Abstract: Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and design structures are provided. The method of forming a MEMS structure includes forming fixed actuator electrodes (115) and a contact point on a substrate. The method further includes forming a MEMS beam (100) over the fixed actuator electrodes and the contact point. The method further includes forming an array of actuator electrodes (105') in alignment with portions of the fixed actuator electrodes, which are sized and dimensioned to prevent the MEMS beam from collapsing on the fixed actuator electrodes after repeating cycling. The array of actuator electrodes are formed in direct contact with at least one of an underside of the MEMS beam and a surface of the fixed actuator electrodes.

Abstract: A permanent protective hardmask 40 protects the dielectric properties of a main bulk dielectric layer 30 having a desirably low dielectric constant in a semiconductor device from undesirable increases in the dielectric constant, undesirable increases in current leakage, and low device yield from surface scratching during subsequent processing steps. The protective hardmask 40 further includes a single layer 50 or dual layer 50,60 sacrificial hardmask particularly useful when interconnect structures such as via openings and/or lines are formed in the low dielectric material during the course of making the final product. The sacrificial hardmask layers 50,60 and the permanent hardmask layer 40 may be formed in a single step from a same precursor wherein process conditions are altered to provide films of differing dielectric constants. Most preferably, a dual damascene structure has a tri-layer hardmask comprising silicon carbide, PECVD silicon nitride, and PECVD silicon dioxide, respectively, formed over a bulk low dielectric constant interlevel dielectric prior to forming the interconnect structures in the interlevel dielectric. The protective hardmask 40 has a low dielectric constant k which may be the same or similar to that of the bulk dielectric layer 30.

Abstract: A magnetic storage medium is composed of a non-wettable substrate (10) upon which a transient liquid metal layer (18) is deposited and maintained as a distribution of discontinuous liquid features. A magnetic film layer (14) is deposited on the transient liquid metal layer (18) resulting in a reaction of the liquid metal with the magnetic film. The topology of the magnetic film is controllable by adjusting the thickness of the transient liquid metal layer (18).

Abstract: A filter includes a membrane having a plurality of nanochannels (14) formed therein. A first surface charge material (18) is deposited on an end portion of the nanochannels. The first surface charge material includes a surface charge to electrostatically influence ions in an electrolytic solution (20) such that the nanochannels reflect ions back into the electrolytic solution while passing a fluid of the electrolytic solution. Methods for making and using the filter are also provided.

Abstract: DISCLOSED IS VAPOR DEPOSITED THICK ARC LAYER AND METHOD OF PREPARING SINGLE AND TUNABLE THICK BOTTOM LAYER COATINGS BASED ON AMORPHOUS CARBON FILMS. THESE FILM CAN BE HYDROGENATED, FLUORINATED, NITROGENATED CARBON FILMS. SUCH FILMS HAVE THE INDEX OF REFRACTION AND THE EXTINCTION COEFFICIENT TUNABLE FROM ABOUT 1.4 TO ABOUT 2.1 AND FROM ABOUT 0.1 TO 0.6, RESPECTIVELY, AT UV AND DUV WAVELENGHTS, IN PARTICULAR 365, 248 AND 193 NM. THIS MAKES THE FILMS EXTREMELY USEFUL TO BE USED AS THICK BOTTOM LAYERS IN A BILAYER RESIST SYSTEM. MOREOVER, THE FILMS PRODUCED BY THE PRESENT INVENTION CAN BE DEPOSITED OVER DEVICE TOPOGRAPHY WITH HIGH CONFORMALITY, AND THEY ARE ETCHABLE BY OXYGEN AND/OR FLUORINE ION ETCH PROCESS. BECAUSE OF THESE UNIQUE PROPERTIES, THESE FILMS CAN BE USED TO FORM A SINGLE OR TUNABLE THICK BOTTOM LAYER AT UV AND DUV WAVELENGHTS TO PRODUCE PRACTICALLY ZERO REFLECTIONS AT THE RESIST/BOTTOM LAYER INTERFACE. THIS GREATLY IMPROVES PERFORMANCES OF SEMICONDUCTORS CHIPS.

Abstract: A micro-electromechanical (MEM) RF switch provided with a deflectable membrane ( 60 ) activates a switch contact or plunger ( 40 ). The membrane incorporates interdigitated metal electrodes ( 70 ) which cause a stress gradient in the membrane when activated by way of a DC electric field. The stress gradient results in a predictable bending or displacement of the membrane ( 60 ), and is used to mechanically displace the switch contact ( 30 ). An RF gap area ( 25 ) located within the cavity ( 250 ) is totally segregated from the gaps ( 71 ) between the interdigitated metal electrodes ( 70 ). The membrane is electrostatically displaced in two opposing directions, thereby aiding to activate and deactivate the switch. The micro-electromechanical switch includes: a cavity ( 250 ); at least one conductive path ( 20 ) integral to a first surface bordering the cavity; a flexible membrane ( 60 ) parallel to the first surface bordering the cavity ( 250 ), the flexible membrane ( 60 ) having a plurality of actuating electrodes ( 70 ); and a plunger ( 40 ) attached to the flexible membrane ( 60 ) in a direction away from the actuating electrodes ( 70 ), the plunger ( 40 ) having a conductive surface that makes electric contact with the conductive paths, opening and closing the switch.
