          Appeal No. 1999-1517                                                        
          Application No. 08/837,523                                                  


               We affirm.                                                             
               We will consider the two rejections separately.                        
               Rejection under 35 U.S.C. § 112, fist paragraph                        
               Claims 11 through 30 are rejected for failing to provide               
          an adequate written description of the invention (answer at                 
          page 3).  According to the examiner, the specification as                   
          originally filed                                                            





          does not provide adequate support for the phrase “without                   
          driving essentially any dopant of the first conductivity type               
          through the insulating layer” see independent claims 11 and                 
          30, id.                                                                     
               The written description requirement serves “to ensure                  
          that the inventor had possession, as of the filing date of the              
          application relied on, of the specific subject matter later                 
          claimed by him; how the specification accomplishes this is not              
          material."  In re Wertheim, 541 F.2d 257, 262, 191 USPQ 90, 96              
          (CCPA 1976).  In order to meet the written description                      
          requirement, the appellants do not have to utilize any                      
                                          5
