  • Patent number: RE47600
    Abstract: A semiconductor device has a semiconductor die with a plurality of tapered bumps formed over a surface of the semiconductor die. The tapered bumps can have a non-collapsible portion and collapsible portion. A plurality of conductive traces is formed over a substrate with interconnect sites. A masking layer is formed over the substrate with openings over the conductive traces. The tapered bumps are bonded to the interconnect sites so that the tapered bumps contact the mask layer and conductive traces to form a void within the opening of the mask layer over the substrate. The substrate can be non-wettable to aid with forming the void in the opening of the masking layer. The void provides thermally induced stress relief. Alternatively, the masking layer is sufficiently thin to avoid the tapered interconnect structures contacting the mask layer.

  • Patent number: RE48002
    Abstract: An arrangement for a high resolution active matrix display includes organic emissive layers of distinct colors each deposited across continuous regions so as to include more than one pixel emissive region. Color filters are situated to partially block light from at least some of the emissive regions such that primary additive colors are transmitted from distinct subsets of pixels. The emissive layers may be deposited in alternating parallel stripes along rows or columns of the display, or may be oriented perpendicularly with respect to one another such that the emissive layers overlap in the emissive regions of at least some pixels. In some examples, red, green, and blue of pixels are arranged in regular patterns across the display and with the emissive regions for the blue pixels forming a relatively larger area of the display than either the red or green pixels.

  • Patent number: RE48996
    Abstract: A current detection module capable of differentiating and quantifying contribution to a current signal generated by a sensor in response to stimulation by a certain target source from contributions from sources other than the target source (ambient sources) is disclosed. As long as the contribution from the target source comprises a pulsed signal, the module may synchronize itself to the pulse(s) so that there is a predetermined phase relationship between the pulse(s) and functions carried out by various stages of the module. The module may be re-used to also detect and quantify contributions from ambient sources by presenting these contributions to the module as pulses that trigger synchronization of the module. To that end, a detection system disclosed herein is based on the use of such current detection module and allows mode switching where, depending on the selected mode of operation, the module is configured to perform different measurements.
