what is the difference between active and n+ or p+.

Hi
As I know, the active determines the diffusion region.
and N+ (or N select) and P+ (or P select) determine type of diffusion.

it are technology layers. i.e. real diffusion n+ or p+ will be in area, where diffusion and n+(p+) are crossing

Active area is the area in which the transistors will be made ,in proccess with well implant options ,n+ implante usually used to form the n well and p+ the p well.It is a concept against the passive area used to isolating ,passivating ,etc.
n+ and p+ is a concept of dopant concentration .Many areas and steps using the n+ or p+ diffusion and implantation,such as the source ,drain ,the Vt adjustment implantation ,the body contact. The n+ p+ concentraion can varies from e+17 to e+21,all these concentration can be called n+ and p+.
