摘要： A method of forming a fin field effect transistor on a semiconductor substrate includes forming a fin-shaped active region vertically protruding from the substrate. An oxide layer is formed on a top surface and opposing sidewalls of the fin-shaped active region. An oxidation barrier layer is formed on the opposing sidewalls of the fin-shaped active region and is planarized to a height no greater than about a height of the oxide layer to form a fin structure. The fin structure is oxidized to form a capping oxide layer on the top surface of the fin-shaped active region and to form at least one curved sidewall portion proximate the top surface of the fin-shaped active region. The oxidation barrier layer has a height sufficient to reduce oxidation on the sidewalls of the fin-shaped active region about halfway between the top surface and a base of the fin-shaped active region. Related devices are also discussed.

摘要： Polysaccharides, which are widely used as an anticoagulation drugs, especially heparin, are clinically administered only by intravenous or subcutaneous injection because of their strong hydrophilicity and high negative charge. Amphiphilic heparin derivatives were synthesized by conjugation to bile acids, sterols, and alkanoic acids, respectively. These heparin derivatives were slightly hydrophobic, exhibited good solubility in water, and have high anticoagulation activity. These slightly hydrophobic heparin derivatives are efficiently absorbed in the gastrointestinal tract and can be used in oral dosage forms. Methods of using these amphiphilic heparin derivatives and similarly modified macromolecules for oral administration are also disclosed.
