Abstract: The process flow in the fabrication of MOSFETs having a LDD is altered by using a combination of arsenic and phosphorus to tailor the lateral profile to meet both series resistance and channel hot carrier requirements. In this process flow, the relatively higher dose arsenic controls the series resistance and the lighter phosphorus dose sets the lateral junction profile. Therefore, a profile intermediate the arsenic only and the phosphorus only can be achieved. In forming a LDD in accordance with the present invention, the arsenic implant dose is relatively high. The lateral extend of the LDD is varied to meet the hot carrier lifetime by varying the lighter phosphorus implant dose. This procedure is achieved using standard process technology.

Abstract: Many integrated circuits include a type of transistor known as a bipolar junction transistor, which has an emitter contact formed of polysilicon. Unfortunately, polysilicon has a relatively high electrical resistance that poses an obstacle to improving switching speed and current gain of bipolar transistors. Current fabrication techniques involve high temperature procedures that melt desirable low-resistance substitutes, such as aluminum, during fabrication. Accordingly, one embodiment of the invention provides an emitter contact structure that includes a polysilicon-carbide layer and a low-resistance aluminum, gold, or silver member to reduce emitter resistance. Moreover, to overcome manufacturing difficulties, the inventors employ a metal-substitution technique, which entails formation of a polysilicon emitter, and then substitution of metal for the polysilicon.

In another preferred implementation, such conductive lines form a grid of insulating material which, in turn, defines the node location. According to a preferred aspect of the invention, a plurality of insulated conductive lines are formed over a substrate.

Abstract: An oxide etching method, particularly applicable to forming through an oxide layer a wineglass shaped contact or via hole of controlled shape. The wineglass hole is particularly useful for eased metal hole filling. The bowl is etched by first etching an anisotropic hole through a mask aperture, and then isotropically etching through the same mask aperture. The relative periods of the anisotropic and isotropic etch determine the lateral-to-vertical dimensions of the bowl. The stem is then etched through the same mask aperture with a strongly anisotropic etch. The isotropic etch may be performed in the same chamber as the anisotropic etch or may advantageously be performed in a separate etch chamber having a remote plasma source.

Abstract: A ridge vent assembly extends along the ridge of the roof of a building structure and is provided with multiple plies of corrugated material. The corrugations of the plies define small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A flexible member consisting of a strip of cloth material extends along the outer edge of the vent parts. The strip of material terminates into a flexible bubble. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the cloth strip and bubble act as a weatherstripping material for the vent.
