Congenital disorders of glycosylation (CDG) arise from pathogenic mutations in over 100 genes leading to impaired protein or lipid glycosylation. ALG1 encodes a β1,4 mannosyltransferase that catalyzes the addition of the first of nine mannose moieties to form a dolichol‐lipid linked oligosaccharide intermediate required for proper N‐linked glycosylation. ALG1 mutations cause a rare autosomal recessive...
Thermal compression bonding is being widely used for fine pitch copper pillar assembly as it provides high die placement accuracy and bonding suitable for mass production. In the current work, chip package interaction induced ILD integrity failures under thermo-compression assembly induced stresses were investigated. A step by step EFA (Electrical Failure Analysis) plus PFA (Physical Failure Analysis)...
Methods for growing periodically alternating polarities of GaN on GaN substrates have been developed. The resulting periodically oriented samples can be extended to thick growth, allowing their use in non-linear optics.
There has been a growing need for fine pitch flip chip technology in support of next generation communication devices with increasing die complexities. The increase in functionality which drives a larger number of signal I/O's in combination with small die size requirements as a result of transistor size reductions have driven the need to investigate finer die interconnect pitches. Traditional solder...
A room temperature 4.5µm laser is reported in Er: KPb2Cl5 crystals using 0.8µm diode excitation. Long fluorescent lifetimes lead to important ETU and ESA processes. The impact of these excitation channels on laser performance is assessed.
High-quality single crystals of Er3+:KPb3Cl 5 have been grown by a novel modification of the Bridgman method. These crystals show excellent laser performance at 4.6 mum
