    Abstract: PURPOSE:To perform processing of increased elaborateness and good reproducibility in processing part of an organic polymer, by selectively irradiating the area to be processed with laser beams and removing organic polymer on an unirradiated area by heating or etching. CONSTITUTION:In processing pattof an organic polymer, an organic polymer on an area to be processed is irradiated selectively with laser beams. Then an organic polymer on an unirradiated area is removed by heating or etching. It is desirable that an excimer laser is used as said laser beams. When polytetrafluoroethylene or thermosetting 1,2-polybutadiene resin is used as said organic polymer, said processing is highly effective because such resins can hardly be processed otherwise.

    Abstract: PROBLEM TO BE SOLVED: To implement field emission at a low voltage by making close a distance between a gate and an emitter with the center of an emitter electrode portion having a more recessed shape than its periphery. SOLUTION: A recessed portion having a depth of 0.5-0.3 μm is formed by etching at a cathode wiring 2 portion of a substrate having an insulation characteristic at its surface and being made of glass or the like, then an Mo is formed by sputtering, and patterning is performed, thereby forming a cathode wiring 2. Nextly, an interlayer insulation film 6 for performing insulation between the wiring 2 and gate wiring 8 is formed of SiO2, or the like with a thickness of about 800 nm, and thereon the wiring 8 is applied with pattering of Ni with a thickness of 1 μm by electroless plating of Ni-P type. Then, the wiring 2 is exposed by etching the film 6 of an emmitter formation part, dispersion liquid having ethanol as dispersant while containing CBN fine particles is dropped thereon so that the surface is made recessed. Thereafter, after a solvent is volatiled, thermal treatment is applied thereto to fix the Mo and CBN of the wiring 2 to use is as an eanitter, which is made close to the wiring 8.

    Abstract: PROBLEM TO BE SOLVED: To provide an environment influence evaluation table assuming/evaluating influence given to an environment from harmfulness and usefulness when technology to be researched is completed, and to provide a computer system for generating the evaluation table and outputting an evaluation result using the evaluation table. SOLUTION: This table has a column for evaluating an evaluation result with respect to a plurality of evaluation items on harmfulness and usefulness when development completes, an entry column for a point obtained by multiplying the evaluation value and the weight points of the respective items, a total column into which the total of the points of the respective items is filled, a column which judges the total number of the evaluation result and into which 'significance' or 'no' is written, the content filling column of 'presence' against harmfulness or usefulness and a progress report column. This evaluation system has information 32 on the evaluation item and information 33 of evaluation reference. A generation supporting means 41 generates evaluation information 31 of research/development technology where a generation supporting means 41 becomes object based on information. An evaluation means 42 automatically executes evaluation on generated evaluation information 31 and the result is added to evaluation information 31. Evaluation information is outputted in the environment influence evaluation table and in the other system.
