Methods of minimizing or eliminating plasma damage to low k and ultra low k organosilicate intermetal dielectric layers are provided. The reduction of the plasma damage is effected by interrupting the etch and strip process flow at a suitable point to add an inventive treatment which protects the intermetal dielectric layer from plasma damage during the plasma strip process. Reduction or elimination of a plasma damaged region in this manner also enables reduction of the line bias between a line pattern in a photoresist and a metal line formed therefrom, and changes in the line width of the line trench due to a wet clean after the reactive ion etch employed for formation of the line trench and a via cavity. The reduced line bias has a beneficial effect on electrical yields of a metal interconnect structure.

A dense boron-based or phosphorus-based dielectric material is provided. Specifically, the present invention provides a dense boron-based dielectric material comprised of boron and at least one of carbon, nitrogen, and hydrogen or a dense phosphorus-based dielectric comprised of phosphorus and nitrogen. The present invention also provides electronic structures containing the dense boron-based or phosphorus-based dielectric as an etch stop, a dielectric Cu capping material, a CMP stop layer, and/or a reactive ion etching mask in a ULSI back-end-of-the-line (BEOL) interconnect structure. A method of forming the inventive boron-based or phosphorus-based dielectric as well as the electronic structure containing the same are also described in the present invention.
摘要:
Novel liquid crystal display (LCD) structures for full-color liquid crystal displays using photoluminescent (PL) fibers. The new architectures simplify the LCD fabrication process by replacing complicated, time consuming photolithography steps for color filter fabrication to a low-cost, high-throughput fiber spinning technology. The new LCD architecture implementing the approach has a higher power efficiency than conventional LCDs. Three structures of LCD devices utilizing photoluminescent (PL) fiber arrays includes: a first structure having PL fiber arrays situated behind the LC shutter (relative to viewers); a second structure having PL fiber arrays situated on top of the LC shutter; and a third structure where the PL fiber arrays are located outside the LC cell. In one of these structures, the fibers not only photoluminesce, but also polarize incident light thus reducing LCD fabrication cost.
摘要:
Headgear apparatus allows a viewer to see objects in a periscopic direction and a normal direction simultaneously. A periscope is mounted to a headpiece that is easily supported by the viewers head. The periscope has movable mirrors and an extending periscope section to allow the viewer to change the angle of the periscopic view relative to a plane containing a normal line of sight and the peripheral distance of the periscopic view, respectively. The apparatus further has a sectional periscope, whereby sections containing the reflective elements of the periscope can be rotated relative to each other and change the periscopic view in the plane of the forward line of sight. The head gear apparatus is adapted to a mask or an underwater mask that allows a viewer to see objects in a periscopic direction and a forward direction in diverse environments such as under water.
