摘要:
A CVD (chemical vapor deposition) reactor is disclosed to include a reaction chamber, a gas heater, a substrate holder, a substrate heater, hot filaments, an electric field generator, and a magnetic field generator. By means of preheating applied gas with the gas heater and heating the substrate with the substrate holder and the hot filaments, the gas and substrate heating speed is accelerated, thereby saving much deposition time and greatly improving deposition efficiency. Matching with the electric field generator and the magnetic field generator, the ionization of applied gas in the reaction chamber is enhanced and, the uniformity of the thickness of deposition of metal substance on the surface of the substrate(s) is increased.

A diamond substrate and a method for fabricating the same are provided, wherein a protection layer is formed on one surface of a diamond layer in the process of forming the diamond layer by chemical vapor deposition process, for reducing the deformation of the diamond layer. Thereby the deformation of diamond substrate falls within the range of permitted tolerance of deformation, so that the performance of the diamond substrate is enhanced.

A memory module structure of the invention is used for being assembled on a locking device. The memory module includes a substrate and a plurality of memories. The substrate has certain long sides and short sides. Notches are formed on the short sides for being secured by the locking device. Each of the plurality of memories has a suitable length and width. Some memories of the plurality of memories are transversely mounted on the substrate with respect to the substrate. The other memories of the plurality of memories are longitudinally mounted on the substrate with respect to the substrate. According to this structure, it is possible to suitably arrange a plurality of memories on the substrate so as to increase the memory capacity of the memory module.
摘要:
A method for fabricating a diamond diaphragm is provided, wherein a non-homogeneous energy, generated by a hot wire, plasma, or flame, for activating and dissociating gas is provided to pass above a mold. Due to different distances between a curved surface of the mold and the non-homogeneous energy, different heating effects are produced on the surface of the mold. When the diamond material is coated and grows on the surface of the mold, the growth rate of the diamond material appears to be different by location, thus, the diamond diaphragm has a non-homogeneous vibration characteristic, and thereby having a response bandwidth wider than that of a diamond diaphragm with homogeneous vibration characteristic.
