Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and a method for manufacturing a remakeable connection for a single-mode optical waveguide.SOLUTION: The single-mode optical waveguide 10 includes a core 12 surrounded by a cladding consisting of an inner soft layer 14 and an outer harder layer 16. The outer layer 18 has a grating structure on its inner surface, whose spatial frequency is the same as that of the guided mode. The thickness of the inner cladding is sufficient to keep the grating outside the mode field in undeformed regions of the waveguide, so that normally no out-coupling of the light occurs. Connections are made by crossing two such waveguides 10 at an angle and pressing them together. This results in deformation of the two waveguides such that the gratings are brought into proximity with the cores. Light is coupled out of one waveguide and into the other in the deformed region, resulting in a self-aligning optical connection. The out-coupled light propagates normal to the waveguide axis, so that errors in the crossing angle cause little change in efficiency. Because the cladding system is sufficiently resilient to recover after deformation, the connection is remakeable.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and system for determining alignment data of structures on a wafer or a chip. SOLUTION: The method and the system are provided for determining alignment data of structures on a work piece such as a wafer or a chip coated with an over bump applied material like resin or a film, for example, and using the data to align the wafer or the chip in a following operation such as dicing or joining. One of data for alignment is generated by identifying a location of the structure by varying the depth of a focus upon a work piece to determine an approximately maximum value of an SNR from an image captured by optical scanning. The SNR above a threshold can be employed. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a process capable of connecting a semiconductor chip having an alignment pattern to a substrate, with accurate positional relationship being maintained. SOLUTION: After an alignment information 610 of a semiconductor chip having an alignment pattern is scanned and stored (620), the semiconductor chip in which a bump formation surface is coated with a curable under fill coating is generated. Then, by utilizing the stored alignment information, alignment (650) is executed between the semiconductor chip and a substrate having an electrical mutual connection structure. The semiconductor chip and the substrate are made to contact to each other after alignment so that the under fill coating is cured (660) for electrical jointing and sealing between the semiconductor chip and the substrate at the same time.

PROBLEM TO BE SOLVED: To provide an apparatus and a method for manufacturing multiple remakeable single-mode waveguide connections. SOLUTION: A single-mode optical waveguide has a core surrounded by a cladding consisting of an inner soft layer and an outer harder layer.

Abstract:
PROBLEM TO BE SOLVED: To prevent illegal resale by forming at least one of coat and code on an item and determining whether the item has been resold from an authorized merchant to an unauthorized merchant by checking the coat or code. SOLUTION: This identifier is extremely difficult if not impossible to remove. The identifier has its allocation and encoded code known only to a manufacturer. When the manufacturer suspects that parallel commercial transaction is occurring, he easily identifies an unauthorized reseller and can take appropriate countermeasures to prevent unauthorized activity. The system 50 includes a processor 51, a special coat/ruled code to be attached onto an item of interest and a detector 53 for determining information contents of the special coat/ scribing code. Although the detector 53 is shown separately from the processor 51, the detector can incorporate the processor therein.
