摘要: An eFuse begins with a single crystal silicon-on-insulator (SOI) structure that has a single crystal silicon layer on a first insulator layer. The single crystal silicon layer is patterned into a strip. Before or after the patterning, the single crystal silicon layer is doped with one or more impurities. At least an upper portion of the single crystal silicon layer is then silicided to form a silicided strip. In one embodiment the entire single crystal silicon strip is silicided to create a silicide strip. Second insulator(s) is/are formed on the silicide strip, so as to isolate the silicided strip from surrounding structures. Before or after forming the second insulators, the method forms electrical contacts through the second insulators to ends of the silicided strip. By utilizing a single crystal silicon strip, any form of semiconductor, such as a diode, conductor, insulator, transistor, etc. can form the underlying portion of the fuse structure. The overlying silicide material allows the fuse to act as a conductor in its unprogrammed state. However, contrary to metal or polysilicon based eFuses which only comprise an insulator in the programmed state, when the inventive eFuse is programmed (and the silicide is moved or broken) the underlying semiconductor structure operates as an active semiconductor device.

摘要: A structure and method for providing an antifuse which is closed by laser energy with an electrostatic assist. Two or more metal segments are formed over a semiconductor structure with an air gap or a porous dielectric between the metal segments. Pulsed laser energy is applied to one or more of the metal segments while a voltage potential is applied between the metal segments to create an electrostatic field. The pulsed laser energy softens the metal segment, and the electrostatic field causes the metal segments to move into contact with each other. The electrostatic field reduces the amount of laser energy which must be applied to the semiconductor structure to close the antifuse.

摘要: A method for fabricating a connector structure for interconnecting integrated circuit chips. The method includes the steps of patterning, masking and etching a substrate to form protrusions on the top and/or bottom surfaces of the substrate. Then the protrusions are preferentially etched to form truncated protrusions. An integrated circuit chip having pads on its surface is then joined to the top and/or bottom sides of the substrate. The protrusions and pads are coated with an electrically conductive metal. The substrate and the integrated circuit chips are joined and aligned together such that the truncated protrusions mate with the pads. Metal-coated vias are formed through the substrate to electrically connect the integrated circuit chips on the surfaces of the substrate.
