摘要: An integrated circuit assembly has pads of a chip electrically connected to pads of a substrate with rolling metal balls. A pliable material bonds the balls in movable contact with pads of the chip and substrate. Because the balls are relatively free to move, thermal expansion differences that would ordinarily cause enormous stresses in the attached joints of the prior art, simply cause rolling of the balls of the present invention, avoiding thermal stress altogether. Reliability of the connections is substantially improved as compared with C4 solder bumps, and chips can be safely directly mounted to such substrates as PC boards, despite substantial thermal mismatch.

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: An off-chip driver circuit including an enhancement PFET, a depletion PFET, a depletion NFET and an enhancement NFET connected in series. The large enhancement PFET and large enhancement NFET turn off the OCD in tri-state and to turn off the unused half of the OCD to prevent overlap current when driving a ‘0’ or a ‘1’. A first gate signal is applied to the gate of the enhancement PFET and a second gate signal is applied to the enhancement NFET. A fixed voltage is connected to the gate of the depletion NFET and ground to gate of the depletion PFET. An output signal is obtained from a node between the depletion PFET and depletion NFET devices. In another embodiment, a reflection/overshoot sensor 60 is added. The output of sensor is connected to the body of a depletion PFET and an NFET. The feedback from sensor is such that the threshold voltage of the depletion devices are made more positive if the sensor detects that the output is being over-driven. A more positive threshold voltage will reduce the driver's IDS, but leaves the device in the linear mode.

摘要: Use of different materials for different conductive films forming plates or electrodes of one or more capacitors formed in a trench in a body of semiconductor materials allow connections to be made selectively to the plates. The films may be undercut by different etchants at respective connection apertures to avoid formation of connections or connections made by doped polysilicon of different conductivities forming connections to some plates of similarly doped polysilicon and blocking diode junctions with oppositely doped polysilicon. The blocking diodes may include a compensation implant to adjust reverse breakdown characteristics and provide transient and electrostatic discharge protection.

摘要: A plurality of semiconductor devices are provided on a carrier for testing or burning-in. The carrier is then cut up to provide single chip-on-carrier components or multi-chip-on-carrier components. The carrier is used as a first level package for each chip. Thus, the carrier serves a dual purpose for test and burn-in and for packaging. A lead reduction mechanism, such as a built-in self-test engine, can be provided on each chip or on the carrier and is connected to contacts of the carrier for the testing and burn-in steps. The final package after cutting includes at least one known good die and may include an array of chips on the carrier, such as a SIMM or a DIMM. The final package can also be a stack of chips each mounted on a separate carrier. The carriers of the stack are connected to each other through a substrate mounted along a side face of the stack that is electrically connected to a line of pads along an edge of each carrier.

摘要: A gap conductor structure for an integrated electronic circuit that may function as an electronic fuse device or as a low capacitance inter level signal line is integrated as part of the semi-conductor chip wiring. The gap conducting structure includes one or more air gap regions of predefined volume that fully or partially exposes a length of interlevel conductor layer in an IC. Alternately, the air gap region may wholly located within the dielectric region below a corresponding conductor and separated by insulator. When functioning as a fuse, the gap region acts to reduce thermal conductivity away from the exposed portion of the conductor enabling generation of higher heat currents in the conducting line with lower applied voltages sufficient to melt a part of the conducting line. The presence of gaps, and hence, the fuses, are scalable and may be tailored to the capacity of currents they must carry with the characteristics of the fuses defined by a circuit designer. Furthermore, conducting structures completely or partially exposed in the air gap may function as low capacitance minimum delay transmission lines.
