Description
本実施の形態に係る半導体装置について説明する前に、従来の半導体装置について説明する。図1は、従来の半導体装置の構成を示す上面図であり、各構成が占める領域が示されている。図2は、従来の半導体装置の構成を示す断面図である。図1に示すように、半導体基板21と、デジタルブロック1と、アナログブロック2と、基板電位固定領域4と、パッド6,8とを備える。
実施の形態1では、デジタルブロック1より発生するノイズを、パッド8を介してアナログ回路のグランド電位に吸収させた。この場合、ノイズによりアナログ回路のグランドが多少なりとも変動する。そのため、グランドで電位を固定していたアナログ回路の精度が劣化する要因となりうる。
本実施の形態では、図7に示すように、アナログブロック2に所定の半導体素子群3が設けられている。この半導体素子群3は、複数の所定の半導体素子、例えば、容量素子19をグループ化してなる。本実施の形態に係る半導体装置では、デジタルブロック1より発生するノイズから、半導体素子群3をさらに保護するため、基板電位固定領域20は、図7および図8に示すように、半導体素子群3における個々の容量素子19の各々を平面視で囲む。他の構成については、実施の形態1と同様であるものとする。
