The present disclosure relates, according to some embodiments, to a data writing method in a storage system.

The idea of the invention is to coat the free surface of patterned Cu conducting lines in on-chip interconnections (BEOL) wiring by a 1-20 nm thick metal layer prior to deposition of the interlevel dielectric. This coating is sufficiently thin so as to obviate the need for additional planarization by polishing, while providing protection against oxidation and surface, or interface, diffusion of Cu which has been identified by the inventors as the leading contributor to metal line failure by electromigration and thermal stress voiding. Also, the metal layer increases the adhesion strength between the Cu and dielectric so as to further increase lifetime and facilitate process yield. The free surface is a direct result of the CMP (chemical mechanical polishing) in a damascene process or in a dry etching process by which Cu wiring is patterned. It is proposed that the metal capping layer be deposited by a selective process onto the Cu to minimize further processing. We have used electroless metal coatings, such as CoWP, CoSnP and Pd, to illustrate significant reliability benefits, although chemical vapor deposition (CVD) of metals or metal forming compounds can be employed.

A display device includes an integrated liquid crystal display and a backlight unit. The liquid crystal display is provided with a backlight system that includes a light-emitting element positioned along one or more sides of the display.

For shielding, the backlight cover can separate the display from an electronic circuit assembly. The backlight cover may be made monolithically of a heat-conductive material such as aluminum, as well as an electro-conductive material for shielding. The backlight cover may also provide mechanical support for the display device and mounting features to ease assembly and mounting to a target location. Such a display device may be deployed on a vehicle, for instance, as part of a vehicle navigation, communication, and / or entertainment system.
