    • Disclosed are a multi-layer substrate and a manufacturing method of the multi-layer substrate. By employing a carrier to alternately form dielectric layers and metal structure layers thereon. Each dielectric layer adheres with the adjacent dielectric layer to embed the metal structure layers in the dielectric layers corresponding thereto. Comparing with prior arts, which have to use prepregs when hot pressing and adhering different layers of different materials, the present invention takes fewer processes, thus, fewer kinds of materials without using prepregs. Therefore, the present invention can promote the entire quality and yield of manufacturing the multi-layer substrate to satisfy mechanical characteristic matching of the multi-layer substrate and to reduce cost of the whole manufacturing process. Significantly, the multi-layer substrate having thin dielectric layers according to the present invention can satisfy the concern of impedance matching therefore, and can reduce crosstalk influence to keep good signal integrity therein.
    • 公开了多层基板的多层基板和多层基板的制造方法。 通过使用载体交替地在其上形成介电层和金属结构层。 每个电介质层与相邻的电介质层粘合以将金属结构层嵌入与其对应的电介质层中。 与现有技术相比,当热压和粘附不同材料的不同层时,必须使用预浸料,本发明采用较少的工艺,因此在不使用预浸料的情况下,材料种类较少。 因此,本发明可以提高制造多层基板的整体质量和产率,以满足多层基板的机械特性匹配并降低整个制造工艺的成本。 重要的是,根据本发明的具有薄介电层的多层基板因此可以满足阻抗匹配的关注,并且可以减少串扰影响以保持良好的信号完整性。
