Abstract:
A microchip has a resin substrate, which is provided with a first surface whereupon a channel groove is formed and a second surface on the opposite side to the first surface, and the microchip also has a resin film bonded on the first surface. A projection area is larger than the area of the first surface of the resin substrate when the resin substrate is viewed from a direction orthogonally intersecting with the first surface. Thus, warpage of the microchip can be suppressed at the time of thermally bonding the resin substrate and the resin film by a roller.
Abstract:
A composite object comprises two components (2a, 2b) made of an oxidic material, which at an elevated temperature conducts ions, said components being connected to each other in a medium-tight manner by way of a solder bridge (4) in a connecting region (6) located in between. In order to form a reliable connection, it is proposed that the solder bridge is formed by a low-melting tin alloy that has a weight proportion of at least 65% tin and a melting point of no more than 350ºC and comprises at least one activating metal as an alloying constituent.
Abstract:
Provided are a microchip enabling accurate analysis by preventing a resin film from being deflected into a flow path groove to eliminate the stagnation of a liquid sample and a method of manufacturing the microchip. This microchip includes a flow path that is formed by joining a resin film onto the groove-formed surface of a resin substrate. The deflection angle of the resin film in the sectional surface of the flow path in the width direction is made to be 0 to less than 30° at respective positions of the flow path

Abstract:
Without sacrificial layer etching, a microstructure and a micromachine are manufactured. A separation layer 102 is formed over a substrate 101, and a layer 103 to be a movable electrode is formed over the separation layer 102. At an interface of the separation layer 102, the layer 103 to be a movable electrode is separated from the substrate. A layer 106 to be a fixed electrode is formed over another substrate 105. The layer 103 to be a movable electrode is fixed to the substrate 105 with the spacer layer 103 which is partially provided interposed therebetween, so that the layer 103 to be a movable electrode and a layer 106 to be a fixed electrode face each other.
