                Appeal No. 1998-1727                                                                                                         
                Application No. 08/340,097                                                                                                   



                                                                OPINION                                                                      

                         We reverse the aforementioned rejections.  We need to address only claims 1 and                                     
                 24, which are the independent claims.                                                                                       
                         The de Lyon reference describes a process for forming ternary II-VI                                                 
                 semiconductor films (16) on a silicon substrate (12) by first depositing a monolayer of                                     
                 arsenic (14) or other group V metal on a cleaned surface of the substrate.  The ternary II-                                 
                 VI semiconductor film is then formed over the arsenic monolayer, either directly thereon                                    
                 or on top of an intermediate buffering layer (18). (Cols. 3 and 4; Fig. 2).  The de Lyon                                    
                 reference describes the importance of using a single monolayer of arsenic on the cleaned                                    
                 silicon surface in order to avoid disruption of the epitaxial process.  (Col. 3, l. 67 to col.                              
                 4, l. 9).                                                                                                                   
                         Thus, the de Lyon reference discloses forming a passivation layer having a                                          
                 thickness of one monolayer on a cleaned silicon substrate and forming a lattice matched                                     
                 layer on the passivation layer.  The de Lyon reference does not anticipate the subject                                      
                 matter of claim 1 because the reference discloses the use of a passivation layer having                                     
                 more than one monolayer will disruption of the epitaxial process.  In order for a claimed                                   
                 invention to be anticipated under 35 U.S.C. § 102, all of the elements of the claim must                                    
                 be found in one reference.  See Scripps Clinic & Research Found. v. Genentech Inc.,
