1. A method for manufacturing a polyimide substrate, comprising steps of:
providing a diamine containing a bis(oxazole) structure;
polymerizing a fluorine-containing dianhydride with the diamine containing the bis(oxazole) structure to form a polyamic acid containing oxazole and fluorine; and
cyclodehydrating the polyamic acid containing oxazole and fluorine to produce a polyimide containing oxazole and fluorine, and forming the polyimide substrate by film formation of the polyimide containing oxazole and fluorine,
wherein a chemical formula of the polyimide containing oxazole and fluorine is:,
