Abstract:
A method of forming a heat spreader ball grid array package, and the resultant heat spreader ball grid array package, comprising the following steps. A semiconductor chip affixed to a ball grid substrate is provided. The semiconductor chip over the ball grid substrate is encased with a molding compound. A heat spreader is mounted over the ball grid substrate and spaced apart from the molding compound to form a gap. Thermal grease is placed into the gap, at least between the heat spreader and the molding compound, to form the heat spreader ball grid array package. It is also possible to place thermal grease over the molding compound and then mounting the heat spreader over the ball grid substrate.

Abstract:
Novel methods for reducing shear stress applied to solder bumps on a flip chip. The methods are particularly applicable to reducing temperature-induced shear stress on solder bumps located adjacent to an empty space on a flip chip during high-temperature testing of the chip. According to a first embodiment, the method includes providing an anchoring solder bump in each empty space on the flip chip. The anchoring solder bumps impart additional structural integrity to the flip chip and prevent shear-induced detachment of solder bumps from the flip chip, particularly those solder bumps located adjacent to each anchoring solder bump. According to a second embodiment, the method includes providing an anchoring solder bump in the empty space and then connecting the anchoring solder bump to an adjacent solder bump on the chip using a solder bridge.
Abstract:
The present invention relates to a table structure that can be converted into bed or table according to user's needs. Wherein a base frame of the present invention is respectively provided with a bed having two L-shape side frames and a table having two side shelves. The two side shelves of the table are connected to the base frame through spiral arms, by virtue of the pivotal connection between the L-shape side frames and the side shelves, the bed can be positioned respectively in a horizontal manner or in a vertical manner. Through the spiral arms, the table can be lowered down or raised up relative to the bed, such that the device of the present invention can be converted into a bed or a table as desired.
Abstract:
A composition of a fragrant ink, at least comprising a microcapsule compound, a colorant, a media, a dispersing agent, and an emulsifier, and a preparation method thereof are disclosed. The microcapsule compound encapsulates a fragrant agent for providing the fragrant ink with fragrance. The colorant provides the fragrant ink with at least one color. The media is used as a solvent. The dispersing agent is for evenly dispersing the microcapsule compound in the media. The emulsifier emulsifies the fragrant agent released from the microcapsule compound and evenly disperses the fragrant agent in the media.
Abstract:
A novel approach to detection of leakage site detection for BGA chips. The invention prevents damaging the semiconductor circuit that is a problem during conventional preparation for backside leakage detection for BGA chips. The invention teaches removing the backside from the BGA device and separating the BGA device into two parts. The back surface of the molded part within which the BGA chip is embedded remains undamaged within the scope of the present invention and can be electrically accessed to perform BGA die analysis.
Abstract:
A conversion method of applications of mobile devices is provided. The method includes the steps of obtaining a device feature information and a platform information of a mobile device, modifying, by a convertor, a first description data of a first application according to the obtained device feature information and platform information, and converting the modified first application to a second application in which the first application is represented by a platform-neutral language and at least includes the first description data for describing the interaction design of a user interface, and the second application is represented by a language corresponding to the platform information and can be executed on the mobile device.
Abstract:
An integrated circuit includes a substrate having a bonding pad region and a non-bonding pad region. A relatively large via, called a “big via,” is formed on the substrate in the bonding region. The big via has a first dimension in a top view toward the substrate. The integrated circuit also includes a plurality of vias formed on the substrate in the non-bonding region. The plurality of vias each have a second dimension in the top view, the second dimension being substantially less than the first dimension.
Abstract:
A system and method for forming a semiconductor device is provided. An embodiment comprises forming a silicide region on a substrate along with a transition region between the silicide region and the substrate. The thickness of the silicide precursor material layer along with the annealing conditions are controlled such that there is a larger ratio of one atomic species within the transition region than another atomic species, thereby increasing the hole mobility within the transition region.
Abstract:
