    摘要: A plurality of fuses of different types, each type of fuse serving a specific purpose are positioned on a semiconductor integrated circuit wafer, wherein activating one type of fuse does not incapacitate fuses of a different type. Fuses of the first type, e.g., laser activated fuses, are primarily used for repairing defects at the wafer level, whereas fuses of the second type, e.g., electrically activated fuses, are used for repairing defects found after mounting the IC chips on a module and stressing the module at burn-in test. Defects at the module level typically are single cell failures which are cured by the electrically programmed fuses to activate module level redundancies.

    摘要: A defect management engine (DME) for memories integrates a plurality of redundancy data cells and a plurality of redundancy address cells in the same array. The redundancy data cells are used for replacing defective cells in the memories. The redundancy address cells store the addresses of the defective cells. The memories are preferably sub-divided into a plurality of domains. A plurality of defective cells in each domain are supported by a plurality of repair units, each consisting of one or more redundancy data bits and redundancy address bits in the DME. When one or more data bits are read from a domain in the memory, the corresponding wordline in the DME simultaneously activates a plurality of repair units coupling to the wordline (self-contained domain selection). The redundancy data bits and the redundancy address bits are also read from the redundancy data cells and redundancy address cells, respectively. The DME logic detects whether or not the redundancy address bits match or do not match the address inputs of each repair unit (self contained redundancy match detection). This couples either redundancy data bits from the DME (i.e., a matching condition) or the data bits from the domain in the memories (i.e., a no match condition) to the corresponding DQ (self-contained redundancy replacement). The DME enables an integrated redundancy means (self-contained domain selection, self-contained redundancy match detection, and self-contained redundancy replacement). Single bit replacement, multi-bit replacement, line replacement, and variable bit size replacement are discussed. Finally, an extension of the DME concept to a memory system is also discussed.

    摘要: In a bonding station the parts of the apparatus to be bonded are retained at a thermal bias temperature at a permitted level and a thermal check valve interface is provided between the bonding location and the part of the station that would serve as a conduction heat sink, thereby thermally insulating other uninvolved parts of the structure and and confining the bonding heat to the bonding region. Such confinement reduces the dwell time that the bond must remain at the bonding temperature. The bonding station has a number of features: the parts to be bonded are maintained on a support member that is provided with a heat biasing capability that can establish the assembly at a specified temperature; a retention capability, such as the use of vacuum, is provided to maintain registration and thermal contact of the part with the support; and a thermal check valve capability is provided to control the rate of heat flow through the support member so that locallized heat is controlled in dissipation.
