A major difference between 304 and 316 stainless steel is the chemical composition, with 316 containing a significant amount of molybdenum; typically 2 to 3 percent by weight vs only trace amounts found in 304.

Light Emission from Rare-Earth Doped Silicon …

2007-12-5 · Rare earth (Tb or Ce)-doped silicon oxides were deposited by electron cyclotron resonance plasma-enhanced chemical vapour deposition (ECR-PECVD). Silicon nanocrystals (Si-ncs) were formed in the silicon-rich films during certain annealing processes. Photoluminescence (PL) properties of the films were found to be highly dependent on the deposition parameters and annealing conditions.

On-wafer S-parameter de-eedding of silicon active …

It is demonstrated using transformers, capacitors, 65 nm MOSFETs and SiGe HBTs that, if the open and short dummies are designed to remain lumped through 170 GHz, there is almost no difference between the three de-eedding techniques. For transistor test structures with series ground inductance, a new TRL + short de-eedding method is proposed.
