          Appeal No. 95-3017                                                          
          Application 07/952,061                                                      


          cally recited as a region 22 such as in Figure 2 comprising a               
          pattern of subresolution features.  The pattern is made up in               
          the exemplary Figure 2 of subregions 22a and 22b.  To the extent            
          claimed, it is clear to us from the above referenced portions of            
          columns 3 to 5 of Pease as relied upon by the examiner that it              
          is the disclosed trenches 118 in representative Figure 1 of this            
          reference which correspond to the claimed pattern of features               
          that are below the resolution of the printer set forth in claim             
          1 on appeal.  This pattern is set forth in the generic/master               
          mask 11 at the bottom of Figure 2.  This region is also pertinent           
          to the subject matter of dependent claim 2 on appeal.                       
               Although it is clearly the intent of Pease in the above                
          noted referenced portions of this reference not to image the                
          trenches on the underlying die, it is revealed at column 5,                 
          lines 27 to 31 that some light, “a small amount of light” may               
          be projected on the region of the die corresponding to the                  
          positions of the trenches.  This teaching clearly indicates                 
          to the artisan that there is some attenuation of the light                  
          corresponding to the trench location in such a manner as to                 
          correspond to the reduced portion of radiation incidence upon               
          the die to the extent recited in claim 1 on appeal.  As such,               



                                          6
