Abstract
A method for fabricating a pair of patterned target layers within a microelectronic product employs a pair of patterned etch mask layers of different thicknesses. The pair of patterned etch mask layers of different thicknesses provides that the pair of patterned target layers may be formed with individual linewidth control, absent fabrication or modification of a photomask to realize the same result. The method is particularly useful for fabricating pair of gate electrodes for use within CMOS devices.
