A process for producing a capacitive electromechanical conversion device by bonding together a substrate and a membrane member to form a cavity sealed between the substrate and the membrane member, the process for producing a capacitive electromechanical conversion device comprises the steps of: providing a gas release path penetrating from a bonded interface between the substrate and the membrane member to the outside, and forming the cavity by bonding the membrane member with the substrate with the gas release path provided; the gas release path being provided at a location where the path does not communicate with the cavity.

A thin film transistor (TFT) array panel structure and a fabrication method thereof are provided. The method includes the following steps. An insulating substrate is provided, on which a first metal layer is deposited to form a plurality of gate electrodes, a plurality of lower electrodes of storage capacitors, a plurality of scan lines, and a plurality of scan line pads with a first mask process. A TFT island region is formed with a second mask process. Drain electrodes and source electrodes of the TFT, upper electrodes of storage capacitors, pixel electrodes, data lines and data line pads are formed, and a plurality of pixel display regions is defined with a third mask process. The pattern of a passivation layer is defined with a fourth mask. A second metal layer in the pixel display region is removed by selective etching.

A range of carbon materials can be produced using lignin in combination with synthetic phenolic resins or naturally occurring lingo-cellulosic materials. The lignin, which is essentially a naturally occurring phenolic resin, has a carbon yield on pyrolysis similar to that of the synthetic resins, which aids processing. The lignin can be used as a binder phase for synthetic resin or lignocellulosic materials allowing the production of monolithic carbons from a wide range of precursors, as the primary structural material where the thermal processing is modified by the addition of small quantities of synthetic resin materials or as structure modified in the production of meso / macro porous carbons in either bead, granular or monolithic form. A carbonised monolith is provided comprising mesoporous and / or macroporous carbon particles dispersed in a matrix of microporous carbon particles with voids between the particles defining paths for fluid to flow into and through the structure. The monolith may take the form of a shaped body having walls defining a multiplicity of internal transport channels for fluid flow, the transport channels being directed along the extrusion direction. The monolith may be made by carbonising a shaped phenolic body based on phenolic resin precursors. In a method for producing such a carbonisable shaped resin body solid particles of a first phenolic resin are provided which is partially cured so that the particles are sinterable but do not melt on carbonisation. The particles of the first phenolic resin are mixed with particles of a second phenolic resin that has a greater degree of cure than said first phenolic resin and has a mesoporous and / or macroporous microstructure that is preserved on carbonisation. The resulting mixture is formed into a dough e.g. by mixing the resin particles with methyl cellulose, PEO and water, after which the dough is extruded to form a shaped product and stabilising in its shape by sintering.
