          Application No.09/609,652                                                   


               The claimed invention relates to an integrated electronic              
          device having first and second electrodes formed, respectively,             
          on first and second substrates.  An electronic connection                   
          connecting the first and second electrodes is formed that                   
          consists of first, second, and third solder regions arranged in             
          series between the electrodes.  The first and second electrodes             
          are made of different materials that, respectively, are repellant           
          and adhesive to molten solder.                                              
               Claim 25 is illustrative of the invention and reads as                 
          follows:                                                                    
               25.  An integrated electronic device comprising:                       
               a first substrate having a first electrode formed on a first           
          surface of the first substrate;                                             
               a second substrate having a second electrode formed on a               
          first surface of the second substrate, the second substrate                 
          opposing to the first substrate so that the second electrode is             
          aligned to the first electrode; and                                         
               an electronic connection connecting the first electrode with           
          the second electrode, the electronic connection consisting of               
          first, second, and third solder regions arranged in series                  
          between the first and second electrodes such that the first                 
          region is electrically connected with the first electrode and the           
          second region while the third region is electrically connected              
          with the second electrode and the second region, wherein the                
          first and second electrodes are made of different materials from            
          each other.                                                                 




                                         -2–2
