摘要:
A process for filling one or more etched holes defined in a frontside surface of a wafer substrate. The process includes the steps of: (i) depositing a layer of a photoimageable thermoplastic polymer onto the frontside surface and into each hole; (ii) reflowing the polymer; (iii) selectively removing the polymer from regions outside a periphery of each hole, the selective removing comprising exposure and development of the polymer; (iv) optionally repeating steps (i) to (iii) until each hole is overfilled with the polymer; and (v) planarizing the frontside surface to provide one or more holes filled with a plug of the polymer. Each plug has a respective upper surface coplanar with the frontside surface.

The present invention relates to MEM switches. More specifically, the present invention relates to a system and method for making MEM switches having a common ground plane. One method for making MEM switches includes: patterning a common ground plane layer on a substrate; forming a dielectric layer on the common ground plane layer; depositing a DC electrode region through the dielectric layer to contact the common ground plane layer; and depositing a conducting layer on the DC electrode region so that regions of the conducting layer contact the DC electrode region, so that the common ground plane layer provides a common ground for the regions of the conducting layer.

A method for depositing material on a channel plate such that the material is registered to one or more channels formed in the channel plate includes filling at least one of the channels with a resist that is not wetted by the material; depositing the material on at least a region of the channel plate that includes at least part of the resist, the material registering with at least one channel edge as a result of the material's abutment to the resist; and then removing the resist. The method may be used, in one embodiment, to apply an adhesive or gasket material that is used in assembling a switch.
摘要:
A method for producing optically planar surfaces for micro-electromechanical system devices (MEMS), comprising the steps of: depositing a first layer over a substrate; forming a channel in the first layer wherein the channel has a depth defined by a thickness of the first layer and a width greater than 10 microns; depositing a second layer over the first layer wherein the second layer has a thickness greater than the depth of the channel and is composed of a different material than the first layer; removing the second layer from outside the channel leaving an overlap at the edge of the channel; and polishing the second layer that fills the channel to obtain an optically planar surface for the MEMS device.

A semiconductor arrangement and method of formation are provided. The semiconductor arrangement includes an electro-wetting-on-dielectric (EWOD) device. The EWOD device includes a top portion over a bottom portion and a channel gap between the top portion and the bottom portion. The bottom portion includes a driving dielectric layer over a first electrode, a second electrode and a first separating portion of an ILD layer between the first electrode and a second electrode. The driving dielectric layer has a first thickness less than about 1,000 Å. An EWOD device with a driving dielectric layer having a first thickness less 1000 Å requires a lower applied voltage to alter a shape of a droplet within the device and has a longer operating life than an EWOD device that requires a higher applied voltage to alter the shape of the droplet.

A process for filling one or more etched holes defined in a frontside surface of a wafer substrate. The process includes the steps of: (i) depositing a layer of a thermoplastic first polymer onto the frontside surface and into each hole; (ii) reflowing the first polymer; (iii) exposing the wafer substrate to a controlled oxidative plasma; (iv) optionally repeating steps (i) to (iii); (v) depositing a layer of a photoimageable second polymer; (vi) selectively removing the second polymer from regions outside a periphery of the holes using exposure and development; and (vii) planarizing the frontside surface to provide holes filled with a plug comprising the first and second polymers, which are different than each other. Each plug has a respective upper surface coplanar with the frontside surface.
