Abstract:
A method for planarizing a high step-height integrated circuit structure within an integrated circuit. There is first formed upon a semiconductor substrate a high step-height integrated circuit structure. Formed then adjoining the high step-height integrated circuit structure is a patterned Global Planarization Dielectric (GPD) layer. There is then formed upon the exposed surfaces of the semiconductor substrate, the high step-height integrated circuit structure and the patterned Global Planarization Dielectric (GPD) layer a reflowable dielectric layer. Finally, the reflowable dielectric layer is reflowed.
Abstract:
The present invention is a method of manufacturing crown shape capacitors in the semiconducter memories. Using a single step etching to farbricate the capacitor in a DRAM cell. The method can form side wall polymers and etching byproductions on the surface of the first polysilicon, using the side wall polymers and the etching byproductions as a mask to form the crown shape capacitors with pillars. Moreover, this present invention can form the crown shape structure and pillars in the same step, the crown shape structure and the pillars increase the surface area of the capacitor. Therefore the present invention will increase the performance of the capacitor.
Abstract:
A method for manufacturing a stacked capacitor having fin-shaped electrodes with increased capacitance on a dynamic random access memory (DRAM) cell, was achieved. The invention eliminates the need for a silicon nitride etch stop layer, which is known to cause stress in the substrate and lead to defects. The capacitor bottom electrodes having fin shaped portions is fabricated by depositing a multilayer of alternate layers of silicon oxide and doped polysilicon on a partially completed DRAM device having FETs. After forming, with single masking step, the node contacts to the substrate in the multilayer and depositing another doped polysilicon layer, the polysilicon layers and oxide layer are patterned to form the electrodes. An important feature of this invention is that the patterned multilayer is etched to the silicon oxide layer over the bottom polysilicon layer and then the silicon oxide layer(s) are isotropically etched (e.g. in HF) to form the fin capacitor. The fin structure is then used as a mask to anisotropically etch the bottom polysilicon layer, and thereby complete and electrically isolate the bottom fin-shaped electrodes. The capacitor is completed by forming the inter-electrode dielectric and depositing a top electrode layer.

Abstract:
Flavonoid compounds may be prepared that are selective for certain cell organelles, and may be used as biological imaging agents. Organelles that may be imaged with flavonoid compounds include mitochondria and lysosomes. Advantageously, the flavonoids show specificity to certain organelles and may exhibit a florescence “turn-on” mechanism, where the flavonoids that have target an organelle exhibit a florescence response when excited.
Abstract:
Semiconductor devices are provided including an active layer, a gate structure, a spacer, and a source/drain layer. The active layer is on the substrate and includes germanium. The active layer includes a first region having a first germanium concentration, and a second region on both sides of the first region. The second region has a top surface getting higher from a first portion of the second region adjacent to the first region toward a second portion of the second region far from the first region, and has a second germanium concentration less than the first germanium concentration. The gate structure is formed on the first region of the active layer. The spacer is formed on the second region of the active layer, and contacts a sidewall of the gate structure. The source/drain layer is adjacent to the second region of the active layer.

A vehicle shading apparatus may include a first front shading control unit, a first rear shading control unit, a second top shading control unit, and a second rear shading control unit. In one embodiment, one end of the first top shading control unit is connected to the second top shading control unit. One end of the first rear shading control unit and a horizontal supporting unit are connected to the second rear shading control unit. The second top shading control unit and second rear shading control unit both include a shading cloth extending along the body of the vehicle. The present invention is advantageous because it has an automatic shading cloth expand/restore control unit and high-strength supporting unit. It is portable, easy to install and has the shading all around the vehicle to effectively block the sunlight.
Abstract:
Methods, compositions and articles of manufacture involving soluble conjugated polymers are provided. The conjugated polymers have a sufficient density of polar substituents to render them soluble in a polar medium, for example water and/or methanol. The conjugated polymer may desirably comprise monomers which alter its conductivity properties. In some embodiments, the inventors have provided cationic conjugated polymers (CCPs) comprising both solubilizing groups and conductive groups, resulting in conductive conjugated polymers soluble in polar media. The different solubility properties of these polymers allow their deposition in solution in multilayer formats with other conjugated polymers. Also provided are articles of manufacture comprising multiple layers of conjugated polymers having differing solubility characteristics. Embodiments of the invention are described further herein.

Methods, compositions and articles of manufacture for assaying a sample for a target polynucleotide are provided. A sample suspected of containing the target polynucleotide is contacted with a polycationic multichromophore and a sensor PBP that can bind to the target polynucleotide. The sensor PBP comprises a signaling chromophore to absorb energy from the excited multichromophore and emit light in the presence of the target polynucleotide. The methods can be used in multiplex form. Kits comprising reagents for performing such methods are also provided.

An exemplary electronic device is connected with an earphone. The earphone includes a first storage unit storing information as to functions of the earphone. The electronic device includes a second storage unit storing a function information table recording information as to user-controllable functions of the electronic device, function units corresponding to the user-controllable functions, an identifying module, and a control module. The identifying module retrieves the information as to functions stored in the first storage unit, and determines whether one or more of the controllable functions of the electronic device are controllable by the earphone. The control module activates all of the function units corresponding to the controllable functions of the electronic device which are controllable by the earphone, and controls one or more of the activated function units according to one or more control signals transmitted from the earphone to the electronic device.
