    摘要: A method of monitoring loss of silicon nitride, used to monitor the loss of a first etch stop layer below a first insulating layer in a first contact opening opening after the first contact opening is formed in the first insulating layer over a device region and scribe line of a wafer. A dummy wafer is provided on which stacks in sequence a second etch stop layer and a second insulating layer. The second insulating layer is patterned by removing a portion of the second insulating layer, so that a monitoring opening that exposes the second etch stop layer and a second contact opening are formed in the second insulating layer. A first measuring step is performed to measure a first thickness loss and a second thickness loss from the second etch stop layer exposed respectively by the monitoring opening and the second contact opening on the dummy wafer. And a correlation is established from the first and second thickness losses. A second measuring step is performed to measure a third thickness loss from the first etch stop layer exposed by the monitoring opening on the wafer. The result is then compared with the correlation to deduce a fourth thickness loss from the first contact opening on the wafer.

    摘要: A method of forming a local interconnect contact opening is described. A liner layer is formed on a substrate having a gate structure, a first source/drain region, and a second source/drain region formed thereon. A planarized dielectric layer is formed over the liner layer. A photoresist layer, which defines the location of the local interconnect contact opening, is formed over the dielectric layer. A one-step etching process is performed using a C5F8/CO/O2/Ar etching gas and the liner layer as an etching stop. The dielectric layer exposed by the opening of the photoresist layer is removed to expose the liner layer. The liner layer and the photoresist layer are removed.

    摘要: Oxygen from water can be efficiently and economically achieved via water electrolysis on antimony, nickel doped tin oxide (Sb,Ni—SnO2/Ti) anode using low DC power. As O2 is evolved, it will be quickly reduced by adjacent cobalt oxide doped carbon nanofilm (Co3O4—CNF/Ti) to hydrogen peroxide (H2O2) and electricity. In the said electricity generation, O2 is first formed in O2 evolution reaction (OER), then, electricity is generated in O2 reduction reaction (ORR). Both of anode and cathode are shared by OER and ORR, yet, the former consumes energy and the latter yields electricity. It is the cathode, a load and the anode that form an electricity-forming circuit. The said circuit relies on clean water to supply the fuel, O2, hence, it is designated as all-water fuel cell (AWFC). Supercapacitor is employed as the load for AWFC, and onboard purifiers are providers of clean water for AWFC.

    摘要: A method for fabricating cylindrical and prismatic rechargeable metal-air batteries is devised. The method includes using micro fans to control air flowing through the batteries via air pathways between the packs of electrodes and separator sheet. The air pathways are created by protrusions printed or molded on plastic spacer film. The air is used by the positive electrode for generating electricity when the metal-air battery is discharged. By conjunction of a second positive electrode and an energy storage device, the micro fans can be actuated as soon as the metal-air battery is demanded by a load. The in-cell air management can not only supply air for reactions but also shut the system to preserve materials when they are not in service.

A conductive line and a patterned anti-reflection coating layer are sequentially formed on the substrate wherein the patterned anti-reflection coating layer has a smaller width than the conductive line and a portion of the conductive layer is exposed by the patterned anti-reflection coating layer. A planarized dielectric layer is formed over the substrate to cover the patterned anti-reflection coating layer and the conductive line. A via hole is formed in the planarized dielectric layer to expose portions of surface and sidewalls of the patterned anti-reflection coating layer as well as the conductive line.

    摘要: The present invention pertains to a via-first dual damascene process. A semiconductor substrate having a conductive structure and a dielectric layer on the semiconductor substrate is provided. The dielectric layer has a via opening exposing the conductive structure. The via opening is filled with a gap-filling polymer to form a gap-filling polymer (GFP) layer on the dielectric layer. The GFP layer is etched back to a predetermined depth such that an exposed surface of the GFP layer is lower than surface of the dielectric layer to form a recess, thereby exposing portions of sidewalls of the via opening. A surface treatment for altering surface property of the sidewalls and the exposed surface of the GFP layer is then carried out, thereby preventing a subsequent deep UV photoresist from interacting with the sidewalls or the exposed surface of the GFP layer either in a chemical or physical way.
