relates to a conductive sheet suitable for various substrates or parts used in electrical products, electronic products, semiconductor products, automobiles, and the like. [Prior art] Conventionally, conductive sheets used in electrical products, electronic products, semiconductor products, etc. are used to make rolled or electrolytic foils of various metals centered on copper as conductive layers, which are bonded to each other through an adhesive. It is used on an insulating film. In addition, the surface of the aforementioned foil is subjected to roughening treatment or a black treatment by a metal such as Ni, Ti, Cr, etc. without passing through the adhesive, and then on these conductive layers, It can be used by directly applying insulating resin or heat-fusion. On the other hand, it is also known that as a conductive layer, a metal such as copper is laminated on an insulating film using a vacuum technique such as sputtering or vapor deposition, or after the conductive layer is laminated, The electroplating method adds a conductive sheet having a thickness. However, in any of the conductive sheets, the adhesive force between the conductive layer and the insulating film is weak, and the adhesive strength (peel strength) cannot be satisfied. In addition, in order to improve the adhesion, it is attempted to roughen the surface of the insulating film instead of the conductive layer, or to insert Cr, Ni between the conductive layer and the insulating film by using it. And Ti metal layers to prevent oxidation of copper and other metals constituting the conductive layer in order to improve its adhesion, but by these methods -4- (2) 1240932 achieves a certain degree of adhesion improvement, No matter what kind of attempt is being made, the so-called cause of difficulty or other problems will also arise in forming a miniaturized circuit pattern. In addition, it is also proposed to improve the cohesion by combining the two technologies mentioned above. That is, in Japanese Unexamined Patent Publication No. 2001-277424, it is proposed that the surface of the polyimide film be roughened, and an intermediate layer composed of molybdenum or silicon be formed on the roughened surface. On it, a metal layer is formed. However, even in this attempt, the surface of the polyimide film used as the insulating film was roughened so that it was difficult to form a fine circuit pattern due to the unevenness of the surface. In addition, the thickness of the aforementioned intermediate layer is determined in conjunction with the surface roughness Ra of the roughened surface. Therefore, it is also assumed that the thickness of the intermediate layer becomes too thin to exert its effect as an intermediate layer. On the other hand, Japanese Patent Application Laid-Open No. 2002-192646 describes a gas barrier film having an oxide film on a substrate. However, it does not show improvement in adhesion of the conductive layer, nor does it show improvement in miniaturization. Formation of circuit patterns. In addition, in Japanese Patent Laid-Open No. 10-192773, Japanese Patent Laid-Open No. 11-29645, Japanese Patent Laid-Open No. η-4055, Japanese Patent Laid-Open No. 5-88851, Japanese Patent Laid-Open No. 2002-317046, and Japanese Patent No. Publication No. 2002-2 73 830 describes substrate sheets such as polyimide films. However, even in these publications, the adhesion strength of the conductive layer is not shown, and the fineness is not shown. Formation of a transformed circuit pattern. -5- 1240932 (3) [Summary of the invention] Φ The invention is constructed in view of the foregoing situation; its purpose is to provide a circuit pattern that can be miniaturized and improve the adhesion between the body sheet and the conductive layer that becomes an insulating film. Furthermore, it is a conductive sheet that improves the moisture absorption of the base sheet and ensures a high degree of dimensional stability while also having good high-frequency characteristics. In order to solve the aforementioned problems, the present inventors made an intensive and repetitive investigation to obtain the idea of improving the adhesion with the conductive layer when reducing the water content of the base sheet, and also obtained that if a certain layer is used, On the other hand, if the substrate sheet is coated, it is possible to prevent the moisture absorption over time, and when the research is repeated based on these opinions, the present invention has finally been completed. That is, the conductive sheet of the present invention is characterized in that it has a surface that is not subjected to surface roughening treatment, and an insulating film that has a content of volatile components containing moisture to 1% by mass or less, and is a base sheet. A silicon-containing layer is formed on the surface of at least one side of the front and back of the base sheet, and a conductive layer is formed on the silicon-containing layer. By adopting such a structure, the adhesion between the base sheet and the conductive layer can be improved, and the surface of the insulating film is not roughened. Therefore, it is possible to form a finer pattern without causing difficulties. As described above, it is considered that the high adhesion force between the base sheet and the conductive layer is caused by the following reasons. That is, it is thought that the decrease in the adhesion force in the conventional conductive sheet is mainly due to the influence of volatile components such as moisture contained in the base sheet, and it is considered that 'the presence of volatile components such as moisture in this way- 6-(4) 1240932 minutes, which promotes the oxidation of the metal constituting the conductive layer and significantly reduces the adhesion force to the base sheet is the reason. On the other hand, the aforementioned structure of the present invention emphasizes these factors more. By selecting an insulating film having a volatile component content of 1% by mass or less to form a base sheet, the base sheet is laminated on the base sheet. Contains a silicon layer to prevent the substrate sheet from absorbing moisture over time. In addition, the conductive sheet of the present invention is characterized in that it has a surface that is not subjected to surface roughening treatment, and an insulating film that has a content of volatile components containing moisture to be 1% by mass or less, and becomes a base sheet. A silicon-containing layer is formed on the surface of the substrate sheet on the front and back sides, and a conductive layer is formed on the silicon-containing layer on one side. With such a structure, it is possible to further prevent moisture absorption of the base sheet, and at the same time, it is possible to form the entire conductive sheet to ensure high dimensional stability and improve high-frequency characteristics. In addition, in the present invention, the conductive layer may have a laminated structure in which a second conductive layer is formed on the first conductive layer, and an intermediate metal layer may be formed between the silicon-containing layer and the conductive layer. In addition, the conductive sheet of the present invention may be processed with one or more holes, such as holes, through holes, or alignment holes. In addition, in the present invention, the content rate of volatile components such as moisture is 1% by mass or less is based on the state before and after heating and drying the base sheet or the conductive sheet for 30 minutes at 105 ° C. Quality change. (5) 1240932 [Embodiment] < Conductive sheet > As described above, the conductive sheet of the present invention has a film as a base sheet, and a plurality of layers are laminated on the base sheet. The following description is made of each structure. < Substrate sheet > The substrate sheet of the present invention is formed by having a rough surface without making the water content ratio 1% by mass or less. Since the surface roughening treatment is not performed, a circuit pattern can be formed, and the density between the insulating film and the conductive layer can be highly improved by making the volatile content rate containing water less than or equal to 1% by mass, regardless of whether or not the surface is roughened. Heli. The so-called volatile components mentioned here are mainly moisture, but other components include residues present in the insulating film. Examples of such insulating film systems include synthetic tree thermoplastic elastomer films and rubber films. Examples of the synthetic resin include films made of a combination of PET, PEN, acrylic, nylon, polyethylene, vinyl chloride, polyimide, liquid crystal polymer, and epoxy. Examples of the thermoplastic elastomer film system include films made of a thermoplastic elastomer such as ethylene-based, vinyl chloride-based, olefin-based, urethane-based, or amine-based. Examples of the film system include natural rubber, butadiene rubber, chloroprene rubber, styrene-butadiene rubber, and an insulating structure. The marginal film of chemical treatment forms chemical treatment of fine components, and it is also used as a monomer. Lipid film, film system, polypropylene resin, such as phenyl ester system, rubber is thin, isoprene nitrile rubber, -8-1240932 (6) butyl rubber, ethylene-propylene rubber, acrylic rubber, amine-based Film made of synthetic rubber such as ethyl formate rubber, fluorine rubber, and silicone. The types of synthetic resins, thermoplastic elastomers, or rubbers listed here are examples and are not limited thereto. In the present invention, the types of the aforementioned synthetic resin, thermoplastic elastomer, or rubber can be selected according to the application. For example, in applications where heat resistance is required, polyimide or liquid crystal polymer is the best choice for synthetic resin systems. In a state where heat resistance is not required, P ET and the like are suitable in consideration of cost, etc., and in applications where elasticity is required. Suitable for choosing thermoplastic elastomer or rubber. In addition, the purpose is to increase the strength of the insulating film and provide a flame retardant effect. For example, various fillers such as glass fiber can be added. On the other hand, such an insulating film is suitable for a thickness of 4 to 200 // m, preferably 10 to 100 // m. In a state where the thickness is less than 4 // m, it is not easy to fully function as a base system for supporting a conductive layer described later. On the other hand, in a state exceeding 200 μm, it becomes economically expensive. It is disadvantageous, or lacks flexibility, and is not easy to be processed into a roll-like shape. In addition, the shape of the insulating film is not limited in any way, and examples thereof include a continuous one (roller-shaped) or a sheet-shaped user (thin-shaped). The surface roughness of the insulating film is preferably 0.1 to 5 // m, preferably 11 to 2 // m. When considering the correspondence to the miniaturization of circuit patterns, it is indeed ideal if Ra 値 becomes smaller. However, there are also cases where the manufacturing cost of the insulating film itself becomes high. Therefore, Ra must be selected in consideration of this aspect value. On the other hand, when Ra 値 becomes large, it is not easy to miniaturize the circuit pattern due to the relationship between the surface irregularities. Therefore, it is preferable that R a 値 below is 2 v m or less. However, it can be said that a wide range of Ra series can be used, which is due to the aspect of ensuring the dimensional stability based on the reduction in the structure of the present invention. In addition, such an insulating thin film is as described above. The content of the volatile component of the water content is 1 mass, preferably 0.5 mass% or less, and more preferably 0.1 mass. The insulating thin film used in the present invention is the most Fortunately, before each layer, a drying process is performed. Such a dry place is, for example, a method of heating to 40 to 200 ° C, preferably 60-vacuum state (1 X 1 0 · 3 to 1 · 5 X 1 0 · 1 P a). < Silicon-containing layer > The silicon-containing layer of the present invention is laminated and formed on at least one of the aforementioned surfaces or both surfaces. Such a sheet-containing sheet has the effect of effectively preventing the base sheet from absorbing moisture and imparting high-frequency characteristics. In addition, when the conductive layer described by the silicon-containing layer is etched by acid or alkali, it will not be removed due to such etching, and it remains here. It is best that the aforementioned action system is not reduced by uranium etching. It is formed on the front and back surfaces of the base sheet. The conductive layer and the like described above do not necessarily have to be formed in such a manner that 5 β m ′ is suitable. In any case, the hygroscopic property achieved by one feature of the invention must be less than or equal to the package%, and the optimum amount or less. Therefore, the method described below can be used to coat the substrate on the front and back silicon layers of the substrate sheet under vacuum heating and drying at a temperature of -180 ° C. At the same time, it can also be used to form circuit pattern substrate sheets on the back. Because less. In this state, such a silicon-containing layer may be formed on the silicon-containing layer on one of the sides -10- (8) 1240932. Such a silicon-containing layer is formed by one of an amorphous si, a crystalline S: sand (SiO) or a sand dioxide (si02). As the formation method, it is preferable that the amorphous Si is suitable for the state of -20 ° C ~ 180 ° C under the condition of sputtering. Above the temperature, on the one hand, the thickness of the silicon-containing layer is suitable to be 80A to 3 # m 5 00A to 5,000 A. In the state where the thickness is less than 80A, the substrate is removed by the aforementioned etching process or the substrate is not fully wet. The effect is prevented, and cracks are generated in the state where the conductive thin sheet is bent more than 3 μ, so they are all similar. < Conductive layer > The conductive layer of the present invention is laminated and formed on the aforementioned silicon-containing layer, and is mainly composed of a conductive metal such as copper, and has a function of imparting a conductive sheet. In the present invention, it may be a conductive layer. However, as described below, it is preferable to have a laminated structure in which a second conductive layer is formed on the conductive layer. < First conductive layer > The first conductive layer of the present invention is formed by forming a metal on the surface in a state where the intermediate metal layer described in the aforementioned silicon-containing layer is formed. The first conductive layer is formed of two or more kinds of oxides having the same conductive characteristics as i, and is formed at a temperature of. In addition, it is best to ignore the sheet due to the suction of the sheet. Usually, a single layer of pre-conductivity is -11-1240932 (9) when the first layer is laminated on the first surface or back. (9) It is an adhesive auxiliary layer that strongly holds the second conductive layer described later on the substrate sheet. effect. A method for forming such a first conductive layer is preferably a sputtering method or a vapor deposition method. Next, as the conditions for the sputtering, a vacuum degree of 1x10 4 to 1.5xl0 "Pa, preferably ΙχΙΟ-4 to 1 χ l (T2Pa, current 0.000 1 to 15A / cm2, and preferably 0.01 to 0.5A) is suitable. / cm, Ar gas 50 ~ 400cc / minute, preferably 180 ~ 250cc / minute. In addition, the vacuum conditions are suitable for the vacuum! X 10 · 5 ~ 1.5xl (T2Pa, preferably 1 χ10.4 · l ~ lxl (T3Pa, current 0 · 0001 ~ 15A / cm2, preferably 0.001 ~ 10A / cm2. Conditions for the first metal system constituting the first conductive layer include copper, Nickel, zinc, gold, silver, tin, aluminum, titanium, cobalt, chromium, and alloys containing at least one of these metals. Next, copper (Cu) is particularly preferred. In addition, the thickness of the first conductive layer is based on It is suitable for 500 A to 2 / im, and preferably 1000 to 3 000 A. Since the effect as the aforementioned adhesion auxiliary layer is not sufficiently displayed in a state of less than 500 A, on the other hand, even if it exceeds 2 // m, also in the aforementioned effect, does not produce a large difference, on the contrary, it becomes economically disadvantageous. In addition, it will be described later 2 Before the formation of the conductive layer, it is preferable to perform the method on the first conductive layer by using sulfuric acid at a concentration of 0.5 to 50%, preferably 1 to 10%, for 0.1 to 3 minutes, preferably 0.5 to 1.5 minutes of acid activation treatment to facilitate activation. This acid activation treatment can be performed even when the first metal constituting the first conductive layer is oxidized (that is, Even when the first metal becomes Cu in the state where it is oxidized to become copper oxide), it is effectively reduced or dissolved to remove -12-1240932 do) This makes the second metal form a highly adhesive < Second conductive layer > The second conductive layer of the present invention is formed on the first conductive layer by the second metal. The first conductive layer mainly functions as a first adhesion auxiliary layer, and relatively, the second conductive layer functions to impart conductivity. Therefore, in order to ensure the conductivity, the second conductive layer must be formed thicker than the first. In other words, this second conductive layer is suitable for a thickness of 0.5 to preferably 1 to 35 // m. form. In the state where the thickness is less than 0, it does not show sufficient conductivity. On the other hand, even if it is over 50 M m, there is no large difference in conductivity. On the contrary, it becomes unfavorable. The second conductive layer is suitable for formation. As such a plating method, electroless plating or electric plating can be used; any method can be selected as the purpose. Here, examples of such a second conductive metal system include copper, silver, gold, nickel, chromium, zinc, iron, and alloys including one or more of these metals. This is followed by copper (Cu). In addition to showing extremely good conductivity, the first conductive layer is formed by copper (Cu), and a strong adhesion is obtained between the first conductive layer and this, so that the electric layer is formed on the first conductive layer. In the state formed by plating using such copper (Cu), the electroplating bath system is not particularly limited to the one conductive layer formed on the second conductive layer layer, which is mainly a conductive layer from a viewpoint. 50 // m, the most .5 // m is the formation of super, economically by electroplating, but also the thickness of the second layer, palladium, tin or, especially for the sake of the electric layer, In this state '. Electricity is performed in the second lead, but it is particularly preferable to use a copper sulfate plating bath. Due to the stress of being able. < Intermediate metal layer > The intermediate metal layer of the present invention is shaped as required. Such an intermediate metal layer has the function of forming an electrode of the former type. In particular, the aforementioned conductive layer is composed, and it is useful to form the intermediate metal layer only by a plating method. The first conductive layer or the second conductive layer is oxidized. In other words, the aforementioned silicon-containing layer mainly functions to absorb moisture. On the other hand, the intermediate metal layer is responsible for the moisture absorption and oxidation of the conductive layer or the second conductive layer, and the diffusion from the insulating film to the conductive layer is included. The squares are effectively captured or hidden. Having such an inter-oxygen metal layer is particularly effective in a state where the conductive layer is made of easily oxidized copper (CU), and in this state, there is no need to form it at all. As described above, this intermediate metal layer has a thickness between 20 to 50 to 100 A between the surface and the (first) conductive layer, and is made of nickel (Ni), cobalt (Co, titanium (Ti), chromium (Cr)). The oxides of these metals are formed by a group consisting of alloys of at least one of these metals. It is easy to adjust the electric ore film to the conductive layer of the aforementioned silicon-containing layer by one of the sputtering method and the evaporation method. 1 The second conductive layer is in a single state. In addition, the oxidation-preventive insulating film that is higher than the oxidation-preventive layer above the layer can prevent the aforementioned first function. This can neutralize the oxidation prevention effect of moisture and the like. Iron (Fe) or other metals are formed on the silicon-containing layer in the table 1 0 0 0 A, preferably), zinc (Zn), nitride, and a selected one to form a layer or 2 -14- (12) 1240932 and above. In the state where the thickness is less than 20 A, the front cannot be displayed. In addition, in the state where the thickness exceeds 1 000 A, it becomes difficult to make the circuit pattern small. In addition, the constituent components are limited to those in which the aforementioned metals are excellent in electrical conductivity or oxidation prevention effect, and are suitable for formation by a sputtering method or a vapor deposition method. For example, it is suitable to use a vacuum degree of 1 X 1 0 · 4 ~ 1. 5 X 1 (Γ 1 is preferably 1 × 10 · 4 to 1.5 × 1 (T2Pa) as a condition for forming the intermediate metal layer by a sputtering method. The current is 0.0001 to 15 A / c, preferably 0.01 to 0.5 A / cm2, and the Ar gas 100 to 400 cc / minute is 100 to 25 Occ / minute. In addition, the conditions are suitable in the state formed by evaporation. The vacuum conditions are 1x10 lCT2Pa, preferably lxl (T4 ~ lxlCT3Pa, current 0.0001 ~ cm2, preferably 0.001 ~ 10A / cm2. In addition, before forming the aforementioned (first) on the intermediate metal layer, It is preferable to perform acid activation treatment on the intermediate metal layer for 0.1 to 3 minutes and 0.5 to 1.5 minutes by using sulfuric acid with a concentration of 0.5, preferably 1 to 10%. Activation. This type of acid activation treatment can be performed to effectively reduce or dissolve and remove (1) the conductive layer into the intermediate gold with high adhesion even in the state where the intermediate metal layer is subjected to, for example, oxidation. < Hole processing > The conductive sheet system of the present invention can be made into holes, through holes, or the above-mentioned thinning effect. In the state, P a, the most m2, the most, and the best method are shaped. 5 ~ 1 X Μ 5 A / conducting layer ~ 50% It is best to process this with a metal, one or more of the aligning holes -15-1240932 (13) on the metal layer. These hole processing can be performed by punching, perforating, C02 laser, yttrium aluminum garnet (YAG) laser, excimer laser, and the like. Generally, the hole system can have a diameter of 10 to 3 0 β m, preferably 20 to 1 50 " m. It is not easy to form voids less than 10 // m, and when it exceeds 300 // m, it is not easy to apply buried holes. In addition, the through-hole system may be 1 0 0 // m to 3 m m, preferably 20 to 800 / im. It is because the voids are fully acted below 100 / im, and when it exceeds 3 mm, the proportion of the entire conductive sheet becomes too large. In addition, as the alignment hole system, the diameter can be 50 # m to 3 mm, preferably 200 // m to 1 mm. It is difficult to detect the alignment hole when it is less than 50 // m, and when it exceeds 3 mm, the accuracy of the alignment hole is deteriorated.
