Abstract:
A semiconductor device comprising a wiring system having an insulating film and micro-wire or wires of metal conductor formed thereon, said micro-wires having a recess in one side portion thereof to form a cross-sectional reverse L-shape, said reverse L-shape having a foot portion contacting said insulating film and an arm portion supported by said foot portion wherein said arm portion of the micro-wires is longer than said foot portion of the micro-wires, wherein said reverse L-shape provides an enlarged space between adjacent micro-wires to minimize capacitance therebetween, wherein a space between sides of adjacent micro-wires is a sum of a space between adjacent micro-wires (S) and a width of said micro-wires (L), and wherein the recess and the space between adjacent micro-wires, defined by the cross-sectional shape of the micro-wires, are substantially hollow below the arm portion of adjacent micro-wires to minimize the parasitic capacitance and skin effect influence.
