Abstract: A liquid output portion is arranged above and moves relative to a semiconductor substrate with determined film formation and non-film-formation regions. The liquid output portion continuously outputs a liquid in a constant amount to the substrate. Below the liquid output portion is a liquid shut-out-portion. A liquid controlled to spread in a constant amount is continuously output from the liquid output nozzle to the substrate. While the nozzle and the substrate relatively move, the liquid is supplied to a first region, and the liquid is supplied to a second region in such a way that the liquid supplied and spread in the second region is in contact with the liquid supplied and spread in the first region. Where projections and depressions are formed on the surface of the substrate, an amount of the liquid supplied varies depending upon the ratio between the projections and depressions.

Furthermore all these improvements can be made with less manufacturing time and cost.

Abstract: The present invention is predicated on applicants' discovery that inhomogeneity in films deposited on heated heterogeneous substrates can be substantially reduced by patterning the large area metal structures. Specifically, metal structures having areas in excess of about 2 mm.sup.2 are patterned so that the metal is within 1 mm of a metal edge. Thus, for example, a normally solid chromium bonding pad on a glass substrate is conveniently made as a patterned, open grid of 1 mm chromium lines.

The first pole piece layer and the first insulation layer have planar surfaces which preferably lie in a common plane, the zero throat height being defined at the point where the planar surface of the first pole piece layer first meets the planar surface of the first insulation layer within the head.

Further, when a photoresist layer is spun onto the partially completed head for the construction of the pole tip of the second pole piece light directed into the photoresist layer for photo-imaging the pole tip does not reflect into the photoresist layer adjacent the pole tip.
