摘要： A trench structure and an integrated circuit comprising sub-lithographic trench structures in a substrate. In one embodiment the trench structure is created by forming sets of trenches with a lithographic mask and filling the sets of trenches with sets of step spacer blocks comprising two alternating spacer materials which are separately removable from each other. In one embodiment, the trench structures formed are one-nth the thickness of the lithographic mask's feature size. The size of the trench structures being dependent on the thickness and number of spacer material layers used to form the set of step spacer blocks. The number of spacer material layers being n/2 and the thickness of each spacer material layer being one-nth of the lithographic mask's feature size.

摘要： A method and apparatus for mapping the character and location of small surface variations on a planar surface. Energy is supplied to an object in close proximity to the planar surface to thereby raise the temperature of the object. The object is moved with respect to the planer surface substantially constant. A decrease in temperature of the object is detected when it is in proximity to the variation to define the location and character of the variation. The energy supply may be thermal energy or optical energy but preferably is electrical energy which heats a resistive element. Preferably, the object is the magnetoresistive head of a disk drive assembly. The surface may be that of a magnetic recording material. The change in temperature is detected by monitoring the resistance of the magnetoresistive coil of the head. The energy may be supplied in pulses to obtain higher peek temperatures while avoiding mechanical distortion of the object. It is preferred that the object be positioned with respect to the surface so that when that relative motion between the surface and the object occurs, the object does not contact the surface.
