摘要： Anti-reverse engineering techniques are provided. In one aspect, a method for forming at least one feature in an insulating layer is provided. The method comprises the following steps. Ions are selectively implanted in the insulating layer so as to form at least one implant region within the insulating layer, the implanted ions being configured to alter an etch rate through the insulating layer within the implant region. The insulating layer is etched to, at the same time, form at least one void both within the implant region and outside of the implant region, wherein the etch rate through the insulating layer within the implant region is different from an etch rate through the insulating layer outside of the implant region. The void is filled with at least one conductor material to form the feature in the insulating layer.

摘要： A modularized capacitor array includes a plurality of capacitor modules. Each capacitor module includes a capacitor and a switching device that is configured to electrically disconnect the capacitor. The switching device includes a sensing unit configured to detect the level of leakage of the capacitor so that the switching device disconnects the capacitor electrically if the leakage current exceeds a predetermined level. Each capacitor module can include a single capacitor plate, two capacitor plates, or more than two capacitor plates. The leakage sensors and switching devices are employed to electrically disconnect any capacitor module of the capacitor array that becomes leaky, thereby protecting the capacitor array from excessive electrical leakage.

摘要： A system is provided for detecting a fault in a signal transmission path. In one embodiment, the system can include a variable amplitude signal attenuator which is operable to modify an input signal by variably attenuating a signal voltage swing of the input signal. Desirably, the input signal is attenuated only when transitioning from a high signal voltage level towards a low signal voltage level d variably, such that a larger high-to-low signal voltage swing is attenuated more than a smaller high-to-low signal voltage swing. Desirably, a comparator, which may apply hysteresis to the output signals, may detect a crossing of a reference voltage level by the modified input signal. In this way, when the comparator does not detect an expected crossing of the reference voltage level by the modified input signal, a determination can be made that a fault exists in the signal transmission path.

摘要： An epitaxial semiconductor layer or a stack of a silicon germanium alloy layer and an epitaxial strained silicon layer is formed on outer sidewalls of a porous silicon portion on a substrate. The porous silicon portion and any silicon germanium alloy material are removed and a semitubular epitaxial semiconductor structure in a three-walled configuration is formed. A semitubular field effect transistor comprising inner and outer gate dielectric layers, an inner gate electrode, an outer gate electrode, and source and drain regions is formed on the semitubular epitaxial semiconductor structure. The semitubular field effect transistor may operate as an SOI transistor with a tighter channel control through the inner and outer gate electrodes, or as a memory device storing electrical charges in the body region within the semitubular epitaxial semiconductor structure.

摘要： Aspects of the invention relate to a programmable heavy-ion sensing device for accelerated DRAM soft error detection. Design of a DRAM-based alpha particle sensing apparatus is preferred to be used as an accelerated on-chip SER test vehicle. The sensing apparatus is provided with programmable sensing margin, refresh rate, and supply voltage to achieve various degree of SER sensitivity.

摘要： In a method for performing equalization of a communication system, a predetermined signal can be transmitted from a transmitter unit to a receiver unit in a downchannel direction on a transmission line, for example as a pair of differential signals which simultaneously transition in opposite directions on respective signal conductors of the transmission line. At the receiver unit, an eye opening of the signal received from the transmission line can be analyzed to determine equalization information. Equalization information can be transmitted from the receiver unit to the transmitter unit in an upchannel direction on the transmission line and be received at the transmitter unit. Using received equalization information, a transmission characteristic of the transmitter unit can be adjusted.
