          Appeal No. 1999-2834                                                          
          Application No. 08/483,731                                                    


                    99.  A semiconductor processing lithography apparatus               
               for maskless pattern generation comprising:                              
                    an array of radiation source cells arranged in rows and             
               columns, the array being formed on a flexible insulating                 
               membrane held in a support frame;                                        
                    control logic mounted on the membrane for controlling               
               the cells, wherein each cell comprises:                                  
                    a source of radiation;                                              
                    a target on which the radiation is incident for                     
               generating X-rays; and                                                   
                    an aperture for emitting the x-rays from the target                 
               onto a surface to be exposed.                                            
               No references were relied on by the examiner.                            
               Claims 99 through 104 stand rejected under the first                     
          paragraph of 35 U.S.C. § 112 because of a nonenabling disclosure.             
          An excerpt from the grounds of the rejection is as follows                    
          (answer, pages 3 and 4):                                                      
                    The emission of electrons from a cold cathode and                   
               their acceleration toward a target with sufficient                       
               energy to cause the generation of x rays requires the                    
               application of substantial potential difference between                  
               the cathode and the target.  The manner of applying                      
               such potential and appropriately insulating the various                  
               components on the very thin membrane have not been                       
               taught.                                                                  
                    The manner of creating and maintaining a vacuum                     
               within the very thin membrane to encompass the charged                   
               particle and x-ray generators has not been taught.
