    • PROBLEM TO BE SOLVED: To improve the shortening of a manufacturing period and yield factor, and prevent misregistration at the time of lamination while enabling a high density wiring. SOLUTION: First, a wiring substrate 10 where a Cu post 17 is formed on a wiring layer 12 of one surface and a first stopper layer is formed at a desired position of the surroundings, a wiring substrate 20 that has a throughhole TH into which the Cu post 17 is inserted and where a connection terminal 27 is formed on a wiring layer 23 of one surface and a second stopper layer 26 that is engaged with the first stopper layer 16 functioning to suppress the misregistration in the planar direction, and a wiring substrate 30 where a connection terminal 36 is formed on a wiring layer 33 of one surface are each prepared in a separate process. Next, each wiring substrate 10, 20 and 30 is laminated to align each wiring layer so as to be mutually connected through the Cu post 17 and each connection terminal 27, 36, and a resin is filled between each substrate after each substrate is electrically connected.

    • 要解决的问题:为了提高制造周期的缩短和成品率,并且可以防止层压时的不对准,同时实现高密度布线。 解决方案:首先,在周围的期望位置处形成有在一个表面的布线层12上形成有铜柱17的第一布线基板10和具有通孔TH的布线基板20 其中插入了铜柱17,并且在一个表面的布线层23上形成有连接端子27,并且与第一阻挡层16接合的第二阻挡层26,其功能是抑制平面方向上的重合失调,以及 在一个表面的布线层33上形成连接端子36的布线基板30各自分别制备。 接下来,将每个布线基板10,20和30层叠以使每个布线层对准,以便通过Cu柱17和每个连接端子27,36相互连接,并且在每个基板电连接之后在每个基板之间填充树脂 。 版权所有(C)2008,JPO&INPIT
