち、高耐圧MISのソース−ウエル間の耐圧は、低耐圧MISのソース−ウエル間の耐圧よりも大きくなるように形成されている。このような回路としては、例えば出力回路や昇圧回路等が例示できる。しかしながら、ソース−ウエル間で電位差の生じないような回路では、ソース−ウエル間の耐圧を確保するための逆バイアス耐圧が必要とならないので、ドレイン側のみを高耐圧構造とすることができる。このような構造とすることで、MISのサイズを縮小することが可能となり、半導体チップ面積のサイズを縮小することができる。
本実施の形態3では、前記実施の形態1,2の構造の高耐圧MISと、低耐圧MISとを同一の基板1Sに持つ半導体装置の製造方法の一例を図16〜図63により説明する。なお、図16〜図63中の符号HR1は前記実施の形態1の構造の高耐圧MISの形成領域、符号HR2は前記実施の形態2の構造の高耐圧MISの形成領域、符号LRは低耐圧MISの形成領域をそれぞれ示している。また、高耐圧MISの形成領域HR1,HR2の断面は、それぞれ図1のX−X1線、図10のX3−X3線に相当する箇所の断面図を示している。
本実施の形態4では、高耐圧MISの変形例について説明する。図64はその高耐圧pMISQHp3の一例の要部平面図、図65は図64と同一箇所の平面図であって特に高耐圧pMISQHp3の電界緩和機能を持つp-型の半導体領域PV1とカウンタードープ領域DRとの配置関係を示した要部平面図、図66は図64と同一箇所の平面図であって特に高耐圧pMISQHp3の各半導体領域の様子を示した要部平面図、図67は図64と同一箇所の平面図であって特に活性領域L内における半導体領域の様子を示した要部平面図、図68は図64〜図67のX5−X5線の断面図、図69は図64〜図67のX6−X6線の断面図、図70は図64〜図67のY4−Y4線の断面図をそれぞれ示している。なお、ここでも、高耐圧pMISに本発明を適用した場合について説明するが、p、nの導電型を逆にすることで、高耐圧nMISに本発明を適用することもできるのは実施の形態1と同様である。また、図66および図67は平面図であるが図面を見易くするため各半導体領域にハッチングを付す。
本実施の形態5では、前記実施の形態4の高耐圧MISの変形例であって、ソース−ウエル間に大きな耐圧を必要としない場合の高耐圧MIS構造の一例を説明する。
本実施の形態6では、前記実施の形態4,5の構造の高耐圧MISと、低耐圧MISとを同一の基板1Sに持つ半導体装置の製造方法の一例を図78〜図101により説明する。なお、図78〜図101中の符号HR3は前記実施の形態4の構造の高耐圧MISの形成領域(X5−X5)、符号HR4は前記実施の形態5の構造の高耐圧MISの形成領域(X7−X7)、符号LRは低耐圧MISの形成領域をそれぞれ示している。
