Synthesis of Carbon Nanotubes (CNTs) as Thermal Interface Material
(2013-11-08)
Carbon nanotubes (CNTs) are promising materials for many potential applications. High
electrical conductivity, superior mechanical strength, thermal conductivity, and chemical
inertness are some of the properties of CNTs. ...
Test time optimization in scan circuits
(2010-11-10)
As circuit sizes increase with scale down in technology, the time required to test the circuits also increases. Expensive automatic test equipment (ATE) is used to test these circuits and the cost of testing becomes a ...
Testing and Diagnosis of CMOS Open Defects in the Presence of Common Hazards
(2015-07-29)
CMOS open defects are breaks in wires or defective transistors within some library cell causing pull up or pull down failure of the defective gates. Traditionally, TSOF (transistor stuck-open fault) is used to model such ...
Thick Film Packaging Techniques for 300°C Operation
(2011-08-11)
Geothermal well logging and instrumentation applications require electronics capable of 300°C operation. SiC device technology enables the design and fabrication of analog circuits that can operate at these temperatures. ...
Thin Film Multichip Packaging for High Temperature Geothermal Application
(2015-07-28)
A DOE sponsored study by MIT concluded that geothermal energy could provide 100,000 MWe or more in 50 years by using advanced technology knowns as Enhanced Geothermal Systems (EGS). In EGS, the measurement-while-drilling ...
Through Silicon Vias Using Liquid Metal Conductors For Reworkable Electronics
(2013-10-11)
The design and fabrication of liquid metal interconnects (vias) for reworkable 2.5D device
integration is presented in this work. We discuss the implementation of a fully reworkable
test module and a partially reworkable ...
True Three-Dimensional Proximity Effect Correction in Electron-beam Lithography: Control of Critical Dimension and Sidewall Shape
(2013-04-23)
One of the major limiting factors in electron-beam (e-beam) lithography is the geometric distortion of written features due to electron scattering, i.e., proximity effect, which puts a fundamental limit on the minimum ...
Typical Response of the ADXRS300 Microelectromechanical Systems (MEMS) Gyroscope in Acoustically Harsh Environments
(2009-08-03)
In this thesis, the basic theory behind vibratory MEMS gyroscopes will be discussed to show how some of the design parameters originate. Also, a survey of commercially available MEMS gyros will be presented. In addition, ...
UAV Collision Avoidance using A* Algorithm
(2012-04-13)
Collision avoidance is the essential requirement for unmanned aerial vehicles (UAVs) to become fully autonomous. Several algorithms have been proposed to do the path planning in a simulated environment, but only few can ...
