    摘要: An integrated memory cube structure and method of fabrication wherein stacked semiconductor memory chips are integrated by a controlling logic chip such that a more powerful memory architecture is defined with the functional appearance of a single, higher level memory chip. A memory/logic cube is formed having N memory chips and at least one logic chip, with each memory chip of the cube having M memory devices. The controlling logic chip coordinates external communication with the N memory chips such that a single memory chip architecture with N.times.M memory devices appears at the cube's I/O pins. A corresponding fabrication technique includes an approach for facilitating metallization patterning on the side surface of the memory subunit.

    摘要: Wafer test and burn-in is accomplished with state machine or programmable test engines located on the wafer being tested. Each test engine requires less than 10 connections and each test engine can be connected to a plurality of chips, such as a row or a column of chips on the wafer. Thus, the number of pads of the wafer that must be connected for test is substantially reduced while a large degree of parallel testing is still provided. The test engines also permit on-wafer allocation of redundancy in parallel so that failing chips can be repaired after burn-in is complete. In addition, the programmable test engines can have their code altered so test programs can be modified to account for new information after the wafer has been fabricated. The test engines are used during burn-in to provide high frequency write signals to DRAM arrays that provide a higher effective voltage to the arrays, lowering the time required for burn-in. Connections to the wafer and between test engines and chips are provided along a membrane attached to the wafer. Membrane connectors can be formed or opened after the membrane is connected to the wafer so shorted chips can be disconnected. Preferably the membrane remains on the wafer after test, burn-in and dicing to provide a chip scale package. Thus, the very high cost of TCE matched materials, such as glass ceramic contactors, for wafer burn-in is avoided while providing benefit beyond test and burn-in for packaging.

    摘要: A burn-in process is provided for a memory array having redundant bits and addressable storage locations. The burn-in process includes the steps of raising the temperature of the memory array to a pre-determined temperature, testing all bits in the array, detecting faulty bits and operable bits, replacing faulty bits with redundant operable bits, correcting any defects in the array in-situ, and lowering the temperature of the memory array to ambient temperature to complete the burn-in process. An apparatus for carrying out the above process is provided that includes a test circuit for generating a test pattern and for applying the test pattern to the memory array so as to test all bits within the memory array. A comparison circuit, coupled to the test circuit and adapted to couple to the memory array, compares an actual response and an expected response of the memory array to the test pattern and detects faulty and operable bits based thereon. A failed address buffer register, coupled to the comparison circuit and to the test circuit, stores an address of each addressable storage location that has a faulty bit. Sparing control logic, coupled to the failed address buffer register and adapted to couple to the memory array, reads out each address stored by the failed address buffer register and replaces each faulty bit with a redundant operable bit.

    摘要: A vertical Field Effect Transistor (FET) that may be an N-type FET (NFET) or a P-type FET (PFET); a multi-device vertical structure that may be two or more NFETs or two or more PFETS; logic gates including at least one vertical FET or at least one multi-device vertical; a Static Random Access Memory (SRAM) cell and array including at least one vertical FET; a memory array including at least one such SRAM cell; and the process of forming the vertical FET structure, the vertical multi-device (multi-FET) structure, the logic gates and the SRAM cell. The vertical FETs are epitaxially grown layered stacks of NPN or PNP with the side of a polysilicon gate layer adjacent the device's channel layer. The multi-FET structure may be formed by forming sides of two or more gates adjacent to the same channel layer or, by forming multiple channel layers in the same stack, e.g., PNPNP or NPNPN, each with its own gate, i.e., the side of a polysilicon gate layer. The SRAM cell may be radiation hardened by selectively thickening gate layers to increase storage node capacitance, providing high resistance cell wiring or by including a multi-layered gate oxide layer of NO or ONO, or by any combination thereof.
