摘要：

Compared　with　BVCEO,　BVCES　is　more　related　to　collector　optimization　and　more　practical　significance,　so　that　BVCES　×　fT　rather　than　BVCEO　×　fT　is　employed　in　representing　the　limit　of　the　product　of　the　breakdown　voltage-cutoff　frequency　in　SiGe　HBT　for　collector　engineering　design.　Instead　of　a　single　decrease　in　collector　doping　to　improve　BVCES　×　fT　and　BVCEO　×　fT,　a　novel　thin　composite　of　N-　and　P+　doping　layers　inside　the　CB　SCR　is　presented　to　improve　the　well-known　tradeoff　between　the　breakdown　voltage　and　cut-off　frequency　in　SiGe　HBT,　and　BVCES　and　BVCEO　are　improved　respectively　with　slight　degradation　in　fT.　As　a　result,　the　BVCES　×　fT　product　is　improved　from　537.57　to　556.4　GHz•V,　and　the　BVCEO　×　fT　product　is　improved　from　309.51　to　326.35　GHz•V.　©　2015　Chinese　Institute　of　Electronics.
