Nangate open cell library

[Eman kamel]

hello every body
i am using open cell library for 45 nm technology
i am trying to get technology information for semi global metal layer
the lef file contain 8 metal layers, i do not know which layer is considered semi global?
also if i used metal 5 layer as an example i found

LAYER metal5

how this give me link width ,height , thickness and spacing in units of micrometer?
thanks in advance
