    Abstract: A structure/method for reducing the stress between a dielectric, passivation layer and a metallic structure comprising coating the metallic structure with a low stress modulus buffer material, and forming the dielectric passivation layer covering the low stress modulus buffer material. The low stress modulus buffer material is composed of a layer of a polymeric material selected from at least one of the group consisting of a hydrogen/alkane SQ (SilsesQuioxane) resin, polyimide, and a polymer resin. The dielectric, passivation layer is composed of at least one layer of a material selected from at least one of the group consisting of silicon oxide and silicon nitride. A protective layer is formed over the dielectric, passivation layer. The low stress modulus buffer material has a thermal coefficient of expansion between that of the metallic structure and that of the dielectric passivation layer. In particular, the dielectric passivation layer between the metallic structure and the low stress modulus buffer material has a thermal coefficient of expansion between about 5ppm/ DEG C and about 20ppm/ DEG C.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for mitigating a leakage current of a semiconductor device before catastrophic leakage current runaway occurs.SOLUTION: A leakage current shift monitor unit 20 is electrically connected to an output node of a leakage current target unit 10 and collects leakage currents from a selected target semiconductor device for two consecutive predefined temporal periods and measures the difference between the collected leakage currents. A comparator 40 receives and compares the outputs of the current shift monitor unit 20 and a reference voltage generator 30. The comparator 40 propagates an alert signal to the leakage current target unit 10 when the leakage voltage output from the leakage current shift monitor unit 20 exceeds the reference voltage, that is, a condition that indicates that the leakage current is about to approach catastrophic runaway levels. This alert signal attains leak mitigation also including a repair voltage to be applied to a gate of the target semiconductor device.

    Abstract: A method for recovery of degradation caused by avalanche hot carriers is provided that includes subjecting an idle bipolar transistor exhibiting avalanche degradation to a thermal anneal step which increases temperature of the transistor thereby recovering the avalanche degradation of the bipolar transistor. In one embodiment, the annealing source is a self-heating structure that is a Si-containing resistor that is located side by side with an emitter of the bipolar transistor. During the recovering step, the bipolar transistor including the self-heating structure is placed in the idle mode (i.e., without bias) and a current from a separate circuit is flown through the self-heating structure. In another embodiment of the present, the annealing step is a result of providing a high forward current (around the peak fT current or greater) to the bipolar transistor while operating below the avalanche condition (V CB of less than 1 V). Under the above conditions, about 40% or greater of the degradation can be recovered. In yet another embodiment of the present invention, the thermal annealing step may include a rapid thermal anneal (RTA), a furnace anneal, a laser anneal or a spike anneal.
