摘要:
Embodiments of the present invention form a weight-compensating/tuning layer on a structure (e.g., a silicon wafer with one or more layers of material (e.g., films)) having variations in its surface topology. The variations in surface topology take the form of thick and thin regions of materials. The weight-compensating/tuning layer includes narrow and wide regions corresponding to the thick and thin regions, respectively.

A method of exposing a bond pad includes: providing an integrated circuit having a bond pad, a first passivation layer overlying an area portion of the bond pad, and a second passivation layer overlying the first passivation layer; removing a portion of the second passivation layer above the area portion of the bond pad exposing an area of the first passivation layer; curing the second passivation; and etching a portion of the exposed area of the first passivation layer to expose the top surface of the bond pad. A method of coupling an integrated circuit chip to a chip package is also disclosed as is a method of probing the bond pads of an integrated circuit. A probe card is further disclosed, including a probe assembly coupled to a printed circuit board, the probe assembly having a sloped sidewall portion with a plurality of probing beams extending from the sidewall portion.

摘要:
A measurement technique and instrument using rectangular pulse trains of differing repetition rates and synchronously operated lock-in amplifiers to reject electrical noise and capture changes in resistance and capacitance of an electrical element even during a short electrical pulse applied thereto or in the presence of high levels of electrical noise. Particular applications are for electrical programming of fuses and repair of conductors by material deposition.

A method and apparatus for a linearized output driver and terminator is described. In one embodiment the method includes forming a gate electrode on a substrate, the portion of the substrate covered by the gate electrode defining a channel. The method further includes forming a first source/drain doped region on laterally opposed sides of the gate electrode in the substrate. The method also includes forming a spacer on laterally opposed sides of the gate electrode on the substrate. The method also includes forming a linearized drain contact region at a location within the first source/drain doped region sufficiently distant from the gate electrode to define a series resistor in the first source/drain doped region disposed between the gate electrode and the linearized drain contact area based on an expected resistivity of the source/drain doped region, the series resistor coupled electrically to the channel.

摘要:
An electrical device includes electrical contact pads, a supply voltage bus and an interconnection circuit. The electrical contact pads receive a supply voltage, and the bus is electrically connected to the electrical contact pads. For each electrical contact pad, the interconnection circuit forms a redundant connection between the bus and the electrical contact pad. The electrical device may include a passivation layer that includes windows to establish electrical contact between the electrical contact pads and the supply voltage bus. This window may be elongated in a path that is generally aligned with the path along which the supply voltage bus extends.
摘要:
Selectable capacitors are used to modify performance characteristics of functional circuit elements of an integrated circuit (IC). In one embodiment, the decoupling capacitors are implemented as additional or alternative mounting pads on a surface of the IC. At least one selectable capacitor is provided for each IC circuit element, such as a logic network, whose operational characteristic(s) is predicted to be and is actually identified as sub-optimal through IC testing, particularly following a process change, a mask shrink, operation of the IC at higher clock frequency, or the like. Expensive redesign is avoided by selectively coupling capacitors into the IC circuit element as needed, under control of selector logic that is responsive to control signals. Methods of operation, as well as application of the apparatus to an electronic assembly and an electronic system, are also described.
