The present invention concerns thin diffusion barriers in metal and metal alloy layer sequences of contact area/barrier layer/first bonding layer type for metal wire bonding applications. The diffusion barrier is selected from Co-M-P. Co-M-B and Co-M-B&#x2014;P alloys wherein M is selected from Mn, Zr, Re, Mo, Ta and W having a thickness in the range 0.03 to 0.3 &#x3bc;m. The first bonding layer is selected from palladium and palladium alloys.

Wire bondable surface for microelectronic devices

The invention relates to a substrate having a bondable metal coating comprising, in this order, on an Al or Cu surface: (a) a Ni&#x2014;P layer, (b) a Pd layer and, optionally, (c) an Au layer, wherein the thickness of the Ni&#x2014;P layer (a) is 0.2 to 10 m, the thickness of the Pd layer (b) is 0.05 to 1.0 m and the thickness of the optional Au layer (c) is 0.01 to 0.5 m, and wherein the Ni&#x2014;P layer (a) has a P content of 10.5 to 14 wt.-%. The deposit internal stress of the resulting Ni&#x2014;P/Pd stack is not higher than 34.48M&#x2212;Pa (5,000 psi). Further, a process for the preparation of such a substrate is described.

A substrate for inkjet printing, which includes a photoresist layer structure on a base substrate, and a method of manufacturing the same are provided. The substrate, which has high surface tension variation and slight thickness variation, may be manufactured at a low cost. The substrate includes a discontinuous organic layer structure made of a fluorinated hydrocarbon or a polysiloxane on the photoresist layer structure.

Substrate for inkjet printing and method of manufacturing the same

A flat panel display and a method of manufacturing the same, which allows the formation of an organic film by inkjet printing while avoiding overflow of ink into adjacent areas, thus increasing the uniformity of thickness of the organic film and decreasing manufacturing costs. The flat panel display includes a substrate, a first electrode layer formed on the substrate, ink with material for a light emission layer formed on an active area of the first electrode layer, a repellant area formed of organic material located around the active area, and a border area also formed of organic material located between the active area and the repellant area. A surface energy of the border area is higher than a surface energy of the repellant area.

A substrate for a light-emitting element based on an organic light-emitting material and a method of manufacturing the same are provided. The substrate can be manufactured at low cost and has long lifespan, and an organic material used on the substrate and has high electrical conductivity. The substrate for a light-emitting element includes a base substrate with metal layer formed on the base substrate and a conductive polymer layer disposed on the metal layer.

Substrate for light-emitting element, method for manufacturing the same, electrode for light-emitting element, and light-emitting element having the same

An organic light-emitting diode (OLED) with an increased service life and a method of manufacturing the same are provided. The OLED is subjected to electromagnetic radiation with a spectrum that at least partially overlaps the absorption spectrum of an organic material layer of the OLED. As a result, the OLED has a longer service life, reduced decay in its initial brightness, and more saturated color than a conventional OLED.

Organic light-emitting diode and method of manufacturing the same

An organic light emitting device (OLED) comprising an anode, an organic emissive layer, a cathode, and an ion-complexing material layer, and a display using the OLED, are provided. The ion-complexing material layer is arranged between the anode and the cathode.

A flat display device and a method of manufacturing the same are disclosed. The flat panel display includes first electrode layers and second electrode layers arranged on top of a substrate. Multiple pixel regions, arranged between the first electrode layer and the second electrode layer, are formed by a light-emitting portion which includes light-emitting layers. Barriers are formed with at least one or more layers at least partially between the pixel regions, and a groove portion is formed at least partially on one side of each barrier.

Flat display device including an overflow barrier

An organic light emitting diode (OLED) includes a substrate having a first electrode layer formed thereon in a predetermined pattern, an insulator layer defining the upper portion of the substrate having the first electrode layer in a predetermined pattern, an organic polymer layer formed based on the pattern defined by the insulator layer, a barrier for blocking flow of the organic polymer layer at both ends of the pattern defined by the insulator layer, and a second electrode layer formed on the organic polymer layer.

Organic light emitting diode and method for producing the same

A shadow mask for a color picture tube a thermal includes insulating layer preventing heat transfer to an apertured shadow mask. The side of the mask directed toward the cathode of the color picture tube is coated with a heat-insulating layer including particles having a porous structure. The pores may contain heavy metals or heavy metal compounds so that electron reflection and absorption occurs directly within the layer. The resulting heat is transferred to the interior of the picture tube instead of to the mask.

Shadow mask having an insulating layer and a process for the production

A process is provided for the electrochemical analysis of compounds of solutions, such as can, e.g., be used in chemical analysis or for control measurements in industrial and environmental sectors. Identification or detection of individual substances takes place by the deposition thereof on electrodes and subsequent detection of the deposited substances. In the process, use is made of a plurality of electrodes. The substances to be identified from the solution are so simultaneously deposited on the electrodes that each electrode is coated with a different substance or substance mixture. Then, the deposited substances are simultaneously identified on the individual electrodes. Thus, the measuring time is significantly shortened and the risk of faulty measurements due to interactions between the substances to be identified on the electrodes is significantly reduced.
