BJTs have almost ruled the industry for quite sometime but Going into further technologies, power is the governing factor in almost every design. Less Power consumption is the main reason. hence cmos integration is higher compared to BJTs. Other reasons have been cited above.

hi xhl, how can u say that cmos is not faster than bjt...
in bjts we have two carriers while in case of cmos we have only electrons and the mobility of electrons is much higher than ur holes.....thts y the cmos is faster than bjt.....
