    摘要: A dynamic clamp is used in conjunction with capacitors with thinner dielectric or with deep trench capacitors to solve the problem of dielectric breakdown in high stress capacitors. The dynamic clamp is realized using a two stage pump operation cycle such that, during a first stage pump cycle, a middle node of a pair of series connected capacitors is pre-charged to a supply voltage and, during a second stage pump cycle, the middle node is coupled by a boost clock. Thus, at any moment in the pump operation cycle, the voltage across the capacitors is held within a safety range.

    摘要: A method forforming a refractory metal-silicon-nitrogen capacitor in a semiconductor structure and the structure formed are described. In the method, a pre-processed semiconductor substrate is first positioned in a sputtering chamber. Ar gas is then flown into the sputtering chamber to sputter deposit a first refractory metal-silicon-nitrogen layer on the substrate from a refractory metal silicide target, or from two targets of a refractory metal and a silicon. N2 gas is then flown into the sputtering chamber until that the concentration of N2 gas in the chamber is at least 35% to sputter deposit a second refractory metal-silicon-nitrogen layer on top of the first refractory metal-silicon-nitrogen layer. The N2 gas flow is then stopped to sputter deposit a third refractory metal-silicon-nitrogen layer on top of the second refractory metal-silicon-nitrogen layer. The multi-layer stack of the refractory metal-silicon-nitrogen is then photolithographically formed into a capacitor.

    摘要: A method for determining the root causes of fail patterns in integrated circuit chips is provide wherein a known integrated circuit chip layout is used to identify a plurality of potential defects and a plurality of potential fail patterns in the integrated circuit chip. Correlations between the potential defects and the potential fail patterns that result from those defects are identified. Based on this identification, the potential fail patterns are grouped by common potential defect. An actual integrated circuit chip that is manufactured in accordance with the test layout is tested for failure patterns. These failure patterns are then compared to the groupings of potential fail patterns. When a match is found, that is when a given group of fail patterns is found in the actual integrated circuit chip, then the potential defect associated with the potential fail patterns to which the actual fail patterns are matched is identified. This defect is the root cause of the failure pattern in the actual chip.

The method nullifies the DC off-set of the signal detector so that it can detect a signal within a very narrow window. The common mode levels of the signal and reference paths are used for calibration which is done automatically by use of an embedded algorithm residing in a digital block. The calibration range and resolution are predetermined to cope with the technology, modeling, design methodology and human error.

    摘要: An interconnect structure that includes a barrier-redundancy feature which is capable of avoiding a sudden open circuit after an electromigration (EM) failure as well as a method of forming the same are provided. In accordance with the present invention, the barrier-redundancy feature is located within preselected locations within the interconnect structure including in a wide line region, a thin line region or any combination thereof. The barrier-redundancy feature includes an electrical conductive material located between, and in contact with, a conductive line diffusion barrier of a conductive line and a via diffusion barrier of an overlying via. The presence of the inventive barrier-redundancy feature creates an electrical path between the via diffusion barrier along the sidewalls of the via and the conductive line diffusion barrier along the sidewalls of the conductive line. This electrical path generated by the inventive barrier-redundancy feature can avoid a sudden open circuit resulting from EM failure at the bottom of the via. The presence of the inventive barrier-redundancy feature within an interconnect structure provides sufficient time for chip replacement or system operation.
