A process for spin-on coating with an organic material having a low dielectric constant, which is suitable for a substrate. A dielectric base layer capable of protecting metal is formed on the substrate, an adhesive promoter layer is formed on the dielectric base layer, and the adhesive promoter layer is baked. A solvent is then used to clean the substrate and simultaneously to dissolve a part of the adhesive promoter layer in order to flatten the adhesive promoter layer. Afterwards, a layer of an organic material with a low dielectric constant is spin-on coated on the adhesive promoter layer, and the layer of an organic material with a low dielectric constant is baked and cured.

A method for forming dual damascene is provided. First, a first inter-metal dielectric layer and a stop layer is formed on a substrate, and then a first photoresist pattern including a via hole and a dummy metal line is patterned and the stop layer is etched for forming via hole. Next, a second inter-metal dielectric layer is deposited and then a second photoresist pattern is patterned for forming metal line trench by etching. Afterwards, a glue layer and a metal layer are blanketed and the dual damascene structure is formed by chemical mechanical polishing.

A liner for a cargo container includes an expansible liner body shaped to fit a cargo space of the cargo container. The liner body includes top and bottom panels, left and right panels interconnecting the top and bottom panels, and front and rear panels. The top, bottom, left, right, front and rear panels together define an accommodation space thereamong for receiving bulk cargo. The rear panel has an outlet opening communicated with the accommodation space. Two first and second reinforcing members are secured respectively to and along the front edges of the left and right panels. Two first and second connecting members are secured respectively to and along the left and right edges of the bottom panel near the rear panel. Two left and right pulling members are mounted respectively to the first and second connecting members to pull the first and second connecting members upwardly and to raise the dead corners formed adjacent to the first and second connecting members to cause parts of the bulk cargo retaining in the dead corners to fall towards the outlet opening.
