The Effects of Si Submounts Containing Cu Thermal Vias on the Heat-Dissipation Characteristics of a High-Power Light-Emitting Diode Package
We investigated the effects of Si submounts containing Cu thermal vias on the heat-dissipation characteristics of a high-power light-emitting diode (LED) package. Simulations were used to determine the optimum...

Effect of Al pre-deposition on AlN buffer layer and GaN film grown on Si (111) substrate by MOCVD
In this study, we investigated the effect of Al pre-deposition time on GaN crystal quality. The GaN layer was grown on a Si (111) substrate by metal organic chemical vapor deposition using an AlN buffer layer....

The effects of ambient oxygen pressure on the 1.54 μm photoluminescence of Er-doped silicon-rich silicon oxide films grown by laser ablation of a Si+Er target
We fabricated Er-doped silicon-rich silicon oxide (SRSO:Er) films by pulsed laser deposition. A Si+Er target consisting of an Er metallic strip and a silicon disk was adopted with a goal to achieve a convenien...

Investigation of interfacial reaction between Sn-Ag eutectic solder and Au/Ni/Cu/Ti thin film metallization
This paper reports the formation of intermetallic compounds in Au/Ni/Cu/Ti under-bump-metallization (UBM) structure reacted with Ag-Sn eutectic solder. In this study, UBM is prepared by evaporating Au(500 Å)/N...

Effect of BN Coating on the Strength of a Mullite Type Fiber
Nextel 480 is a polycrystalline essentially mullite fiber (70 wt.-% Al2O3+28 wt.-% SiO2+ 2 wt.-% B2O3). Different thicknesses of BN were applied as coatings on this fiber. Optical, scanning electron, and transmis...
