Abstract: An anti-fuse structure that included a buried electrically conductive, e.g., metallic layer as an anti-fuse material as well as a method of forming such an anti-fuse structure are provided. According to the present invention, the inventive anti-fuse structure comprises regions of leaky dielectric between interconnects. The resistance between these original interconnects starts decreasing when two adjacent interconnects are biased and causes a time-dependent dielectric breakdown, TDDB, phenomenon to occur. Decreasing of the resistance between adjacent interconnects can also be expedited via increasing the local temperature.

Abstract: In a non-volatile semiconductor memory device and a method for manufacturing the device, each memory cell and its select Tr have the same gate insulating film as a Vcc Tr. Further, the gate electrodes of a Vpp Tr and Vcc Tr are realized by the use of a first polysilicon layer. A material such as salicide or a metal, which differs from second polysilicon (which forms a control gate layer), may be provided on the first polysilicon layer. With the above features, a non-volatile semiconductor memory device can be manufactured by reduced steps and be operated at high speed in a reliable manner.

Abstract: Prepackaged chips, such a memory chips, are vertically stacked and bonded together with their terminals aligned. The exterior lead frames are removed including that portion which extends into the packaging. The bonding wires are now exposed on the collective lateral surface of the stack. In those areas where no bonding wire was connected to the lead frame, a bare insulative surface is left. A contact layer is disposed on top of the stack and vertical metalizations defined on the stack to connect the ends of the wires to the contact layer and hence to contact pads on the top surface of the contact layer. The vertical metalizations are arranged and configured to connect all commonly shared terminals of the chips, while the control and data input/output signals of each chip are separately connected to metalizations, which are disposed in part on the bare insulative surface.
