Definitions
- the present disclosure relates to a multilayer wiring board and a semiconductor device.
- circuit materials such as circuit boards, particularly multilayer wiring boards suitable for high-frequency circuits, have become highly multilayered.
- a thermoplastic resin having a low dielectric constant and a low dielectric loss tangent excellent in high-frequency characteristics has been used as an adhesive layer for multilayering.
- a copper clad laminate including a copper foil bonded to a fluororesin insulating substrate As a multilayered fluororesin substrate, a copper clad laminate including a copper foil bonded to a fluororesin insulating substrate is known.
- the feature of this copper-clad laminate is that a copper foil having smooth surfaces that are not roughened or blackened is bonded to an insulating substrate through a composite film of LCP and PFA. Yes (Patent Document 1).
- a multilayer printed circuit board formed of a plurality of laminated fluororesin-based base layers and having at least one conductor layer therein has also been reported (Patent Document 2).
- the feature of this circuit board is that the base material layer provided with the internal conductor layer and the base material layer adjacent thereto are bonded to each other through an adhesive layer made of a liquid crystal polymer.
- liquid crystal polymer (LCP) having a high melting point is used for both the copper-clad laminate and the multilayer printed circuit board. Therefore, the phenomenon of misalignment between layers deteriorates. As a result, multilayering becomes more difficult.
- the inventors of the present invention have conducted intensive research and can suppress the positional shift between the layers and use an adhesive layer having excellent peel strength to reduce transmission loss of electric signals when using a fluororesin substrate.
- a multilayer wiring board capable of being suppressed was obtained.
- the present disclosure provides a multilayer wiring that can suppress a positional loss between layers and can suppress an electric signal transmission loss when a fluororesin substrate is used by using an adhesive layer having excellent peel strength. It is an object to provide a substrate and a semiconductor device using the same.
- the present disclosure relates to a multilayer wiring board and a semiconductor device that can solve the above problems by having the following configuration.
- a fluororesin substrate having a conductor pattern formed on at least one surface thereof, and an adhesive layer for adhering the fluororesin substrate, wherein the adhesive layer contains a cured product of a thermosetting resin.
- a multilayer wiring board having a breaking elongation of 20% to 300%.
- the adhesive layer includes a filler having a dielectric loss tangent of 0.002 or less.
- a multilayer wiring board that can be provided can be provided.
- the multilayer wiring board of the present disclosure includes a fluororesin substrate having a conductor pattern formed on at least one surface thereof, and an adhesive layer for bonding the fluororesin substrate, and the adhesive layer is a thermosetting resin. And has a breaking elongation of 20% or more and 300% or less.
- FIG. 1 is a schematic diagram showing an example of a cross section of a multilayer wiring board.
- FIG. 1 is an example of a cross section of a two-layer wiring board.
- a multilayer wiring board 1 shown in FIG. 1 includes a fluororesin substrate 30 having a conductor pattern 20 formed on at least one surface thereof, and an adhesive layer 10 for bonding the fluororesin substrate 30.
- the adhesive layer 10 contains a cured product of a thermosetting resin. Furthermore, the elongation at break of the adhesive layer 10 is 20% or more and 300% or less.
- via holes (through holes) 40 can be formed in the multilayer wiring board 1 as necessary.
- fluororesin substrate for example, a fluororesin substrate described in JP-A-07-323501 or JP-A-2005-268365 can be used.
- PTFE polytetrafluoroethylene
- fluororesin used for fluororesin substrates examples include polytetrafluoroethylene (PTFE), tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer (PFA), tetrafluoroethylene / hexafluoropropylene / perfluoroalkyl vinyl ether copolymer (FEPPFA), FEP, polychlorotrifluoroethylene (PCTFE), vinylidene fluoride resin (PVDF), vinyl fluoride resin (PVF), ethylene-tetrafluoroethylene copolymer (ETFE), and ethylene-chlorotrifluoro An ethylene copolymer (ECTFE) is mentioned.
- PTFE polytetrafluoroethylene
- PFA perfluoroalkyl vinyl ether copolymer
- FEPPFA tetrafluoroethylene / hexafluoropropylene / perfluoroalkyl vinyl ether copolymer
- FEP
- PTFE is preferable from the viewpoints of low dielectric constant, low dielectric loss tangent, heat resistance, chemical resistance, and the like.
- the melting point of PFA or the like is preferably 280 ° C. or higher.
- An example of the molding temperature of the fluororesin is 320 to 400 ° C.
- the fluororesin may be used alone or in combination of two or more.
- heat resistant insulating fibers examples include inorganic fibers such as glass fibers, silica fibers, alumina fibers, and aluminum silicate fibers, polyparaphenylene benzobisoxazole fibers (PBO fibers), aromatic polyester fibers, polyphenylene sulfide fibers, and Organic fibers such as wholly aromatic polyamide fibers can be mentioned.
- Glass fiber is preferable from the viewpoints of heat resistance, high strength, high elastic modulus, and low cost.
- the heat resistant insulating fibers may be used alone or in combination of two or more.
- Examples of the conductor pattern include copper wiring formed by etching copper foil.
- the adhesive layer contains a cured product of a thermosetting resin, and the elongation at break of the adhesive layer is 20% or more and 300% or less.
- the thermosetting resin imparts adhesion and heat resistance (melting resistance during heating) to the adhesive layer.
- the thermosetting resin is not particularly limited as long as it gives the adhesive layer a breaking elongation of 20% or more and 300% or less after the thermosetting.
- examples include modified polyphenylene ether, bisphenol A type epoxy resin, biphenyl type epoxy resin, naphthalene type epoxy resin, bismaleimide, special acrylate, and modified polyimide.
- a resin containing modified polyphenylene ether or modified polyimide is preferable from the viewpoint of the elongation at break and dielectric constant of the adhesive layer.
- a modified polyphenylene ether having an ethylenically unsaturated group (particularly, a styrene group) at the terminal is high in both low-polarity fluororesins because of its small polarity. Since it has adhesiveness, it is more preferable.
- an epoxy resin alone is not preferable because it has a low elongation at break and a high dielectric constant.
- the thermosetting resins may be used alone or in combination of two or more.
- An epoxy resin as a thermosetting resin may require a curing agent.
- the curing agent is not particularly limited. Examples include imidazole, amine, acid anhydride, and phenolic curing agents. From the viewpoint of reaction temperature and reaction time, an imidazole-based curing agent is preferable. 1-benzyl-2-phenylimidazole and 2-phenyl-4,5-dihydroxymethylimidazole are more preferred.
- Other resin can be contained in the adhesive layer.
- the other resin is added to improve the elongation when the thermosetting resin alone cannot give a breaking elongation of 20% or more to the adhesive layer after thermosetting.
- examples of other resins include polyolefin-based elastomers, especially styrene-based thermoplastic elastomers, polystyrene-poly (ethylene / butylene) block copolymers, polystyrene-poly (ethylene-ethylene / propylene) block copolymers. Etc. are mentioned. These hydrogenated elastomers are preferred because of their low dielectric constant and dielectric loss tangent.
- Other resins may be used alone or in combination of two or more.
- the elongation at break of the adhesive layer is preferably 20% or more and 300% or less from the viewpoint of peel strength with the copper foil.
- the elongation at break is less than 20%, the adhesive layer becomes hard and brittle. Therefore, the peel strength with the copper foil is weakened. If the elongation at break exceeds 300%, misalignment tends to occur during lamination.
- the elongation at break of the adhesive layer can be measured by an autograph.
- the adhesive layer preferably contains a filler having a dielectric loss tangent of 0.002 or less from the viewpoint of further reducing transmission loss of the multilayer wiring board.
- fillers having a dielectric loss tangent of 0.002 or less include fluororesin fillers and silica fillers (including hollow silica particles).
- the average particle size of the filler having a dielectric loss tangent of 0.002 or less is preferably 0.01 to 10 ⁇ m, more preferably 0.01 to 1 ⁇ m.
- the average particle diameter can be measured with a laser diffraction particle size distribution measuring apparatus (model number: LS13320) manufactured by BECKMAN COULTER.
- the filler having a dielectric loss tangent of 0.002 or less may be used alone or in combination of two or more.
- an additive can be further blended as necessary within a range that does not impair the purpose of the present embodiment.
- additives include leveling agents, antifoaming agents, thixotropic agents, antioxidants, pigments, or dyes.
- the tensile elastic modulus of the adhesive layer is preferably 1 GPa or less from the viewpoint of relaxation of internal stress of the multilayer wiring board as a laminate and peel strength between the fluororesin and the adhesive layer.
- the tensile elastic modulus of the adhesive layer is preferably 0.1 GPa or more from the viewpoint of pressure resistance during pressing. When the elastic modulus is less than 0.1 GPa, the heat resistance of the adhesive layer (such as during hot pressing) is inferior, and misalignment tends to occur.

Description
〔1〕少なくともその一面に形成されている導体パターンを有するフッ素樹脂基板と、前記フッ素樹脂基板を接着するための接着層と、を含み、前記接着層が熱硬化性樹脂の硬化物を含有し、かつ、20%以上300%以下の破断伸び率を有する、多層配線基板。
〔2〕前記接着層の引張り弾性率が、1GPa以下である、上記〔1〕の多層配線基板。
〔3〕前記接着層が、0.002以下の誘電正接を有するフィラーを含む、上記〔1〕または〔2〕の多層配線基板。
〔4〕前記フッ素樹脂基板の誘電率が100%であるときの、前記接着層の誘電率が、70~130%である、上記〔1〕~〔3〕のいずれかの多層配線基板。
〔5〕前記接着層上の伝送損失が、20GHzにおいて、0~-3dB/70mmである、上記〔1〕~〔4〕のいずれかの多層配線基板。
〔6〕上記〔1〕~〔5〕のいずれかの多層配線基板を含む、半導体装置。
なお、図1に示すように、多層配線基板1には、必要に応じ、ヴィアホール(スルーホール)40を形成することができる。
フッ素樹脂基板としては、例えば、特開平07-323501号公報あるいは特開2005-268365号公報に記載のフッ素樹脂基板を使用できる。具体的な例として、ガラスクロスに、ポリテトラフルオロエチレン(PTFE)を含浸保持させて得られる、プリプレグから構成したリジッド基板、および、フッ素樹脂繊維と、ガラス繊維などの耐熱性絶縁繊維と、を用いて、湿式抄紙法にて形成することにより得られる、いわゆる抄紙シートが、挙げられる。
接着層は、熱硬化性樹脂の硬化物を含有し、かつ、この接着層の破断伸び率は、20%以上300%以下である。
上述のとおり、本開示の多層配線基板は、少なくともその一面に形成されている導体パターンを有するフッ素樹脂基板と、そのフッ素樹脂基板を接着するための接着層と、を含む。その接着層は、熱硬化性樹脂の硬化物を含有し、かつ、20%以上300%以下の破断伸び率を有する。この多層配線基板は、フッ素樹脂基板と接着層との間のピール強度、および導体パターンと接着層との間のピ-ル強度に優れる。この優れたピ-ル強度の原因は、投錨効果(アンカー効果)による、と考えられる。接着層の破断伸び率が、導体(銅箔)とのピール強度に寄与することが考えられる。破断伸び率が20%未満または300%を超えると、銅箔ピール強度は弱くなる。なお、フッ素樹脂基板と接着層と間のピール強度が高いため、ピール試験では、フッ素樹脂基板と銅箔との間で剥離が生じたり、フッ素樹脂基板自体が破壊される場合がある。
