20080293232 | Standoff Height Improvement for Bumping Technology Using Solder Resist - A system to support a die includes a substrate. A solder resist is disposed over the substrate. A first solder bump is disposed in the solder resist to provide electrical connectivity through the solder resist to the substrate. A second solder bump is formed over the solder resist to correspond with a peripheral edge or a corner of the die. The second solder bump provides standoff height physical support to the die. | 11-27-2008 |
20100022050 | Standoff Height Improvement for Bumping Technology Using Solder Resist - A semiconductor device is made by disposing a film layer over a substrate having first conductive layer. An opening is formed in the film layer to expose the first conductive layer. A second conductive layer is formed over the first conductive layer. A first bump is formed over the second conductive layer which promotes reflow of the first bump at a eutectic temperature. A standoff bump is formed on the film layer around a perimeter of the substrate. The film layer prevents reflow of the standoff bump at the eutectic temperature. A second bump is disposed between a semiconductor die and the first bump. The second bump is reflowed to electrically connect the semiconductor die to the first bump. After reflow of the second bump, the standoff bump has a height at least 70% of the second bump prior to reflow to maintain separation between the semiconductor die and substrate. | 01-28-2010 |

20140015811 | INPUT METHOD AND ELECTRONIC DEVICE USING PEN INPUT DEVICE - An input method and electronic device using a pen input device are provided. In an embodiment, status information of the pen input device is received, and contact information of a contact point between the pen input device and the terminal is generated, based on the received status information. Expressive effects of a pen input, such as line thickness, density and texture, are varied based on the contact information. Such input method and electronic device using the pen input device can simply and conveniently vary expressive effects of a pen-based input. In other embodiments, contact information is determined from actual contact points and expressive effects are varied as a function of the contact information or pen status information derived from the actual contact information. | 01-16-2014 |
20140049652 | CAMERA DEVICE AND METHODS FOR AIDING USERS IN USE THEREOF - Provided are a method of controlling photographing in a camera device such as a portable terminal, which automatically sets a photographing mode using at least one of location information of the device and subject information, and a camera device thereof. A camera captures an image during a photographing mode of the device. A controller acquires meta data corresponding to the image based on at least one of the location information and subject information included in the image. A camera setting value is determined based on the acquired meta data, and the camera is automatically set according to the determined camera setting value. | 02-20-2014 |
