A dual resistance heater for a phase change material region is formed by depositing a resistive material. The heater material is then exposed to an implantation or plasma which increases the resistance of the surface of the heater material relative to the remainder of the heater material. As a result, the portion of the heater material approximate to the phase change material region is a highly effective heater because of its high resistance, but the bulk of the heater material is not as resistive and, thus, does not increase the voltage drop and the current usage of the device.

Several techniques are described for reducing or mitigating the formation of seams and/or voids in electroplating the interior regions of microscopic recessed features. Cathodic polarization is used to mitigate the deleterious effects of introducing a substrate plated with a seed layer into an electroplating solution. Also described are diffusion-controlled electroplating techniques to provide for bottom-up filling of trenches and vias, avoiding thereby sidewalls growing together to create seams/voids. A preliminary plating step is also described that plates a thin film of conductor on the interior surfaces of features leading to adequate electrical conductivity to the feature bottom, facilitating bottom-up filling.

The transparent coating for one or more display areas of a glass or glass-ceramic plate is made by a process using a sol-gel paint containing alkyl silicates as binding agents. The transparent coating is provided on areas of the glass or glass-ceramic plate that have been left uncoated by a color-imparting opaque coating and is formed by applying the sol-gel paint to the areas left open and then thermally treating the sol-gel paint so as to cross-link reactive groups of the alkyl silicates. The coating has organic, non-hydrolyzable groups bound directly to silicon. A process for making the coating and the uses of the coated glass or glass-ceramic plate are part of the invention.

Processes for increasing the chemical resistance of a surface of a formed article are disclosed. The formed article is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a monofunctional benzophenone. The surface of the formed article is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.

We discovered that the use of certain dopants or dopant moieties in polymeric coating formulations, that when applied over carbon nanotubes, unexpectedly decrease the measured electrical resistance of the coated carbon nanotubes (CNTs), when measured through the coating, even though the polymer coatings themselves do not have bulk conductivity. CNT compositions with enhanced electrical conductivity and methods of making such compositions are described. The CNTs are preferably coated with a dopant or dopant moiety having a HOMO energy of −7.0 eV or lower.

The inventive method of improving the lithium ion battery safety is to raise the facial resistance of the anode strip, and to reduce the thermal conductivity of the anode strip, namely to cover a metal oxide material membrane layer on the anode strip surface of the lithium ion battery for raising the facial resistance of the anode strip and reducing the thermal conductivity of the anode strip. Use of the invention can raise the facial resistance of the anode strip, so after of the cathode current collector is in short circuit with the anode diaphragm, the resistance is greater, its current is smaller, resulting in a reduction of the produced, thereby the manufactured battery may easily pass through the short-circuit test, and the safety factor reaches the standard. At the same time the film layer formed by adopting the metal oxide, has a better hole for passing through lithium ions in its material interior structure, without any influence on the electrochemistry performance of the battery. The lithium ion battery that adopts this invention has a higher safety than the safety performance of the ordinary lithium ion battery.

A silicon-on-insulator radio frequency device and a silicon-on-insulator substrate are provided. In the silicon-on-insulator radio frequency device, a pit is formed on a surface of a high resistivity silicon plate which is close to a buried oxide layer. The pit may be filled with an insulating material, thereby increasing an equivalent surface resistance of the high resistivity silicon plate; or no insulating material is filled into the pit, that is, the pit remains a vacuum state or is only filled with air, which can increase the equivalent surface resistance of the high resistivity silicon plate as well. In such, an eddy current generated on a surface of the high resistivity silicon plate under the action of a radio frequency signal may be reduced. As a result, loss of the radio frequency signal is reduced and the linearity of the radio frequency signal is improved.
