  • Patent number: 9331042
    Abstract: A plurality of protruding electrodes of a semiconductor chip are in contact with a plurality of electrodes formed on a semiconductor substrate, via a plurality of solder sections. In this state, the solder sections are melted so as to form a plurality of solder bonding sections joined to the protruding electrodes of the semiconductor chip and the electrodes of the semiconductor substrate. Moreover, a distance between a part of the semiconductor chip and the semiconductor substrate is larger than a distance between the other part of the semiconductor chip and the semiconductor substrate, extending at least some of the solder bonding sections. Thus, the solder bonding sections vary in height. Holes are then formed at least in a solder bonding section having a maximum height out of the solder bonding sections. After that, the solder bonding sections are solidified.

  • Publication number: 20150286357
    Abstract: Methods, systems, and computer-readable media for providing snap navigation in a scrollable list are presented. Certain items of the content items in the scrollable list may represent natural or desirable breakpoints for scrolling through the list. As a list view scrolls through the scrollable list in response to user input, the list view may suspend scrolling when it reaches a breakpoint content item. In some embodiments, a computing device may determine that a given content item represents a breakpoint in the scrollable list based on a breakpoint rule. The breakpoint rule may be based on any suitable criteria for identifying the content item as a breakpoint for scrolling the list. For example, the breakpoint rule may be based on the content of the content item or a category of the content item.
