摘要:
A method of selectively forming contact regions on a substrate having a plurality of exposed regions includes selectively forming a contact region on each of the exposed regions of the substrate. During formation, each contact region has a first growth rate in a first direction and a second growth rate in a second direction. While each contact region is being selectively formed on the respective exposed region, the contact region is heated to increase the first growth rate of the contact region in the first direction relative to the second growth rate of the contact region in the second direction. The first growth rate may be a vertical growth rate and the second growth rate may be a lateral growth rate. The contact may be heated by applying electromagnetic radiation to an upper surface of the substrate and not applying the radiation to the vertical portions of the contact region to thereby increase the vertical growth rate relative to the lateral growth rate. The electromagnetic radiation may be collimated light such as that generated by a scanning laser beam, and the substrate and formed contact regions may be silicon or other suitable materials. This method may be used during the fabrication of MOS transistors in memory devices and other integrated circuits.

An oral appliance for administering a stimulus, such as a substance, to the mouth of a user includes a flexible tube having an inlet portion, a first curved portion forming an ear loop connected to the inlet portion, a second curved portion forming a lip bend connected to the first curved portion, and an outlet portion extending from the second curved portion. Alternatively, a mouthpiece for delivering a substance to the mouth of a user includes a housing having an inlet portion, a riser portion extending upwardly from the inlet portion and a curved outlet portion. A flexible tube is coupled to the housing. A method of delivering a substance to a predetermined location in a user's mouth includes disposing a flexible tube between a row of teeth and an interior surface of a cheek. The flexible tube has an exit port positioned in a rear portion of the user's mouth. No portion of the flexible tube is disposed between the upper and lower teeth of the user such that the upper and lower teeth can be closed against each other. The method further includes dispensing a substance through the exit port.

An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 μm.

A track set is disclosed herein, the track set having: a first track segment pivotally mounted to the track set for movement between a first position and a second position, the first track segment having a first end and a second end; a perforated vessel secured to the first end of the first track segment, wherein a predetermined amount of water in the perforated vessel will maintain the first track segment in the first position; a second track segment mounted to the track set, the second end of the first track segment being spaced from a receiving end of the second track segment and the second end of the first track segment being elevated from the receiving end of the second track segment when the first track segment is in the first position, wherein at least one toy vehicle positioned proximate to the first end of the first track segment will be held there until an amount of water in the perforated vessel is less than the predetermined amount and the first track segment moves from the first position to the second position, wherein the least one toy vehicle travels away from the first end of the first track segment to the second track segment by traversing a gap between the second end of the first track segment and the receiving end of the second track segment.
摘要:
Structures and methods for making a semiconductor structure are discussed. The semiconductor structure includes a rough surface having protrusions formed from an undoped silicon film. If the semiconductor structure is a capacitor, the protrusions help to increase the capacitance of the capacitor. The semiconductor structure also includes a relatively smooth surface abutting the rough surface, wherein the relatively smooth surface is formed from a polycrystalline material.
