Abstract:
A thermo-pneumatic micro pump chip applicable to a micro bio chip and a manufacturing method thereof are provided to increase precision of flow control of a pump by bonding a poly dimethyl siloxane(PDMS) chip with a glass chip integrally. A thermo-pneumatic micro pump chip(100) that is applicable to a micro bio chip comprises a glass chip(10) and a PDMS chip(20) that are integrally bonded to each other. The glass chip is equipped with a heater(11) and a sensor. In addition, the PDMS chip is formed on an upper surface of the glass chip and moves fluid sample in a desired direction.
Abstract:
A method of stimulating a MicroElectroMechanical Systems (MEMS) structure (e.g. a cantilever), and an optical sensor for use in such a method, using optical radiation pressure instead of electrostatic pressure, or the like. An optical pulse creates optical radiation pressure which stimulates movement of the MEMS structure and then movement of the MEMS structure may be measures. An interrogating light may be input after the optical pulse to measure movement of the MEMS structure. Advantageously, the same light source can be utilised to stimulate movement of the MEMS structure and to measure movement of the MEMS structure.
Abstract:
The present disclosure provides a method for manufacturing a chip that includes a microchannel (10). The method includes steps of: fixing a cationic polymer having a quaternary onium group on at least one surface of each of a pair of resin substrates (1,2); and joining the resin substrates together at the surfaces on which the cationic polymer has been fixed.

Abstract:
The invention relates to a microelectronic component assembly comprising a plurality of substrates, and a corresponding method of production. Said microelectronic component assembly comprising a plurality of substrates has a first substrate (C1), which is designed as a circuit substrate of a first level of integration, a second substrate (C2), which is designed as a circuit substrate of a second level of integration, and a third substrate (C3), which is designed as a MEMS sensor substrate and which is bonded onto the second substrate (C2). The second and the third substrate is bonded onto the first substrate (C1). The first level of integration is substantially higher than the second level of integration.
Abstract:
An integrated package of at least one environmental sensor and at least one MEMS acoustic sensor is disclosed. The package contains a shared port that exposes both sensors to the environment, wherein the environmental sensor measures characteristics of the environment and the acoustic sensor measures sound waves. The port exposes the environmental sensor to an air flow and the acoustic sensor to sound waves. An example of the acoustic sensor is a microphone and an example of the environmental sensor is a humidity sensor.
