Abstract:
A method of making a system-in-package device, and a system-in-package device is disclosed. In the method, at least one first species die with predetermined dimensions, at least one second species die with predetermined dimensions, and at least one further component of the system-in-device is included in the system-in package device. At least one of the first and second species dies is selected for redimensioning, and material is added to at least one side of the selected die such that the added material and the selected die form a redimensioned die structure. A connecting layer is formed on the redimensioned die structure. The redimensioned die structure is dimensioned to allow mounting of the non-selected die and the at least one further component into contact with the redimensioned die structure via the connecting layer.

Abstract:
A method of embedding material in a glass substrate is provided. The method includes providing a glass composition and a mold substrate having a patterned surface defining a recess therein. The mold substrate is formed from a material having a higher reflow temperature than the glass composition. A surface wettability of the patterned surface is increased relative to the glass composition. At least a portion of the glass composition is flowed into the recess defined by the patterned surface of the mold substrate, followed by solidifying the glass composition to form a solidified glass layer. Material is removed from the solidified glass layer until a portion of the underlying patterned surface of the mold substrate is exposed with at least a portion of the mold substrate embedded in the solidified glass layer to thereby form the glass substrate having the material embedded therein.

The Invention concerns to a micro-actuator device for the use in biochip or bio-system. In order to achieve a micro-actuator device for the use as a micro pump in biosensors or bio-systems, or at least bio-chips, by which the actuation can be steered very precisely and effective, the solution is that the micro actuator consist of a photosensitive actuator element (1), which can be deformed from a reversal basic-form into an activated deformation form by photonic activation of a light source (3, 4, L1, L2) in order to generate with this controlled movement a defined flow in a gas or a liquid.
Abstract:
The present invention relates to a method for the production of membranes that can be electrically and/or magnetically activated, particularly for switches or pumps. In the method, microparticles and/or nanoparticles (5) having magnetic and/or electric properties are mixed with a matrix material in a flowable state, which has elastic properties after solidification. The matrix material is applied to a substrate as a layer (1), and a distribution of the particles in the layer (1) is selectively modified by means of one or more electric and/or magnetic fields in order to achieve an accumulation (2, 3) of the particles (5) on one or a plurality of locations in the layer (1). The layer (1) is subsequently solidified using the accumulated particles in order to form one or more membranes (16). The invention also relates to a magnetic actuator having such a membrane. The method enables the use of elastic membranes having magnetic, or magnetizable, particles incorporated therein, without having an adverse influence on the elastic properties in certain regions of the membrane.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von elektrisch und/oder magnetisch ansteuerbaren Membranen, insbesondere für Schalter oder Pumpen. Bei dem Verfahren werden Mikro- und/oder Nanopartikel (5) mit magnetischen und/oder elektrischen Eigenschaften mit einem in fließfähigem Zustand befindlichen Matrixmaterial vermischt, das nach einer Verfestigung elastische Eigenschaften aufweist. Das Matrixmaterial wird als Schicht (1) auf ein Substrat aufgebracht und eine Verteilung der Partikel in der Schicht (1) mit einem oder mehreren elektrischen und/oder magnetischen Feldern gezielt verändert, um eine Anhäufung (2, 3) der Partikel (5) an einer oder mehreren Stellen der Schicht (1) zu erhalten. Die Schicht (1) wird anschließend mit den angehäuften Partikeln zur Bildung einer oder mehrerer Membranen (16) verfestigt. Die Erfindung betrifft auch einen magnetischen Aktor mit einer derartigen Membran. Das Verfahren ermöglicht die Nutzung von elastischen Membranen mit eingelagerten magnetischen oder magnetisierbaren Partikeln, ohne die elastischen Eigenschaften in bestimmten Bereichen der Membran negativ zu beeinflussen.
Abstract:
Plastic microfluidic structures having a substantially rigid diaphragm that actuates between a relaxed state wherein the diaphragm sits against the surface of a substrate and an actuated state wherein the diaphragm is moved away from the substrate. As will be seen from the following description, the microfluidic structures formed with this diaphragm provide easy to manufacture and robust systems, as well readily made components such as valves and pumps.
