Fabrication of lean-free stacked capacitors

For fabricating lean-free stacked capacitors, openings are formed through layers of materials including a layer of support material displaced from a bottom of the openings. A respective first electrode is formed for a respective capacitor within each of the openings. The layer of support material is patterned to form support structures around the first electrodes. Masking spacers are formed around exposed top portions of the first electrodes, and exposed portions of the support material are etched away to form the support structures. Such stacked capacitors are applied within a DRAM (dynamic random access memory).

Electroluminescent device

The invention relates to a matrix of electroluminescent organic material having quantum dots embedded therein. Electrodes provide electrons and holes to the matrix forming excitons to be transferred to the quantum dots. The invention provides transfer molecules on the quantum dots facilitating the transfer of excitons from the electroluminescent organic material to the quantum dots, by first transferring them to the transfer molecules. The transfer molecules are chosen to make a transfer rate of excitons from the organic material to the transfer molecules larger than a decay rate of excitons in the organic material. More specifically, the organic matrix forms a light emitting layer in a light emitting device (LED). Also, the electroluminescent organic material is preferably an electroluminescent polymer.

Electrically active polymer compositions and their use in efficient, low operating voltage, polymer light-emitting diodes with air-stable cathodes

The addition of a highly polarizable additive such as an organic anionic surfactant to an electrically active polymer improves the electrical properties of the polymer. When such an additive is added to an electroluminescent organic polymer this mixture can be used in diodes having an anode contacting a layer of this mixture as the active light-emitting layer and an air-stable metal cathode having a work function larger than 4 eV. The external efficiency and brightness versus voltage are significantly improved compared to results obtained with the same electroluminescent polymer used alone with high work function (>4.0 eV) metal cathodes. Specifically, device performance with indium / tin-oxide (ITO) as the anode, poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene), MEH-PPV, as the electroluminescent polymer, lithium nonylphenoxy ether sulfate as the surfactant additive and aluminum as the cathode is comparable to or better than that obtained with high performance devices using calcium as the cathode.

Magnetic tunnel junction patterning using Ta/TaN as hard mask

An MTJ MRAM cell is formed by using a reactive ion etch (RIE) to pattern an MTJ stack on which there has been formed a bilayer Ta / TaN hard mask. The hard mask is formed by patterning a masking layer that has been formed by depositing a layer of TaN over a layer of Ta on the MTJ stack. After the stack is patterned, the TaN layer serves at least two advantageous purposes: 1) it protects the Ta layer from oxidation during the etching of the stack and 2) it serves as a surface having excellent adhesion properties for a subsequently deposited dielectric layer.
