Abstract
An object of the present invention is to improve the degree of freedom in the wiring design of a wiring substrate configuring a semiconductor device. Lands having an NSMD structure and a land-on-through-hole structure are arranged at positions not overlapping with a plurality of leads arranged on a chip loading surface of a wiring substrate in transparent plan view on the outer peripheral side of a mounting surface of the wiring substrate configuring a semiconductor device having a BGA package structure. On the other hand, land parts having the NSMD structure and to which lead-out wiring parts are connected are arranged at positions overlapping with the leads arranged on the chip loading surface of the wiring substrate in transparent plan view on the inner side than the group of lands in the mounting surface of the wiring substrate.
