  • Patent number: 9786643
    Abstract: Methods of protecting semiconductor devices may involve forming trenches in streets between stacks of semiconductor dice on regions of a semiconductor wafer. A protective material may be positioned between the die stacks and in the trenches, after which the wafer is thinned from a side opposite the die stacks to expose the protective material in the trenches. Semiconductor devices comprising stacks of dice and corresponding base semiconductor dice comprising wafer regions are separated from one another by cutting through the protective material along the streets and in the trenches. The protective material covers at least sides of each die stack as well as side surfaces of the corresponding base semiconductor die.

  • Patent number: 9786612
    Abstract: Wafer-level methods of processing semiconductor devices may involve forming grooves partially through a molding material, the molding material located in streets and at least surrounding stacks of semiconductor dice located on a wafer. Wafer-level methods of preparing semiconductor devices may involve attaching a wafer to a carrier substrate and forming stacks of laterally spaced semiconductor dice on die locations of the wafer. Molding material may be disposed over the die stacks on a surface of the wafer to at least surround the stacks of semiconductor dice with the molding material. Grooves may be formed in the molding material by partially cutting through the molding material between at least some of the stacks of semiconductor dice along streets between the die stacks. The resulting wafer-level assembly may then, when exposed to elevated temperatures during, for example, debonding the wafer from a carrier, exhibit reduced propensity for warping.

  • Patent number: 9765310
    Abstract: Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.

  • Publication number: 20170219343
    Abstract: The present invention provides a Fabry-Perot sensor for measuring inclination. Wherein the present inclinometer is fixed on a static detected object in application use, the mass block is flexibly connected to the top plate, thus the line between the center of gravity of the mass block and the connecting point on the top plate is perpendicular to the horizontal plane; a Fabry-Perot cavity is formed between the reflecting surface disposed at one end of the mass block and the end of the optic fiber. The detected object will be in a static state after tilting, the line between the center of gravity of the mass block and its connecting point on the top plate is still perpendicular to the level plane and the F-P cavity length will have a variation. Then the change of cavity length can be measured in accordance with the Fabry-Perot principle, thereby the tilting angle of the mass block is able to be further measured. Then the tilting angle is also the inclination of the detected object.
