Appeal No. 1997-0439 Application 08/348,414 to 17 have been canceled. BACKGROUND The subject matter on appeal is directed to optical waveguides and corner coupling of electronic devices using an interconnect substrate (see specification, page 1). More specifically, appellants disclose an interconnect substrate (see appellants’ Figure 1) and a method of making an interconnect substrate having a cleaved end surface which creates a corner edge contact (see specification, pages 1 to 2; Brief, page 3). Appellants recognized that by cutting or cleaving a channel 109 in an end surface 105 and an upper surface 104 after an electrically conductive material (e.g., solder) has been added, electronic devices 152 can be more easily connected and coupling can be performed more easily and efficiently (see specification, page 1). Representative independent apparatus claim 8 is reproduced below: 8. An interconnect substrate comprising: a substrate having a first surface with an electrical trace; a channel formed in the first surface and filled with an electrically conductive material; the substrate being cut through the first surface and the channel to form an end surface, the channel and the electrically conductive material defining a contact in the end surface and a contact in the first surface; and the electrical trace being operably coupled to the electrically conductive material in the channel. 2Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
