摘要:
A method for forming, within a low dielectric constant dielectric layer formed upon a substrate employed within a microelectronics fabrication, a conductor pattern employing a hard mask cap layer. There is first provided a substrate having conductor regions formed therein upon which is formed a low dielectric constant dielectric layer. There is then formed over the substrate a silicon containing hard mask cap layer. There is then formed over the hard mask cap layer a patterned photoresist etch mask layer. There is then subtractively etched employing the patterned photoresist etch mask layer and a first subtractive etching environment the pattern into the hard mask layer. There is then subtractively etched employing the patterned hard mask layer and a second etching environment the pattern into the low dielectric constant dielectric layer, simultaneously stripping the photoresist etch mask layer. There is then removed by delamination the hard mask cap layer employing a chemical treatment, leaving a trench pattern in the low dielectric constant dielectric layer. The trench pattern may be filled with a microelectronics material to form a patterned layer around which is a maximized amount of low dielectric constant dielectric material. The order of filling with microelectronics material and delamination of the hard mask layer may be reversed if desired to minimize the amount of patterned microelectronics material remaining above the substrate surface, in which case the method is a lift off method for patterning a microelectronics layer. After filling and patterning, the substrate surface may be planarized for further processing and optional additional microelectronics layers formed thereover.

This invention relates to a method of fabrication used for semiconductor integrated circuit devices, and more specifically to the use an alternate etch stop in dual damascene interconnects that improves adhesion between low dielectric constant organic materials. In addition, the etch stop material is a silicon containing material and is transformed into a low dielectric constant material (k=3.5 to 5), which becomes silicon-rich silicon oxide after UV radiation and silylation, oxygen plasma.

A method for forming a planarized interlevel dielectric layer without degradation due to the microloading effect from spin-on material etchback is described. A patterned first conducting layer is provided over an insulating layer on a semiconductor substrate. An improved interlevel dielectric layer is formed overlying the patterned first conducting layer by the following steps. A first oxide layer is deposited overlying the patterned first conducting layer and the insulating layer. A spin-on material layer is coated overlying the first oxide layer and etched back using O.sub.2 gas added to the CHF.sub.3 /CF.sub.4 chemistry until the first oxide layer is exposed overlying the patterned first conducting layer wherein microloading effects from the etching back of the spin-on material layer are lower than microloading effects in a conventional interlevel dielectric layer. A second oxide layer is deposited to complete the interlevel dielectric layer. A second conducting layer is deposited over the interlevel dielectric layer and patterned to complete the fabrication of the integrated circuit device.

A new heat dissipation structure for sealed optical machines comprises an optical machine housing, an LED light source, a light cone, a first Fresnel lens, heat insulating glass, a liquid crystal screen, a second Fresnel lens, and a reflector; the upper part of the optical machine housing is installed with a second heat dissipation fan. The invention adopts two independent heat dissipation systems inside and outside, which can greatly increase the heat dissipation performance of the optical machine, and the external heat sink of the external heat dissipation system and the light heat sink share a fan in parallel, simplifying the structure and reducing the cost. The second heat dissipation fan is integrated with the optical machine shell, which effectively reduces the height of the optical machine, reduces the volume of the optical machine, and achieves a better internal circulation, further improving the heat dissipation efficiency.

Clustering a plurality of client devices running an application as a function of a data structure such that the plurality of client devices are each assigned a cluster. Client devices having similar performance metrics are assigned the same cluster. An operation of the application is modified as a function of the performance metrics of the client device. The modification of application operation is performed by turning certain features of the application on and off using a rule based on device cluster.

The present invention relates to solar lighting device, in particular, an illuminating solar display panel comprising display of a transparent illustration on the solar panel. The present invention has dual functional abilities of collecting solar power as a power supply unit and present illuminating illustration as a display unit, whereby an illustration is cutout from the dark coloured material layers of the power supply panel creating a transparent illustration; thereby, light can enter from behind the panel and create an illuminating effect to the illustration. Instead of two separate components, compromise of solar panel(s) and illuminating display unit, the current invention combines two separate units into one independent power efficient illuminating solar display apparatus.

A backlight module (30) includes a light guide plate and a light source (210). The light guide plate includes a light incident surface, and a light diffusion cavity (308) disposed corresponding to the light incident surface. The light source is disposed adjacent to the light incident surface. One of surfaces (309) of the light guide plate defining the light diffusion cavity includes a plurality of prism structures, the surface being the one nearest to the light incident surface. Most of the light from the light source can be diffused uniformly by the prism structures before entering an efficient display area of the light guide plate. This reduces or eliminates what would otherwise be one or more dark areas in the light guide plate, and results in the uniform emitting of light from the light guide plate.
