Mechanical Characterization of the Heat Affected Zone of Gold Wirebonds Using Nanoindentation
(2002-01)With increasing miniaturization in microelectronics the wirebonds used in IC packages are witnessing a thrust towards fine pitch wirebonding. To have a precise control over loop height of the wirebond for fine pitch ... -
A Mechanical Model for Erosion in Copper Chemical-Mechanical Polishing
(2003-01)The Chemical-mechanical polishing (CMP) process is now widely employed in the ultralarge scale integration chip fabrication. Due to the continuous advances in semiconductor fabrication technology and decreasing sub-micron ... -
Mechanical Properties of Bulk Metallic Glasses and Composites
(2004-01)We have studied the mechanical properties of monolithic bulk metallic glasses and composite in the La based alloys. La₈₆₋yAl₁₄(Cu, Ni)y (y=24 to 32) alloy systems was used to cast the ... -
Mechanical properties of La-based bulk amorphous alloy and composites
(2003-01)Influence of different microstructure of La-based fully amorphous samples and its composites on the impact fracture energy were investigated and discussed. Results showed improvement in fracture energy of glassy metals ... -
Mechanics,Mechanisms and Modeling of the Chemical Mechanical Polishing Process
(2002-01)The Chemical Mechanical polishing (CMP) process is now widely employed in the Integrated Circuit Fabrication. However, due to the complexity of process parameters on the material removal rate (MRR), mechanism of material ... -
A Media Player for Use in Distance Education
(2004-01)We have developed a media player for use in distance education. The player can incorporate several time-indexed sources, including video, audio, PowerPoint, and text index. We have converted all the SMA 5503 Introduction ... -
Memory Hierarchy Hardware-Software Co-design in Embedded Systems
(2005-01)The memory hierarchy is the main bottleneck in modern computer systems as the gap between the speed of the processor and the memory continues to grow larger. The situation in embedded systems is even worse. The memory ... -
Memory Usage Inference for Object-Oriented Programs
(2005-01)We present a type-based approach to statically derive symbolic closed-form formulae that characterize the bounds of heap memory usages of programs written in object-oriented languages. Given a program with size and alias ... -
MEMS Materials and Processes: a research overview
(2003-01)An overview is provided of materials and processes research currently being conducted in support of MEMS device design at MIT. Underpinning research is being conducted in five areas: room temperature strength characterization, ... -
A Meshfree Weak- Strong-form (MWS) method for solid and fluid mechanics
(2004-01)Mesh free methods can be largely categorized into two main categories: mesh free methods based on strong forms (e.g. collocation methods) and mesh free methods based on the weak forms (EFG, MLPG, PIM, etc.; see Mesh Free ... -
Metallic Cluster Coalescence: Molecular Dynamics Simulations of Boundary Formation
(2003-01)During the evaporative deposition of polycrystalline thin films, the development of a tensile stress at small film thicknesses is associated with island coalescence. Several continuum models exist to describe the magnitude ... -
Metastable Intermediate in LixMnO₂ Layered to Spinel Phase Transition
(2002-01)Ab Initio calculations suggest that partially lithiated layered LixMnO₂ transforms to spinel in a two-stage process. In the first stage, a significant fraction of the Mn and Li ions rapidly occupy tetrahedral sites, forming ... -
Methods for Calculating the Optical Band Structure of Photonic Composites
(2002-01)Lately, there has been an increasing interest in studying the propagation of electromagnetic waves in periodic dielectric structures (photonic crystals). Like the electron propagation in semiconductors, these structures ... -
Micro Injection-Molding of Cyclic Olefin Copolymer Using Metallic Glass Insert
(2007-01)There is shift in trend towards the use of high quality polymers as the base material in manufacturing microfluidic chips. In this paper, an amorphous metallic alloy mold insert was used in a micro injection-molding process ... -
Micro Raman Spectroscopy of Annealed Erbium Implanted GaN
(2004-01)Wurtzite GaN epilayers grown by metal organic chemical vapor deposition on sapphire substrates were subsequently ion implanted with Er to a dose of 5×10¹⁵ cm⁻². The implanted samples were annealed in nitrogen atmosphere ... -
Micro-layered-photolithography for Micro-Fabrication and Micro-Molding
(2005-01)A novel process based on the principle of layered photolithography has been proposed and tested for making real three-dimensional micro-structures. An experimental setup was designed and built for doing experiments on this ... -
Micro-porous Paclitaxel-Loaded PLGA Foams -- a New Implant Material for Controlled Release of Chemotherapeutic Agents
(2007-01)Supercritical gas foaming using CO₂ was used to fabricate blank poly DL lactide-co-glycolide (PLGA) micro-porous foams. Paclitaxel-loaded PLGA foams were also produced for the first time using a modification of the ... -
MicroRNAs Modulate Hematopoietic Lineage Differentiation
(2005-01)MicroRNAs (miRNAs), an abundant class of ~22 nucleotide non-coding RNAs, are thought to play an important regulatory role in animal and plant development at the posttranscriptional level. Many miRNAs cloned from mouse bone ... -
Mining Of Text In The Product Development Process
(2002-01)In the prevailing world economy, competition is keen and firms need to have an edge over their competitors for profitability and sometimes, even for the survival of the business itself. One way to help achieve this is the ... -
