摘要:
A thin, flat, and porous carbon gas diffusion electrode having a side in contact with a supply of gas and a side in contact with an electrolyte, comprises a pyrolysis product of a composite of an organic aerogel or xerogel and a reinforcing skeleton consisting at least in part of organic material. The porosity of the carbon gas diffusion electrode according to the invention can be regulated at will while the surface of the electrode is smooth.

Plasma encapsulation for electronic and microelectronic components such as OLEDs. The invention relates to a plasma encapsulation for electronic and microelectronic components such as OLEDs. However, a conventional standard plasma coating process is not used; instead, an especially gentle plasma coating process which does not cause any damage to sensitive components such as an OLED is used, such as the pulsed method or the “remote” or “after glow method.”
摘要:
Discharging the reaction water from the novel PEM fuel cells does not require humidification of the reaction gases or an increase in the gas pressure. This is attained in that a hydrophobic layer on the cathode side is used which has a smaller pore size than the layer on the anode side. The reaction water is removed via the anode during the operation of the fuel cell.

A gas diffusion electrode made of carbon, a process for producing an electrode and a carbonizable composite are provided. Thin, flat, porous gas diffusion electrodes made of carbon, which have a smooth surface and in which the porosity can be regulated at will, are obtained by pyrolysis of a composite of an organic polymer having a spatial globular structure (SGS polymer) and a reinforcing skeleton formed at least in part of organic material.

Various illustrative embodiments of methods for manufacturing a semiconductor device are described. These methods may include, for example, forming a first polysilicon layer above a substrate, wherein the first polysilicon layer comprises a doped portion, and forming a second polysilicon layer over a surface of the first polysilicon layer. Also, various illustrative embodiments of semiconductor devices are described that may be manufactured such as by the various methods described herein.
摘要:
The prevention of active area loss in the STI model is disclosed which results in an improved device performance in devices manufactured according to the process flow. The process generally shared among the multiple various embodiments inverts the current conventional STI structure towards a process flow where an insulator is patterned with tapered trenches. A segregation layer is formed beneath the surface of the insulator in the tapered trenches. The tapered trenches are then filled with a semiconductor material which is further processed to create a number of active devices. Therefore, the active devices are created in patterned dielectric instead of the STI being created in the semiconductor substrate of the active devices.
