What's this kind of layout means in a BiCMOS process

[refugee]

This is a layer of poly, and I don't know exactly what this graph stands for.

I think it might be a bjt. Is it a PNP or NPN? Vertical one or lateral one?

And also what's the B,E,C.

Your kindness help will be appreciated.

It can not directly judged frpm the graph that it is a PNP or NPN,because of the unkown doping type.but you can judge the structure.the Y is poly emmiter ,X is the base contact,the Z is collector,it is a vertical one.
