摘要:
A method for protecting a material of a microstructure comprising the material and a noble metal layer against undesired galvanic etching during manufacture, the method comprises forming on the structure a sacrificial metal layer having a lower redox potential than the material, the sacrificial metal layer being electrically connected to the noble metal layer.

摘要:
A vertically integrated structure includes a micro-electromechanical system (MEMS) and a chip for delivering signals to the MEMS. The structure includes a metal stud connecting a surface of the chip and the MEMS; the MEMS has an anchor portion having a conducting pad on an underside thereof contacting the metal stud. The MEMS is spaced from the chip by a distance corresponding to a height of the metal stud, and the MEMS includes a doped region in contact with the conducting pad. In particular, the MEMS may include a cantilever structure, with the end portion including a tip extending in the vertical direction. A support structure (e.g. of polyimide) may surround the metal stud and contact both the underside of the MEMS and the surface of the chip. A temporary carrier plate is used to facilitate handling of the MEMS and alignment to the chip.

A vertically integrated structure includes a micro-electromechanical system (MEMS) and a chip for delivering signals to the MEMS. The MEMS has an anchor portion having a conductor therethrough, by which it is connected to a substrate. The chip is attached to the MEMS substrate in a direction normal to the substrate surface, so as to make a conductive path from the chip to the MEMS. The chip may be attached by bonding the conductor to C4 metal pads formed on the chip, or by bonding the conductor to metal studs on the chip. The MEMS substrate may be thinned before attachment to the chip, or may be removed from the underside of the MEMS. A temporary carrier plate is used to facilitate handling of the MEMS and alignment to the chip.
摘要:
A device for contacting and/or modifying a surface having a cantilever connected to an almost plane carrier element staying apart from said surface, said cantilever having a tip at its loose end being in close contact to said surface. It is proposed that the cantilever stand out of the plane of said carrier element. Further, a method for producing the cantilever having a tip at its loose end. The device is suitable for thermomechanical writing and thermal readout of binary information, lithographic and imaging techniques, and for surface modification.

Tips including a platinum silicide at an apex of a single crystal silicon tip are provided herein. Also, techniques for creating a tip are provided. The techniques include depositing an amount of platinum (Pt) on a single crystal silicon tip, annealing the platinum and single crystal silicon tip to form a platinum silicide, and selectively etching the platinum with respect to the formed platinum silicide.
摘要:
A method for producing an integrated device. A source substrate is provided, the source substrate carrying one or more components to be attached to a receiver surface having a uneven topography. The source substrate includes a deformable layer on a surface on which the one or more components are carried. The source substrate is aligned such that said one or more components carried thereon are associated with contact areas of the receiver surface. The source substrate and the receiver surface are moved towards each other such that the one or more components are brought into contact with the contact areas wherein the deformable layer is at least partially deformed. The source substrate is removed such that the one or more of the components remain located on the contact areas of the receiver surface.
