Methods and apparatus for performing timing driven hardware emulation

Номер: US20190005174A1
Автор: Mohamed Farag
Принадлежит: Intel Corp

Programmable integrated circuits may be used to perform hardware emulation of an application-specific integrated circuit (ASIC) design. The ASIC design may be loaded onto the programmable integrated circuit. During hardware emulation operations, an emulation host may be used to coordinate testing of the DUT on the programmable device. Circuit design tools may be used to extract parasitics from the ASIC design, compute low-level interconnect delays, convert the interconnect delays to higher-level port-to-port delays, convert the port-to-port delays to timing constraints, and generate corresponding configuration data for programming the programmable integrated circuit to emulate the ASIC design. The programmable integrated circuit may then be tested for functional and performance integrity.

Multiple planes in the sample are exposed from a single field of view for contact by the electrical probe. The sample is milled at a non-orthogonal angle to expose different layers as sloped surfaces. The sloped edges of multiple parallel conductor planes provide access from above to multiple levels. The planes can be accessed, for example, for use in contact with an electrical probe to apply or sense a voltage. The level of the exposed exposed layer can be confirmed, for example, by counting down the exposed layers from the sample surface, because non-orthogonal mill makes all layers visible from above. Alternatively, the sample can be milled orthogonal to the surface and then be inclined and / or rotated, providing access to multiple levels of the device. In order to provide electrical access to the area while minimizing damage to the area of interest, the milling is preferably performed far from the area of interest.

Endpoint detection for thinning of silicon of a flip chip bonded integrated circuit

Номер: US6285036B1
Принадлежит: Advanced Micro Devices Inc

A system for determining the endpoint associated with removing silicon from the backside of a flip chip type die includes a tool for removing silicon and a light source for directing light to the backside of the die. An electrical measuring apparatus, such as a voltmeter, ammeter or oscilloscope, is attached across the output pins of a package to which the die is attached. The light or ions directed toward the backside of the die induce a current in the devices formed in the semiconductor. The value of the current or voltage output depends on the thickness of material between the endpoint on the backside of the die and the devices in the epitaxial layer of the die. The induced signal can be monitored to determine the thickness. Silicon can be removed globally until the thickness is reasonable such that a local thinning tool can be used to remove silicon to get to the area of interest in a reasonable amount of time. The induced current can be monitored during local thinning. A viewing mechanism such as infrared microscopy can be used to locate the specific device or devices of interest in the epitaxial layer of the die. The viewing mechanism is also used to determine where localized thinning will occur.

Failure analysis methods and systems

Номер: CA2532959A1
Автор: Gregory B. Anderson

A method and system for exposing the delicate structures of a device encapsulated in a mold compound such as an integrated circuit (IC). A laser is used to ablate the mold compound and thus remove it, exposing the underlying structure. The laser beam can be steered in a desired raster pattern onto the surface of the device or the device can be moved in the desired pattern relative to the laser beam. Spectral analysis can be performed on the laser plume emitted by the ablation process in order to determine the composition of the ablated material. Thus, in addition to exposing defects in the underlying structure, the system can also be used to analyze the encapsulating material in order to determine whether it contained any defects or anomalies. A system for precisely cutting a circuit board or an IC in a user-selected pattern is also described. The system directs a laser along a path that a user can specify using a graphical interface.

A second structure contains a plurality of second metallization components. The first structure is disposed over a first side of the substrate. The second structure is disposed over a second side of the substrate opposite the first side. A trench extends through the DUT board and extends partially into the IC die from the second side. A signal detection tool is configured to detect electrical or optical signals generated by the IC die.

A method for cleaning a contact pad of a microstructure or device to be tested when it is in electric contact with a measure apparatus, being obtained by electrically contacting a flexible probe with said contact pad. The method includes mechanically engaging a free end of the flexible probe in a manner that sticks the free end in the pad; and laterally flexing, by means of a tip charge, the flexible probe in a manner that keeps the free end stuck in the pad, so as to locally dig into a covering layer of the pad and realize a localized crushing thereof.

Methods and structures for semiconductor device testing

Номер: US11982709B2
Принадлежит: Yangtze Memory Technologies Co Ltd

A structure for performing analysis includes a first opening formed on a back side of a substrate and passing through the substrate, a second opening connected with a bottom of the first opening and penetrating into a first dielectric layer formed on a front side of the substrate, a first conductive layer formed on a sidewall of the second opening and a contact element in the first dielectric layer, and a second conductive layer formed on a second dielectric layer. The first conductive layer contacts the second conductive layer electrically.
