What is the Difference between Substrate & Base material in Printed Circuit Board?

What is the difference between Substrate material in PCB and in semiconductor [VLSI] ?Is the VLSI substrate Cu plate?

Is the substrate of VLSI a fibre glass or it is something else?

What is the base material/Substrate in VLSI?

VLSI ICs are generally made of silicon.

PC Boards are generally made of fiberglass material, like FR4.
