They are: (1) requiring a time and labor intensive investigation to find a fault, (2) needing a significant change in a current material medium infrastructure to support a monitoring effort, or (3) reducing available bandwidth in a material medium due to a monitoring device intruding into the material medium to send data. These problems are solved, in accordance with a feature of the current invention, by monitoring a material medium with at least one diagnostic sensor, and using an electromagnetic (EM) signal, such as radio frequency (RF), signal to wirelessly transmit the sensor data.

20150349069 | FINFET SEMICONDUCTOR DEVICES WITH IMPROVED SOURCE/DRAIN RESISTANCE - A FinFET device includes a plurality of spaced-apart trenches in a semiconducting substrate, the plurality of spaced-apart trenches at least partially defining a fin for the FinFET device, wherein the fin comprises a first semiconductor material. A first layer of insulating material is positioned above a bottom surface of each of the plurality of spaced-apart trenches and an etch stop layer is positioned above an upper surface of the first layer of insulating material in each of the plurality of spaced-apart trenches. A metal silicide region is positioned on at least all sidewall surfaces of the fin that extend above the upper surface of the etch stop layer. | 12-03-2015 |
20160005867 | SILICIDE PROTECTION DURING CONTACT METALLIZATION AND RESULTING SEMICONDUCTOR STRUCTURES - A semiconductor transistor has a structure including a semiconductor substrate, a source region, a drain region and a channel region in between the source region and the drain region. A metal gate, having a top conductive portion of tungsten is provided above the channel region. A first silicon nitride protective layer over the source region and the drain region and a second silicon nitride protective layer over the gate region are provided. The first silicon nitride protective layer and the second silicon nitride protective layer are configured to allow punch-through of the first silicon nitride protective layer while preventing etching through the second silicon nitride protective layer. Source and drain silicide is protected by avoiding fully etching a gate opening unless either the etching used would not harm the silicide, or the silicide and source and drain contacts are created prior to fully etching an opening to the gate for a gate contact. | 01-07-2016 |
