Standard Cell Library - .lib file

[graphene]

1) I know that once you have a lib file, contents other than the individual cell information is considered tech part of lib file, is that correct ?
2) Any idea finding the technology lib file ... ?

Liberty files (.lib) contains information about timing and power of a standard cells. Technology information, such as cell geometry, layers and via width, spacing, size, are not includes in Liberty. There are another special library formats that includes tech information needed for Place&Route tools. For example, Cadence Encounter requires LEF files (Library Exchange Format).

.libs have global as well as cell level atributes

Global attributes like
voltage map (0.9 1.2)
PVTs

Cell attributes like
power or signal pin
timing for specified arcs
leakage etc.
