This disclosure describes a process of generating a planarizing polyimide based dielectric film on a substrate with conducting metal pattern, wherein the process comprised steps of: (a) providing a dielectric film forming composition comprising at least one fully imidized polyimide polymer and at least one solvent; and (b) depositing the dielectric film forming composition onto a substrate with conducting metal pattern to form a dielectric film, wherein the difference in the highest and lowest points on a top surface of the dielectric film is less than about 2 microns.

A differential type non-volatile memory circuit comprising a differential sensing circuit, a differential data line pair, a memory cell array, and a differential bit line pair is provided. The differential sensing circuit has a differential input terminal pair and a differential output terminal pair. The differential data line pair is electrically connected to the differential input terminal pair of the differential sensing circuit.
