Abstract: A ball grid array assembly includes a package cover that encapsulates a die and a portion of a substrate to which the die is attached, including an edge of the substrate. Encapsulation of the substrate edge by the cover reduces penetration of moisture or other contaminants into the substrate. The cover includes a rib that extends to contact a circuit board to which the ball grid array assembly is connected. With such a rib, planarity between the circuit board and the substrate is maintained during soldering.

Abstract: A mechanism and methodology is provided for performing high-throughput thin-film experimentation with the use and integration of a heater. A single flange assembly contains an automated two-dimensional shutter system (which provides variable masking schemes for spatially selective shadow deposition) and a rotatable (indexed) chip/wafer/substrate heater. The automated two-dimensional shutter system comprises two shutter plate mounts that move in two perpendicular (x and y) directions, so that mounted shutters overlap with each other in certain regions. The substrate heater can be used in the gradient temperature mode or uniform temperature mode. The shutter plates and the heater plate are detachable and exchangeable from experiment to experiment in order to minimize cross contamination of materials.

Abstract: A method and apparatus for performing intra-tool monitoring and control within a multi-step processing system. The method monitors the processing of a workpiece as the workpiece is processed by independently operating processing tools and produces control parameters for the various independently operating processing tools to optimize the processing of the workpiece. More specifically, the apparatus provides a metrology station located between each of a plurality of semiconductor wafer processing tools such that measurements can be made on wafers as they are passed from one tool to another providing intra tool monitoring. The data collected by the metrology station is coupled to a metrology data analyzer, which determines whether any of the plurality of wafer processing tools should be adjusted to improve the processing of the overall wafer.

Then, a mesa-etching process is performed to form a first top surface and a second top surface on the light emitting diode epitaxy structure for respectively exposing an n-type layer and a p-type layer in the light emitting diode epitaxy structure. Next, a metal reflective layer and a barrier layer are formed on the light emitting diode epitaxy structure in turn, and electrodes are finally fabricated on the barrier layer.
Abstract: According to some embodiments, a fin type active region is formed under an exposure state of sidewalls on a semiconductor substrate. A gate insulation layer is formed on an upper part of the active region and on the sidewalls, and a device isolation film surrounds the active region to an upper height of the active region. The sidewalls are partially exposed by an opening part formed on the device isolation film. The opening part is filled with a conductive layer that partially covers the upper part of the active region, forming a gate electrode. Source and drain regions are on a portion of the active region where the gate electrode is not. The gate electrode may be easily separated and problems causable by etch by-product can be substantially reduced, and a leakage current of channel region and an electric field concentration onto an edge portion can be prevented.

Abstract: In a semiconductor device for generating complementary PWM signals for, for example, controlling an inverter, a dead time is flexibly added by using a simple architecture. A dead time addition unit adds time elapsing until a value of a timer reaches a set value of a register as a first dead time at a rise of a first PWM signal. On the other hand, time elapsing until the value of the timer reaches a set value of another register is added as a second dead time at a rise of a second PWM signal.

Abstract: The present invention uses in situ scatterometry to determine if a defect (e.g., photoresist erosion, photoresist bending and pattern collapse) is present on a wafer. In one embodiment, in situ scatterometry is used to detect a pattern integrity defect associated with the layer of photoresist. In situ scatterometry produces diffraction data associated with the thickness of the photoresist patterned mask. This data is compared to a model of diffraction data associated with a suitable photoresist thickness. If the measured diffraction data is within an acceptable range, the next step of the photolithography process is carried out. However, if the measured thickness is outside of the suitable range, a defect is detected, and the wafer may be sent for re-working or re-patterned prior to main etch, thereby preventing unnecessary wafer scrap.

Abstract: Bright and dark field imaging operations in an optical inspection system occur along substantially the same optical path using the same light source by producing either a circular or an annular laser beam. Multiple beam splitting is achieved through the use of a diffractive optical element having uniform diffraction efficiency. A confocal arrangement for bright field and dark field imaging can be applied with multiple beam scanning for suppressing the signal from under-layers. A scan direction not perpendicular to the direction of movement of a target provides for improved die-to-die comparisons.
