The production of multilayer ceramic substrates employs screening masks through which molybdenum patterns are screened on ceramic green sheets. It has been found that the longevity of the screening masks as well as the yield of usable masks may be increased dramatically by moving the screening masks fused area outside the fiducial areas, as described below. Fig. 1 illustrates a green sheet screening mask 10 as has been heretofore employed for screening molybdenum patterns on ceramic green sheets. Screening mask 10 includes two metal layers 11 and 12, fused together at 14. Screen layer 11 includes a screening mesh 15, while pattern layer 12 includes the particular pattern 16 which is to be screened on the green sheet.
