| 20090079414 | USING FLOATING GATE FIELD EFFECT TRANSISTORS FOR CHEMICAL AND/OR BIOLOGICAL SENSING - Specific ionic interactions with a sensing material that is electrically coupled with the floating gate of a floating gate-based ion sensitive field effect transistor (FGISFET) may be used to sense a target material. For example, an FGISFET can use (e.g., previously demonstrated) ionic interaction-based sensing techniques with the floating gate of floating gate field effect transistors. The floating gate can serves as a probe and an interface to convert chemical and/or biological signals to electrical signals, which can be measured by monitoring the change in the device's threshold voltage, V | 03-26-2009 |

| 20120139102 | DISPOSING UNDERFILL IN AN INTEGRATED CIRCUIT STRUCTURE - In one embodiment, a method of forming a multi-die semiconductor device is provided. A plurality of dice is mounted on a semiconductor substrate, and neighboring ones of the dice are separated by a distance at which a first one of the neighboring dice will contact a meniscus of a flange of the neighboring die during underfill to form a capillary bridge between the neighboring dice. Solder bumps are reflowed to electrically connect contact terminals of the plurality of dice to contact terminals on a top surface of the substrate. Underfill is deposited along one or more edges of one or more of the plurality of dice. As a result of the capillary bridge formed between neighboring dice, flow of underfill is induced between the bottom surfaces of the neighboring dice and the top surface of the substrate. The dispensed underfill is cured. | 06-07-2012 |
