摘要:
A thin film forming apparatus using laser includes a chamber (1), a target (5) placed therein, a laser light source (10) for emitting laser beam to target (5), and a substrate holder (3). When target (5) is irradiated with laser beam (16), a plume (15) is generated, and materials included in plume (15) are deposited on the surface of a substrate (2) held by substrate holder (3). The laser beam emitted from laser light source (10) has its cross section shaped to a desired shape when passed through a shielding plate (4804), for example, so that the surface of the target (5) is irradiated with the beam having uniform light intensity distribution. Therefore, a plume (15) having uniform density distribution of active particles is generated, and therefore a thin film of high quality can be formed over a wide area with uniform film quality, without damaging the substrate.

A thin film forming apparatus using a laser includes a chamber (1), a target (5) placed therein, a laser light source (10) for emitting a laser beam to target 5, and a substrate holder (3). When the target is irradiated with a laser beam, a plume (15) is generated, and materials included in plume 15 are deposited on the surface of a substrate (2) held by the substrate holder (3). A magnetic field is generated to direct the plume. The magnetic field can be parallel to the surface of the substrate or in another embodiment a cusp magnetic field can be used (see FIG. 130).

A chemical vapor deposition (CVD) apparatus for depositing a thin film on a substrate by CVD has a material container for containing a liquid CVD source material, a material feeder for feeding the liquid CVD source material to a vaporizer for vaporizing the liquid CVD source material, and a reaction chamber for forming the thin film on the substrate using the CVD source material gas. Both the vaporizer and piping between the vaporizer and the reaction chamber are located in a thermostatic box surrounding the reaction chamber. Thus, the structure of the apparatus is simplified and also the heat efficiency of the apparatus is improved.
摘要:
The present invention relates to a microchannel chip capable of preventing fluid leakage caused by a lamination defect. Bottomed first regions, second regions, and third regions are formed by joining a film to a lower surface of the chip main body of a microchannel chip. The third regions are in communication with the second regions and are formed on carbon inks. The third regions are formed wider than the carbon inks are. The third regions are filled with an electroconductive adhesive.

A folding circuit and an analog-to-digital converter wherein a response to small signals is improved, a load on a clock signal can be reduced, and the increase of circuit area can be prevented. The circuit includes a reference voltage generating circuit that generates a plurality of differential voltages as reference voltages, and a plurality of amplification circuits that convert differential voltages between the plurality of reference voltages and an analog input voltage to differential currents, and output these differential currents. The output ends of the amplification circuits are alternately connected.

A first liquid fed into a first flow passage 6 of a fluid handling apparatus travels to the open end thereof on the side of a second flow passage 7 due to capillarity. The movement of the first liquid is uniformed on the cross section of the flow passage by the function of a capillarity promoting portion 220 or 230 of the bottom 21 of the first flow passage 6. Then, the movement of a second liquid fed into the second flow passage 7 is uniformed on the cross section of the flow passage by the function of the capillarity promoting portion 220 or 230 of the bottom 21 of the second flow passage 7. Thus, the movement of the front end of the second liquid is substantially uniformed to surely extrude gas from the second flow passage 7 to the outside via a fourth flow passage 10.
