摘要:
Provided is a semiconductor memory module allowing a filling member formed between a module substrate and memory chips mounted on the module substrate to completely fill the space between the module substrate and the memory chips. According to embodiments of the present invention, the semiconductor memory module includes a module substrate having at least one memory chip mounted on the substrate such that its edges are oblique to major and minor axes bisecting the module substrate. The oblique orientation allows for an improved opening between memory chips formed on the substrate so that the filling member may be properly formed between the module substrate and the memory chips to prevent voids where the filling member is not formed.

A multilayered circuit substrate and a semiconductor package using the multilayered circuit substrate are provided to increase the number of bonding pads arranged on the circuit substrate without reducing the pitch of the bonding pads, and to further increase the routing feasibility of high speed signals by the use of signal wirings instead of vias. An embodiment may include bonding pads provided on different layers, in which the bonding pads arranged on one layer are staggered with the bonding pad arranged on another layer. Ball lands may be connected to the bonding pads using wirings wherein the bonding pads connected to the signal wirings may be provided on the same layer as the corresponding ball lands.
