Abstract: An apparatus and method for receiving a signal waveform representing a signal-under-test (SUT), and a noise waveform representing noise measured in the absence of the SUT. An environment waveform is derived from the noise waveform and the signal waveform, and a jitter spectrum is computed from the environment waveform. An environment spur is detected, where the environment spur includes a spur in the jitter spectrum of the environment waveform. A jitter spectrum of the signal waveform is computed, and one or more signal spurs are detected, where the one or more signal spurs include one or more spurs in the jitter spectrum of the signal waveform. A measure of jitter for the SUT is derived from the one or more signal spurs after reducing the presence of at least one of the one or more signal spurs in response to detecting the environment spur.

Abstract: A clock timing signal derived from a clock timing source is converted into samples obtained at a plurality of sample times, each sample representing an amplitude of a clock timing signal at a corresponding sample time. A time-domain histogram of deterministic jitter (DJ) is derived from a plurality of the samples. A set of measurement-based data that is not derived from the samples is also received, from which a time-domain histogram of random jitter (RJ) is derived. A jitter measurement is determined by convolving the time-domain histograms of DJ and RJ. Tangible non-transitory computer-readable storage devices can contain instructions that when carried out on processor(s) carry out the above process An apparatus has a clock sampling unit and a signal analyzer to derive the measure of jitter.

Abstract: A method for fabricating a semiconducting device on a substrate, where the improvement includes forming a strained silicon germanium channel layer on the substrate. A gate insulation layer is formed on top of the strained silicon germanium channel layer, at a temperature that does not exceed about eight hundred centigrade. A gate electrode is formed on top of the gate insulation layer, and the gate electrode is patterned. A low dose drain dopant is impregnated into the substrate, and activated with a first laser anneal. A source-drain dopant is impregnated into the substrate, and activated with a second laser anneal. After the step of activating the low dose drain dopant with the first laser anneal, an insulating layer is formed around the gate electrode, at a temperature that does not exceed about eight hundred centigrade, and a spacer is formed around the gate electrode. The spacer is formed of a material that is reflective to the second laser anneal.

Abstract: A severable horizontal portion of a fuse link is formed relative to a vertically configured structure in an IC to promote separation of the severable portion upon applying energy from a laser beam. The vertically configured structure may be a reduced vertical thickness of the severable portion, an elevated lower surface of the severable portion above adjoining portions of the fuse link, a protrusion which supports the severable portion at a height greater than a height of the adjoining portions of the fuse link, flowing the melted severable portion down sloped surfaces away from a break point, and a propellent material beneath the severable portion which explodes to ablate the severable portion.

Abstract: A method for fabricating an SRAM device having a standard well tub, where an additional well tub is deposited within the standard well tub. In this manner, the dopant concentration is increased in the well area of the SRAM device, which increases both the isolation punchthrough tolerance and the SER immunity of the device. The additional well tub is deposited to a depth that is shallower than the standard well tub. The additional well tub is deposited using an ion implantation process using the same mask set as that used for the threshold voltage adjustment deposition. Thus, no additional mask layer is required to deposit the additional well tub, and the all of the expenses normally associated with an additional mask layer are avoided.

Abstract: Provided are a self-aligned semiconductor fuse structure, a method of making such a fuse structure, and apparatuses incorporating such a fuse structure. The fuse break point, that point at which the electrical link of which the fuse is part is severed by a laser beam, is self-aligned by the use of photolithographically patterned anti-reflective dielectric coatings. The self-alignment allows the size location of the break point to be less sensitive to the laser beam size and alignment. This has several advantages including allowing photolithographic control and effective size reduction of the laser spot irradiating the fuse material and surrounding structure. This permits reduced fuse pitch, increasing density and the efficiency of use of chip area, and results in reduced thermal exposure, which causes less damage to chip. In addition, laser alignment is less critical and therefore less timely, which increases throughput in fabrication.

The fuse break point, that point at which the electrical link of which the fuse is part is severed by a laser beam, is self-aligned by the use of photolithographically patterned dielectric and a heat sink material. The self-alignment allows the size and location of the break point to be more forgiving of the laser beam size and alignment. This has several advantages, including allowing photolithographic control and effective size reduction of the laser spot irradiating the fuse material and surrounding structure. This permits reduced fuse pitch, increasing density and the efficiency of use of chip area, and results in reduced thermal exposure, which causes less damage to chip. In addition, laser alignment is less critical and therefore less time-consuming, which increases throughput in fabrication.

Abstract: Provided is a method of forming a silicide layer on the top and sidewall surfaces of a polysilicon gate/interconnect in a MOS transistor and on the exposed surfaces of the source and drain regions of the transistor. Devices produced according to the present invention may have different types of silicide formed on their gate and their source/drain electrodes. The invention achieves the advantages of silicide encapsulation of a polysilicon gate in an MOS transistor while also providing silicidation of the source/drain regions of the transistor, thereby reducing electrode resistivity in the transistor and interconnect.

Abstract: A method of forming a supersaturated layer on a semiconductor device, where an initial phase layer is deposited on the semiconductor device. The initial phase layer has a solid phase dopant saturation level and a liquid phase dopant saturation level, where the liquid phase dopant saturation level is greater than the solid phase dopant saturation level. A concentration of a dopant is impregnated within the initial phase layers, where the concentration of the dopant is greater than the solid phase dopant saturation level and no more than about the liquid phase dopant saturation level. The initial phase layer is annealed, without appreciably heating the semiconductor device, using an amount of energy that is high enough to liquefy the initial phase layer over a melt duration. This dissolves the dopant in the liquefied initial phase layer. The amount of energy is low enough to not appreciably gasify or ablate the initial phase layer.

Abstract: A process is described for forming self-aligned contacts to an MOS device on an integrated circuit structure characterized by the simultaneous formation of the metal silicide gate portion and the metal silicide source/drain portions. The process comprises forming a gate oxide layer on a silicon substrate, forming a polysilicon gate electrode layer over the gate oxide layer, and forming a layer of a first insulation material over the polysilicon gate electrode layer. Metal silicide is simultaneously formed on the exposed surface of the polysilicon gate electrode and over the exposed portions of the silicon substrate. Source/drain regions are formed in the silicon substrate, either before or after formation of the metal silicide over the exposed portions of the silicon substrate, whereby the metal silicide portions on the substrate above the source/drain regions are in electrical communication with the source/drain regions.
