Abstract: The present invention discloses a method for manufacturing a polymer chip. The method first manufactures a plurality of unit mold, and each unit mold has a unit pattern corresponding to a pattern on the surface of the polymer chip for performing an operation. The unit molds are then selected and assembled to form an integrated mold according to a chip draft, and the unit pattern of the unit molds form an integrated pattern. The integrated mold is used in a molding process for manufacturing the polymer chip. The surface topography of the polymer chip is corresponding to the integrated pattern of the integrated mold, and can perform an integrated operation.

Abstract: An optoelectronic transceiver that has integrated optical and electronic components, and can be passively aligned by a flip-chip method and a mechanical method is provided. The optoelectronic transceiver can be constructed by the key components of a circuit board, a silicon sub-mount, at least two IC chips formed on a silicon sub-mount, a microlens array, an optical fiber, and a receptacle for housing the silicon sub-mount, the at least two IC chips, the microlens array and the optical fiber connector in an aligned configuration. The at least two IC chips preferably include a laser diode, a laser diode driver, a photodetector and a photodetector amplifier. The mechanical alignment between a microlens array and a silicon sub-mount is performed by indentations provided in the surfaces of the two parts and the placement of spacer balls in the indentations.
