DVD-R DL (DL stands for Dual Layer), also called DVD-R9, is a derivative of the DVD-R format standard. DVD-R DL discs hold 8.5 GB by utilizing two recordable dye layers, each capable of storing a little less than the 4.7 gigabyte (GB) of a single layer disc, almost doubling the total disc capacity. Discs can be read in many DVD devices (older units are less compatible) and can only be written using DVD-R DL compatible recorders. It is part of optical disc recording technologies for digital recording to optical disc.

Method for forming a dual layer, low resistance metallization during the formation of a semiconductor device
InactiveUS20060097397A1Reduce the cross-sectional areaHigh resistance contactSemiconductor/solid-state device detailsSolid-state devicesDevice materialCopper
A method for providing a highly reliable, low resistance interconnect comprises forming a trench in a dielectric layer, forming a first liner in the trench then forming a resilient layer such as a tungsten layer within the trench. The resilient layer is etched back to remove the layer from a horizontal portion of the dielectric outside the trench and to recess the layer within the trench. Next, a second liner and a copper layer are formed in the trench over the resilient layer. The copper layer and exposed portions of the two liners are polished or etched back to result in the interconnect. Variations to this embodiment are also described.

Air gap interconnect structure and method of manufacture
A dual layer of polymeric material is deposited with a base layer and top layer resist onto an integrated circuit structure with topography. The base layer planarizes the surface and fills in the native topography. The base layer decomposes almost completely when exposed to an oxidizing environment. The top layer contains a high composition of oxidizing elements and is photosensitive. (i.e., the layer can be patterned by exposing normal lithographic techniques.) The patterning allows the creation of escape paths for the decomposition products of the underlying base layer. This structure is decomposed in an oxidizing ambient (or plasma) leaving behind a thin carbon-containing membrane. This membrane layer blocks deposition of future layers, creating air gaps in the structure.

Metal lithium negative electrode with dual-layer structure
The invention relates to a metal lithium negative electrode with a dual-layer structure. The metal lithium negative electrode comprises a metal lithium layer at a bottom layer and a surface cover layer at an upper layer. In the metal lithium negative electrode, a surface layer structure on the surface can be used for controlling distribution of lithium ions on the surface of the negative electrode, the lithium ions are prevented from being gathered in time and space, and the uniform distribution of the lithium ions on the surface of the negative electrode is achieved, so that dendritic crystal is prevented. The control behavior of the surface layer structure of the metal lithium negative electrode on the lithium ions is achieved by a material having a relatively high absorption effect on the lithium ions. Compared with a metal lithium negative electrode without the dual-layer structure, the metal lithium negative electrode with the dual-layer structure has the advantages that the growth of lithium dendritic crystal can be prevented, the safety of the metal lithium negative electrode can be ensured, the energy utilization ratio of the battery can be relatively and substantially improved, and the cycle lifetime of the battery can be relatively and substantially prolonged. If the metal lithium negative electrode is used with a high-capacity positive electrode material in a matching way, the practical progress of a novel high-energy density lithium battery can be promoted.

Reflective spatial light modulator having dual layer electrodes and method of fabricating same
ActiveUS7477440B1Reduce distanceReduce the possibilityOptical elementsSpatial light modulatorLow voltage
A reflective spatial light modulator device features two pairs of electrodes formed on different metallization layers. Elevation of the upper electrode pair reduces its distance from the overlying reflecting surface, thereby requiring a smaller applied voltage to generate an equivalent electrostatic attractive force for altering or maintaining physical orientation of the reflecting surface relative to incident light. In one embodiment, the reduced distance between the electrode and reflecting surface allows operation at lower voltages, reducing the possibility of breakdown and avoiding the need for complex device designs to eliminate such breakdown. In another embodiment, the reduced distance between the electrode and the reflecting surface allows the use of stiffer hinges for the reflecting surface, thereby increasing the speed of device operation. Other embodiments can employ both reduced voltage operation and the use of stiffer hinge structures.
