Description
Oleg Semenov et al.,IEEE Transactions on Device and Materials Reliability, Vol. 6, No. 1, 2006, pp.17-27.
前記半導体基板の表面部分であって、かつ隣り合う前記トランジスタ間に設けられた複数の音響反射層と、
を備え、前記音響反射層は、前記ゲート電極の長さ方向に対して斜め方向に位置するように配置されており、
前記半導体基板は、シリコン基板であり、
前記ゲート電極の長さ方向は、前記シリコン基板の結晶方位<100>に平行に設けられていることを特徴とする。
図1から図4に、本発明の第1実施形態による、高周波電力増幅器用のMOS型トランジスタのレイアウトを示す。図1から図4の(a)は平面図、(b)は(a)のB−Bにおける断面図を示す。また図5は本実施形態のMOSトランジスタの三次元レイアウト、図6は、図1−図4に示したトランジスタの等価回路である。図1および図6に示されたMOSトランジスタは、大きなドレイン電流を流すことができるように、それぞれ3個のトランジスタに分割され、個々のトランジスタを並列接続することにより構成されている。ここでは、簡単のために3個のトランジスタの例について図示したが、チャネル幅Wをより大きくするためには、さらに並列接続の個数を増やすことが好ましい。
また図9、図10に示したような第2実施形態を取ることも可能である。図9に、本発明の第2の実施の形態による、高周波電力増幅器用のMOS型トランジスタのレイアウトを示す。図9の(a)は平面図、(b)は(a)のB−Bにおける断面図を示す。また、図10は本実施形態の三次元によるMOSトランジスタの三次元レイアウトである。
次に、本発明の第3実施形態による無線携帯端末の送信回路のブロック図を図11に示す。本実施形態の無線携帯端末は、第1または第2実施形態のいずれかの高周波電力増幅器を備えている。この送信回路では、図示しないベースバンド回路から直交デジタル信号IとQを受け取り、局所発振器LOのミキサMIX1、MIX2において位相が90度異なるように高周波信号により変調される。そして、この変調された信号が加算器ADで加算された後、バンドパスフィルタBPFを通過する。バンドパスフィルタBPFを通過した信号は電力増幅器PAにより増幅され、アンテナANTから電磁波として輻射される。電力増幅器PAとして、第1または第2実施形態のいずれかの高周波電力増幅器が用いられる。
