Substrate processing apparatus

A substrate processing apparatus stably and efficiently conducts a film forming process on a substrate to be processed. In the substrate processing apparatus, the substrate to be processed is supported at a position facing a heater portion, and a holding member for holding the substrate is rotated, whereby the temperature distribution of the substrate is kept uniform and a warp of the substrate is suppressed. The inner wall of the processing vessel is covered with a quartz liner which is made of opaque quartz, and thus protected from ultraviolet rays emitted from an ultraviolet light source. The temperature rise of the inner wall caused by heat from the heater portion is suppressed due to the heat insulating effect of the quartz liner. Consequently, the life cycle of the processing vessel can be prolonged.

Semiconductor integrated circuit device and manufacturing method thereof

A manufacturing process for a semiconductor integrated circuit device which prevents occurrence of reaction between metal wiring and a boron-doped silicon plug over it in heat treatment for a MOS transistor to be formed over them and reduces the possibility of rise in contact resistance. Metal boride is formed on an exposed metal surface in the bottom of an opening made in an interlayer insulating film over the metal wiring. In order to facilitate formation of such metal boride, metal oxide remaining on the metal surface is removed with an aqueous ammonia solution. The meal surface is irradiated with high energy ultraviolet light in order to remove organic matter remaining in the opening and facilitate removal of the metal oxide with the aqueous ammonia solution.

Photopolymerizable biodegradable hydrogels as tissue contacting materials and controlled-release carriers

Hydrogels of polymerized and crosslinked macromers comprising hydrophilic oligomers having biodegradable monomeric or oligomeric extensions, which biodegradable extensions are terminated on free ends with end cap monomers or oligomers capable of polymerization and cross linking are described. The hydrophilic core itself may be degradable, thus combining the core and extension functions. Macromers are polymerized using free radical initiators under the influence of long wavelength ultraviolet light, visible light excitation or thermal energy. Biodegradation occurs at the linkages within the extension oligomers and results in fragments which are non-toxic and easily removed from the body. Preferred applications for the hydrogels include prevention of adhesion formation after surgical procedures, controlled release of drugs and other bioactive species, temporary protection or separation of tissue surfaces, adhering of sealing tissues together, and preventing the attachment of cells to tissue surfaces.
