A motorized wheeled chair assembly facilitates movement by a person while seated on a chair. The assembly includes a frame and a plurality of wheels coupled to the frame. A seat and a motor are coupled to the frame. The motor is operationally coupled to one of the wheels defining a motorized wheel wherein the motor rotates the motorized wheel. A handle is coupled to the frame by an arm having a first end coupled to the handle and a second end removably coupled to the frame. A motor control is coupled to the handle and operationally coupled to the motor.

A via contact is provided to a diffusion region at a top surface of a substrate which includes a single-crystal semiconductor region. The via contact includes a first layer which consists essentially of a silicide of a first metal in contact with the diffusion region at the top surface. A dielectric region overlies the first layer, the dielectric region having an outer surface and an opening extending from the outer surface to the top surface of the substrate. A second layer lines the opening and contacts the top surface of the substrate in the opening, the second layer including a second metal which lines a sidewall of the opening and a silicide of the second metal which is self-aligned to the top surface of the substrate in the opening. A diffusion barrier layer overlies the second layer within the opening. A third layer including a third metal overlies the diffusion barrier layer and fills the opening.

A communication system ( ) uses commercial, mass market paging transmission facilities ( ) to deliver messages ( &prime;) to a population of reception devices ( ). Each reception device ( ) includes a display screen ( ) at which lines ( ) of national and local news and advertising, a banner advertising box ( ) and a clock ( ) are displayed. Line buttons ( &prime;) are aligned with the displayed lines ( ). The reception device ( ) is configured so that a user may press a line button ( &prime;) aligned with a particular line ( ) scrolling on the display screen ( ) to view additional details related to the subject matter of the particular line ( ). Selected lines ( ) include alert activating codes ( ) which signal the reception device ( ), when enabled, to activate an alert which attracts the user's attention to those selected lines ( ).

A method for forming a TiN layer on top of a metal silicide layer in a semiconductor structure without the formation of a thick amorphous layer containing Ti, Co and Si and the structure formed are provided. In the method, after a Ti layer is deposited on top of a metal silidide layer, a dual-step annealing process is conducted in which a low temperature annealing in a forming gas (or ammonia) at a temperature not higher than 500&deg; C. is first conducted for less than 2 hours followed by a high temperature annealing in a nitrogen-containing gas (or ammonia) at a second temperature not lower than 500&deg; for less than 2 hours to form the TiN layer. The present invention method prevents the problem usually caused by a thick amorphous material layer of Ti&mdash;Si&mdash;Co which produces weakly bonded Ti which reacts with fluorine atoms from WF during a subsequent CVD W deposition process and causes liner failure due to a volume expansion of the amorphous material. The maximum thickness of the amorphous material layer formed by the present invention method is less than 5 nm which minimizes the line failure problem.

A method of forming an integrated barrier/contact for stacked capacitors is provided which results in reduced cost of ownership and in a barrier which is nominally several times thicker than convention structures. The resulting structure results in decreased contact plug resistance as compared with conventional devices.

An improved telephone with three built in features that provide added conveniences and additional benefits for the user. These features are: Money Saver Timer, which tells the caller the amount of time is left of the current message or toll unit on a long distance call; Telephone Panic Switch, when pressed, will activate a circuit to automatically call and broadcast an emergency message to a group of pre-stored numbers; Music On Hold cards, which allow the user to play different music programs for the HOLD feature. These cards can be changed frequently to provide different music programs to the frequent caller.
