- the present invention relates to multilayer resin sheets. Furthermore, the present invention relates to a support-attached multilayer resin sheet, a printed wiring board, and a semiconductor device obtained by using the multilayer resin sheet. The present invention also relates to a method for producing a printed wiring board using the multilayer resin sheet.
- the insulating layer is generally formed by laminating a resin composition layer on a circuit board using a resin sheet or the like containing a resin composition layer and curing the resin composition layer.
- a resin composition layer is laminated on a circuit board using a resin sheet having a plurality of resin composition layers, and the resin composition layer is thermally cured to obtain a cured product, A technique for roughening the cured product to form a thin insulating layer having excellent mechanical strength is disclosed.
- the surface of the cured product formed by curing the resin composition layer corresponds to the surface undulations of the underlying circuit board (due to the surface unevenness associated with the presence or absence of circuit wiring, etc.). In some cases, undulations occurred, and the flatness of the surface was sometimes poor. If the surface flatness is poor, when forming a conductor layer (wiring layer) on the cured product, the adhesion between the pattern-formed dry film and the insulating layer tends to decrease, resulting in poor formation of fine wiring.
- the undulations on the surface of the cured product can be somewhat reduced by manipulating the lamination conditions of the resin composition layer. In some cases, the adhesiveness between the insulating layer and the conductive layer formed thereon is lowered.
- the present invention provides a novel resin sheet that provides a cured product with good surface flatness and good adhesion to a conductor layer even when laminated on a lamination target member having an uneven surface.

- D1 be the average particle size ( ⁇ m) of the inorganic filler in the first resin composition layer
- D2 be the average particle size ( ⁇ m) of the inorganic filler in the layers other than the first resin composition layer.
- T is the thickness ( ⁇ m) of the multilayer resin sheet and t is the thickness ( ⁇ m) of the first resin composition layer, t ⁇ (T ⁇ t) [1] to [ 3].
- a multilayer resin sheet according to any one of [1] to [6] is placed on an inner layer substrate, and the surface of the multilayer resin sheet opposite to the first resin composition layer is bonded to the inner layer substrate.
- a novel resin sheet that provides a cured product having good surface flatness and good adhesion to a conductor layer even when laminated on a member to be laminated having surface irregularities. can do.
- the multilayer resin sheet of the present invention it is also possible to produce a cured product exhibiting low surface roughness after roughening treatment.
- the multilayer resin sheet of the present invention comprises two or more resin composition layers, and when dynamic viscoelasticity measurement is performed at a frequency of 6.28 rad/sec, the first resin composition layer, which is one of the outermost layers, G'(A) is the elastic modulus (Pa) of the layer, and G'(B) is the elastic modulus (Pa) of the layer excluding the first resin composition layer. (B)))-(Log10(G'(A)) at 100°C) is -2 or more and less than 0.
- the multilayer resin sheet of the present invention has a structure in which two or more resin composition layers are laminated together.
- the first resin composition layer and the second resin composition layer Both are outermost layers.
- the outermost layers are the first resin composition layer and the Nth resin composition layer when numbered in ascending order from Nth.
- the multilayer resin sheet of the present invention is used by being laminated on a member to be laminated (for example, an inner layer substrate to be described later). At this time, the surface ( The other outermost layer; in a multilayer resin sheet consisting of two resin composition layers, the second resin composition layer, and in a multilayer resin sheet consisting of N resin composition layers, the Nth resin composition layer. applicable) is laminated and used so as to be joined to the member to be laminated. Therefore, when laminated on a member to be laminated, the first resin composition layer is on the outside (external environment side), so the first resin composition layer may be simply referred to as the "outer layer" below.
- the layers other than the first resin composition layer are laminated with the first resin composition layer after being laminated on the member to be laminated. Since it is located between the target member, the layers other than the first resin composition layer may be simply referred to as "inner layer” below.
- the number of resin composition layers may be two or more, and may be three or more.
- the multilayer resin sheet of the present invention may be formed by making a difference in the content of each component in the resin sheet substantially in one resin sheet. In this case, the portion where the content of each component is different can be interpreted as the layer interface.
- the elastic modulus (Pa) of the first resin composition layer which is one of the outermost layers, was G'( A) and the elastic modulus (Pa) of the layer excluding the first resin composition layer is G'(B), (Log10(G'(B)) at 100°C) - (at 100°C Log10(G'(A))) is -2 or more and less than 0.
- the multilayer resin sheet of the present invention is laminated on a member to be laminated having an uneven surface, the surface flatness is good, and the adhesiveness (adhesive strength) to a conductor layer such as a plated conductor layer is improved. can also provide good cured products. Moreover, according to the multilayer resin sheet of the present invention, it is possible to provide a cured product with a low surface roughness after the roughening treatment.
- the dynamic viscoelasticity measurement can be performed according to the method described in the section [Dynamic viscoelasticity measurement] below, using a Rheometer device ("AR-2000" manufactured by TA Instruments) at a frequency of 6 .28 rad/sec, 60° C. starting temperature, 5° C./min heating rate, and 0.75% strain.
- AR-2000 manufactured by TA Instruments
- the reason why the elastic modulus G′ at 100° C. is used is that the lamination processing temperature generally used when processing a resin sheet that does not contain a fiber base material such as glass cloth is taken into consideration.
- the above dynamic viscoelasticity measurement is performed at a frequency of 6.28 rad/sec to simulate and reproduce the molding speed during lamination processing.

Abstract
La présente invention concerne une nouvelle feuille de résine qui présente une bonne planéité de surface même si elle est superposée sur un élément d'objet d'empilement qui présente une surface irrégulière, tout en permettant l'obtention d'un produit durci qui présente une bonne adhérence à une couche conductrice. Cette feuille de résine est une feuille de résine multicouche qui est pourvue de deux couches de composition de résine ou plus, tout en étant caractérisée en ce que si G'(A) est le module d'élasticité (Pa) d'une première couche de composition de résine qui sert de couche la plus à l'extérieur, et G'(B) est le module d'élasticité (Pa) de couches autres que la première couche de composition de résine, lors de la réalisation d'une mesure de viscoélasticité dynamique de la feuille de résine multicouche à une fréquence de 6,28 rad/sec, ((Log10(G'(B)) à 100°C) – (Log10(G'(A)) à 100°C)) est supérieur ou égal à -2 mais inférieur à 0.
