Method for etching organic low-k dielectric using ammonia, NH3, as an active etchant. Processes using ammonia results in at least double the etch rate of organic low-k dielectric materials than processes using N2 / H2 chemistries, at similar process conditions. The difference is due to the much lower ionization potential of NH3 versus N2 in the process chemistry, which results in significantly higher plasma densities and etchant concentrations at similar process conditions.

The invention is embodied in a method of processing a semiconductor workpiece in a plasma reactor chamber, including supplying a polymer and etchant precursor gas containing at least carbon and fluorine into the chamber at a first flow rate sufficient of itself to maintain a gas pressure in the chamber in a low pressure range below about 20 mT, supplying a relatively non-reactive gas into the chamber at second flow rate sufficient about one half or more of the total gas flow rate into the chamber, in combination with the first flow rate of the precursor gas, to maintain the gas pressure in the chamber in a high pressure range above 20 mT, and applying plasma source power into the chamber to form a high ion density plasma having an ion density in excess of 1010 ions per cubic centimeter. In one application of the invention, the workpiece includes an oxygen-containing overlayer to be etched by the process and a non-oxygen-containing underlayer to be protected from etching, the precursor gas dissociating in the plasma into fluorine-containing etchant species which etch the oxygen-containing layer and carbon-containing polymer species which accumulate on the non-oxygen-containing underlayer. Alternatively, the high pressure range may be defined as a pressure at which the skin depth of the inductive field exceeds {fraction (1 / 10)} of the gap between the inductive antenna and the workpiece.

Hibernating myocardium is characterized by viable myocardium with impaired function due to localized reduced perfusion. Hibernating myocytes retain cellular integrity, but cannot sustain high-energy requirements of contraction. High plasma levels of catecholamines, such as norepinepherine, are believed to be predictive of mortality from hibernating myocardium. Likewise, high levels of catecholamines lead to cardiomyopathy in patients with diabetes. GLP-1 reduces plasma norepinepherine levels, and it thus is useful in a method of treating hibernating myocardium or diabetic cardiomyopathy.

Nasal administration of the subject microemulsions produces a high plasma concentration of diazepam nearly as fast as intravenous administration. The present microemulsions are particularly suitable for a prompt and timely treatment of patients in the acute and / or emergency treatment of status epilepticus and other fever-induced seizures.
