    Abstract: PROBLEM TO BE SOLVED: To provide a compound substrate which is affixed with a piezoelectric substrate and a support substrate to each other via an organic adhesive layer, and a formation method which allows the formation of a desired metal pattern with high accuracy by using lift-off processing. SOLUTION: A composite substrate 10 is obtained, by bonding the piezoelectric substrate 11 transparent to light used for photolithography and the supporting substrate 12 for supporting the piezoelectric substrate 11 via the organic adhesive layer 13. At least one among the support substrate 12 and the organic adhesive layer 13 of the composite substrate 10 can absorb light which is used for photolithography. This allows, in the compound substrate 10, a desired metal pattern to be formed on a surface of the piezoelectric substrate by lift-off processing using photolithography.

    Abstract: PROBLEM TO BE SOLVED: To suppress chipping of an edge part of a piezoelectric substrate of a compound substrate formed by sticking the piezoelectric substrate and a support substrate together when a surface of the piezoelectric substrate is processed with polishing abrasive grains.
    SOLUTION: A silicon substrate 12 is prepared, and also an LT substrate is prepared which has an external diameter taking of a margin corresponding to a position shift made in sticking into consideration for a length obtained by subtracting a beveled part from the external diameter of the silicon substrate 12 (Fig.5(a)). Then the LT substrate 10 has its backsides coated with an organic adhesive 13 and is stuck on the silicon substrate 12 to form a stuck substrate 16 (Fig.5(b)). Further, slurry containing polishing abrasive grains is supplied to between a surface of the LT substrate 10 and a polishing surface plate and the surface of the LT substrate 10 is polished by the polishing surface plate to polish the surface into a mirror plane while reducing the thickness of the LT substrate 10 (Fig.5(c)).

    Abstract: PROBLEM TO BE SOLVED: To make it possible for two 4-channel transceivers having a transmission diode string and a reception diode string installed separately to use a single 8-fiber ribbon. SOLUTION: An optical head has an optical head main body 40 having a proximal surface and a distal surface, and eight optical fiber segments 48 are extended via the main body 40. The respective segments 48 have fiber end parts at respective proximal surface and distal surface. The fiber end parts at the proximal surfaces are grouped into two fiber end part strings consisting of four fiber end parts which are equally separated from each other to be positioned respectively optically by a transmission chip 26 and a reception chip 28. The fiber end pars at the distal surface consist of a single string of the eight fiber end parts equally separated from each other.
