20120253729 | Test system, test signal auxiliary device, and test signal generation method thereof - A test system, a test signal auxiliary device, and a test signal generation method thereof are disclosed. The test signal auxiliary device is used for providing a computer system to test a signal measurement device. The test signal auxiliary device includes a first signal input terminal used for receiving an analog test signal via a first audio port of the computer system. A filter module is used for filtering the analog test signal to produce a filtered signal. A first signal output terminal is used for outputting the filtered signal to the signal measurement device. A second signal input terminal is used for receiving a corresponding signal from the signal measurement device. A second signal output terminal is used for transmitting the corresponding signal to the computer system via a second audio port. | 10-04-2012 |

20130307520 | MICROELECTRODE ARRAY AND METHOD FOR MODIFYING CARBON NANOTUBE ELECTRODE INTERFACE OF THE SAME ARRAY - The present invention discloses a method for modifying a carbon nanotube electrode interface, which modifies carbon nanotubes used as a neuron-electrode interface by performing three stages of modifications and comprises the steps of: carboxylating carbon nanotubes to provide carboxyl functional groups and improve the hydrophilicity of the carbon nanotubes; acyl-chlorinating the carboxylated carbon nanotubes to replace the hydroxyl functional groups of the carboxyl functional groups with chlorine atoms; and aminating the acyl-chlorinated carbon nanotubes to replace the chlorine atoms with a derivative having amine functional groups at the terminal thereof. The modified carbon nanotubes used as the neuron-electrode interface has lower impedance and higher adherence to nerve cells. Thus is improved the quality of neural signal measurement. The present invention also discloses a microelectrode array, wherein the neuron-electrode interface uses carbon nanotubes modified according to the method of the present invention. | 11-21-2013 |

20160133746 | High Mobility Devices and Methods of Forming Same - An embodiment method includes forming a first fin and a second fin over a semiconductor substrate. The first fin includes a first semiconductor strip of a first type, and the second fin includes a second semiconductor strip of the first type. The method further includes replacing the second semiconductor strip with a third semiconductor strip of a second type different than the first type. Replacing the second semiconductor strip includes masking the first fin using a barrier layer while replacing the second semiconductor strip and performing a chemical mechanical polish (CMP) on the third semiconductor strip using a slurry that planarizes the third semiconductor strip at a faster rate than the barrier layer. In some embodiments, the method may further include depositing a sacrificial layer over a wafer containing the first and second fins and performing a non-selective CMP to substantially level a top surface of the wafer. | 05-12-2016 |
