The route appointment by the anti fuse of the die/di

摘要

The program possible route designated device is offered to the semiconductor die/di in order to allot to the connection point which signal route is selected, inside. The switching matrix which at least installs one anti fuse is utilized in order the route to appoint the signal route on the semiconductor die/di selectively. For example, in order or, for feature or control of the tip/chip possibility conversion or when it is converted impossibly, for the tip/chip to operate selective, at the time of plural various socket arranging, the tip/chip can be utilized separately in order to reconstruct the pin allotment of the tip/chip. The further choices in order with process and the piggy back style which program the first tip/chip, namely to put the other tip/chip on one tip/chip, include with the process which laminates the first tip/chip in the second tip/chip. The contact pin is connected electrically, the frame outside in order to form the tip/chip which it is laminated is converted with that, and necessity of the route designated mechanism of the pin are evaded. In order the pin where the tip/chip which is laminated at the time of tip/chip constituting which it is laminated is converted, is not utilized to line up, the control pin is appointed the route.
