Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite structure comprising a plurality of materials having different functions, for example, a conductive material and an insulating material, a conductive material and a resistive material, and a transparent material and an opaque material. It relates to a method for producing a body.

[0002]

2. Description of the Related Art As a composite structure of a plurality of kinds of substances having different functions, for example, a wiring board using a conductive substance and an insulating substance, for example, a heating element using a conductive substance and a resistive substance There are a wide variety of structures using transparent and opaque materials, such as optical filters or shaped objects.

[0003]

The inner wiring board of the above-mentioned composite structure includes a wiring board called a so-called printed board in which a conductive substance is formed in a predetermined pattern by printing or plating on an insulating board, or an insulating board. There is a ceramic wiring board obtained by printing conductive ink in a predetermined pattern on a conductive ceramic. In order to make the conductive patterns formed on the front and back of the wiring board conductive, an electroless plating method is applied to the printed circuit board, and a method of sintering after filling the conductive ink with the ceramic wiring board is adopted. . Further, among the heat generating elements in the composite structure, there is a device called a thermal head which converts an electric signal into a heat signal for performing printing or the like, and a thermal head is formed by vapor deposition or sputtering. There are a thin film type and a thick film type formed by printing. Among them, a method of manufacturing a thin-film thermal head is to apply a photoresist on an insulating substrate such as aluminum oxide, and then expose and develop the photoresist through a predetermined mask to form a pattern of the photoresist. And a resistive component such as iron, nickel, or chromium is sputtered through the pattern to obtain a resistive thin film.
After removing the electrodes, the patterns of the common electrode and the individual electrodes are formed by photoresist, and then a conductive material such as gold is formed into a film by a method such as vapor deposition.

In addition, a method of manufacturing a thick film type thermal head is to screen an ink containing an organometallic resistive substance and an ink containing a conductive substance by screen printing on an insulating substrate such as aluminum oxide. It is formed by printing on a predetermined pattern, removing the organic components in the ink by heat treatment, and then filling the gap with the pattern and an insulating material as a protective film by sputtering or the like. Each of these wiring boards or heating elements is a technology of forming a pattern of a conductive substance or a resistive substance on an insulating substance. Therefore, a thin film type requires a photomask process, and the photomask process requires mask alignment. Since it is necessary, it takes a lot of time, and there is a problem that the yield is greatly deteriorated if the mask alignment is defective. In the case of the thick film type, although the masking step is reduced, a masking step is still required for filling the insulating material, and thus has the same problem as the thin film type.

In addition, plating is exclusively applied to a method of forming a conductive pattern on a printed circuit board. Electroless plating applied to electrically connect the upper and lower surfaces is performed by plating an underlayer in advance and then plating a conductive material. It is usually troublesome to carry out the plating process twice, and there is a great deal of work in performing the plating process. Further, in the case of a ceramic wiring board, the hole provided in the ceramic substrate is electrically connected to the front and back with a conductive material usually called a via, but the via forming method is to fill the hole with an ink dispersed with a conductive material by printing, The formation of the conductive pattern on the front and back sides and the formation of the via portion are difficult to perform in the same process because of sintering to make it conductive. In addition, since printing is performed, a protruding portion is easily generated in a region other than the conductive pattern. was there.

Further, when an optical filter or an optical recording medium or the like is manufactured by combining materials having different optical characteristics and laminating opaque components in the form of granules or layers, the particle size of the opaque components or the thickness of the layers is not uniform. In addition, there is a problem that the surface precision of the dispersion or layer formation of the granular material is not uniform, and the optical characteristics as designed are often not obtained. In addition to the above problems, according to a conventional manufacturing method in which a plurality of types of alloys, for example, are formed by a so-called vapor deposition method such as evaporation or sputtering, each component is formed in an atomic state. In addition, the composition of a thin film after film formation is often different from that of a deposition source, and there is also a problem that it is difficult to control the composition of the thin film.

In recent years, various types of prototyping for producing various three-dimensional structure shapes based on design drawings or computer information have been attempted, and a method of exposing and laminating a photosensitive resin, a method of cutting and superposing thin plates with a laser, Alternatively, a method of irradiating a powder with a laser to solidify the powder has been proposed. However, the material applicable to the method of manufacturing the three-dimensional structure is limited to some resins, and it is difficult to obtain sufficient strength even when, for example, solidifying metal powder with a binder,
Further, for example, it is difficult to realize a structure in which the upper layer is larger than the lower layer.

Therefore, an object of the present invention is to provide a method of manufacturing a composite structure which has solved the above-mentioned problems. Also,
An object of the present invention is to provide a composite structure composed of a plurality of types of substances having different properties.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention provides a method for intermittently or continuously discharging and supplying at least one of a plurality of types of substances having at least one of electrical characteristics and optical characteristics different from each other. This is a manufacturing method including a forming step of forming a continuous structure or a first structure (hereinafter, referred to as a structure), and a supplying step of supplying another material different from the material of the structure. By controlling the supply time of the granular material in the forming step, it is possible to freely form a material from each independent granular material to a continuous structure to which the substance is continuously discharged and supplied.
In addition, by controlling the particle diameter or the continuous discharge amount of the granular material in the forming step, the particle width of the granular material to be formed or the formation width and / or thickness of the string-like continuous structure or the planar structure is controlled. Can be set freely. However, the string-like structure or the planar structure in the present invention includes not only a structure in which a substance is continuously discharged and supplied but also a state in which particulate matter is continuous, and the thickness, width, appearance, etc. of the structure. Which do not prescribe, as noted above, the delivery time of the substance and / or
Alternatively, it can be set freely by controlling the supply amount of the substance.

Further, when the forming step is two-dimensionally scanned, a two-dimensional granular material or a planar continuous structure can be formed.
When three-dimensionally scanned, three-dimensional particles or continuous structures can be formed. Therefore, by appropriately selecting the material to be applied to each of the forming step and the supplying step, for example, the optical recording material is dispersed in an optically transparent material or the optical recording material and the optically transparent material are laminated. A recording material, for example, an optical filter in which a light-shielding material is dispersed in an optically transparent material, for example, a composite material in which the dielectric properties can be controlled by the configuration of a conductive material dispersed in an electrically insulating material, for example, on a conductive material Alternatively, a two-dimensional or three-dimensional conductive anisotropic composite material in which an electrically insulating material is dispersed in a conductive material, for example, a two-dimensional or three-dimensional wiring board in which a conductive material is formed on or in an insulating material, for example, A composite structure having various functions can be manufactured, such as a heating device or the like in which a conductive material and a resistive material are formed on an electrically insulating material.

In the forming step of the present invention, since the powder is supplied in a granular form,
For example, unlike a film forming method in an atomic state such as a normal vapor deposition method such as a sputtering method or a vapor deposition method, the composition of a substance including a plurality of components such as an alloy can be uniformly supplied to the composite structure. The microscopic characteristics of any granular material, continuous structure or first structure can be uniformed. In the method of manufacturing a composite structure according to the present invention, if the accumulated thickness in the supply step is made substantially equal to the thickness formed in the forming step, substances having different functions accumulate except for the surface of the formed structure (hereinafter referred to as accumulated matter).
Therefore, for example, adjacent structures can be separated by substances having different functions, and the surface of the structures is exposed in the accumulation direction,
For example, a three-dimensional composite structure in which granules are stacked on the exposed portion of the structure, or a composite structure that can utilize the independent function of either the structure or the accumulation of the exposed portion can be easily manufactured. However, if the accumulation thickness of the accumulation is greater than the thickness of the structure, a composite structure having a structure wrapped with the accumulation can of course be formed. Note that if the substance applied to the supply step is liquid at least in the atmosphere of the supply step, the supply step can be performed by a simple method such as flowing the liquid substance, so that the step can be simplified.

In addition, by repeating the forming step and the supplying step a plurality of times, the accumulation and the structure can be laminated according to the number of times of repetition. For example, the upper structure is provided immediately above the lower structure. Any one of a configuration, a configuration including an upper-layer structure in a region other than the projection plane of the lower-layer structure, and a configuration including an upper-layer structure in a region partially overlapping the projection surface of the lower-layer structure. It can be freely selected as appropriate. The substance applied when the formation process is performed on the structure in a granular manner in at least one of the formation direction of the formation process and the accumulation direction of the supply process is performed in either the formation process or the supply process. Or another substance.

For example, if the same substance as in the forming step is grown in the direction of accumulation in the supply step, a structure having the same function having a three-dimensional spread can be formed. For example, a resistive material is continuously grown on a conductive material. When the conductive material is continuously grown after the heating, a heating element can be manufactured. Since a plurality of kinds of substances applicable to the present invention are different in at least one of an electric property and an optical property, a combination of a metal and a dielectric, an alloy and a dielectric, and the like are given. Other than these combinations, for example, a metal and a resistive substance, a plurality of kinds of metals having different color tones, or a plurality of kinds of dielectrics having different dielectric properties are often used. Among them, as one of the features of the present invention,
The method is characterized in that a metal or an alloy is applied, and in particular, there is a remarkable feature in a manufacturing method in which a metal or an alloy is applied to a substance used in a forming step of supplying particles. One of the plurality of types of substances is preferably a dielectric, and as the material of the dielectric, an inorganic material or an organic material can be applied,
In particular, the application of a so-called photo-curable resin that is three-dimensionally cured by irradiation of energy rays such as ultraviolet rays and X-rays,
It is preferable in terms of workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the concept of the basic structure of a composite structure manufactured by the manufacturing method of the present invention will be described with reference to the drawings, taking as an example a case where two kinds of substances having different properties are applied.
1 to 4 are conceptual process diagrams illustrating the manufacturing method, and FIG. 5 is a perspective partial sectional view showing a composite structure manufactured by the method. In the present invention, a first forming step is performed in which the substance once liquefied from the particulate matter generation means 10 is supplied to the support 30 as the granular material 20 and is fixed to the support 30 as a structure (21A to 21E). After the first forming step is completed, a substance 40 having a property different from that of the granular material 20 is supplied from a supply unit 50 to a region other than the region where the structures (21A to 21E) are attached, and the structure (21A) is formed. 21E), an accumulation 41 of the substance 40 is provided and a first supply step is performed. After the first supply step, the granular body 20 is supplied from the granularity generation means 10 onto the structures (21A to 21E) in the same manner as in the first formation step, and the second structure (22A to 22D) is stacked. Is formed, and after the second forming step, the structures (22A to 22D) are formed using the same method as in the first supplying step.
A second supply step of providing an accumulation 42 of the substance 40 around the substrate is performed, and the formation step and the supply step are repeated in this manner to produce a composite structure.

The material supplied from the particulate matter generating means 10 can be made into a liquid state by heating and melting the material, dissolving the material in a good solvent, or dispersing the material in a solvent. Above all, the method of heating and melting is preferable since it is only necessary to cool the granules after fixing the granules to the support 30 or the structure (21 or 22), and it is not necessary to remove the solvent. As a means for heating the substance, direct or indirect heating by a heater or the like, spark heating by electric discharge, and the like can be used. The state of liquefaction of the substance does not necessarily have to be completely liquefied.
It is sufficient that it can be supplied in the form of granules.
If the viscosity of the substance in the pores, the pressure, the diameter of the pores, etc. are kept constant,
The volume of the granular material 20 can be made constant. Granular material generating means 10
Examples of the pressure applying means include a so-called piezoelectric element that operates an electrostrictive element according to an electric signal, a fluid force of a base, gravity, and the like, and a combination thereof can be appropriately selected.

The appearance of the granular material 20 is determined by the granularity generating means 1.
By controlling the zero pore, pressure, viscosity of the substance, etc., it is possible to freely set from a spherical body to a shape having a tail. In particular, when the granular material 20 is generated by melting a substance, the surface state of the granular material 20 has an adhesive force enough to be fixed to at least the surface of the support 30 or a structure (21 or 22 or the like). In this case, the structure can be independently laminated, and the outer surface shape of the laminated structure can be controlled from the uneven shape to the planar shape by the temperature of the granular material 20 when the structure is fixed. In the case where the structures are independent as individual granules, the surface state of the granules 20 does not have to be particularly sticky.

FIG. 1 shows a state in which a first-layer structure 21 is formed. That is, this drawing shows a state in which the formation of the scanning line 21A of the fifth column is completed while the formation of the scanning line 21D of the fourth column is completed from the scanning line 21A of the first column. Therefore, the granularity generating means 10 sequentially moves in the direction perpendicular to the paper surface while supplying the granular material 20, and completes the first forming step. FIG. 2 shows that after the first forming step, a substance 40 having a property different from that of the granular material 20 is supplied from the supply means 50 to a region other than the region where the structures (21A to 21E) are applied, The accumulation 4 is formed around the structure 21 (21A to 21E).
1 shows a state surrounded by 1, and the accumulated matter 41 reaches a predetermined area.
Is supplied, and the first supply step is completed. FIG. 3 shows that, after the first supply step, the granularity generating means 1 is similar to the first forming means.
0 shows a step of supplying the granular material 20 from above, and stacking the structures 22 between the structures 21 of the first layer. FIG. This shows a state in which the formation of the fourth row of scanning lines 22D is completed, and the formation of the fourth row of scanning lines 22D is completed, thereby completing the second forming step. FIG. 4 shows that after completing the second formation step, the substance 40 is supplied from the supply means 50 to the structure (2) in the same manner as in the first supply step.
2A to 22D) are supplied to the area other than the area where the structure 22 is fixed, and the structure 22 (22A to 22D) is surrounded by the accumulation 42, and the accumulation 42 is supplied to a predetermined area. Finishes the supply process.

Thereafter, the forming step and the supplying step are sequentially repeated to complete the composite structure as shown in FIG. In the above description, the case where the forming step and the supplying step are alternately repeated in order has been described. However, for example, in the case of a continuous structure having no cavity therein as shown in FIG. When the substances accumulated around the same material are the same, it is not necessary to alternately repeat the forming process and the supplying process in order, and only the forming process is performed to produce a structure having a predetermined shape. It is also possible to do. When manufactured by such a method, there is a preferable point that there is no boundary between the accumulations accumulated by different supply steps, and the characteristics of the accumulations can be made more uniform. Further, in the above description, one grain generating means is provided. However, when a multi-type having a plurality of one-dimensional or two-dimensional grain generating means is used, the time of the forming process is reduced, and It goes without saying that the present invention can be applied to a case where an independent grain generating means is provided according to the hole diameter, the pressure, the heating temperature, the type of the substance, and the like. Further, in the above description, each accumulation is formed to have a thickness substantially equal to the thickness of the structure formed in one formation step. However, the accumulation may be thicker than the thickness of the structure formed in each formation step. In this method, only the structures formed in each forming step are separated from each other by the accumulation, and can be appropriately selected depending on the application. In the above description, one substance was used for each of the formation step and the supply step. However, a plurality of substances may be independently used for each step.

FIG. 6 is a sectional view showing the structure of a phase change type optical information recording medium according to an embodiment of the composite structure manufactured by using the manufacturing method of the present invention. One main surface of the polycarbonate substrate 601 is subjected to plasma treatment to form a hydroxyl group on the surface, the polycarbonate substrate 601 is immersed in a solution of tetrachlorosilane (SiCl ₄ ) dissolved in a non-aqueous solvent, washed with water, and subjected to plasma treatment.

A supply step of providing a body layer was performed.

Next, a forming process using the structure forming apparatus shown in FIG. 7 was performed. That is, the Ge / Sb / Te-based alloy is supplied from the material supply means 701 to the granular material generating means 702, and discharged by the discharge generating circuit 703 in the nozzle of the granular material generating means 702 to liquefy the alloy, and
04 is ejected by the pressure of a piezoelectric element (not shown),
Ge · Sb is deposited on the accumulation 602 provided on the substrate 601.
The Te-based alloy particles 603 were fixed. Thereafter, in the same manner as that of the accumulation material 602, the supply step of the accumulation material 604 was repeated until the granular material 603 was surrounded, thereby forming the first recording layer. Next, in the same manner as in the first recording layer, the granular material 60
3 and the accumulation 604 were formed to form the second recording layer. However, the difference from the first recording layer is that the second recording layer other than the projection surface of the granular material 603 in the first recording layer. That is, the granular material 603 is configured. The forming step and the supplying step are repeated a plurality of times until the thickness of the recording layer reaches a predetermined value. Finally, the reflective layer 605 is formed using an Al—Cr-based A continuous structure of an alloy was prepared to obtain a recording medium having a recording layer in which a Ge / Sb / Te phase change recording material was dispersed in a granular form. In the above description, the projection surfaces of the granular materials 603 of the adjacent recording layers do not overlap, but this is the case with the polycarbonate substrate 601.
Of course, it is only used to increase the absorption efficiency of laser light incident from the surface, and it is also possible to adopt a configuration in which the laser light is superimposed on the granular material 603. In addition, the Ge.
Since the Sb / Te-based alloy was formed as granules by discharging the granules by the granulation generating means, each composition of Ge / Sb / Te was uniform over all the granules.
