Abstract: A photo resist layer is used to protect a dielectric layer and conductive elements embedded in the dielectric layer when patterning an etch stop layer underlying the dielectric layer. The photo resist layer may further be used to etch another dielectric layer underlying the etch stop layer, where etching the next dielectric layer exposes a contact, such as a gate contact. The bottom layer can be used to protect the conductive elements embedded in the dielectric layer from a wet etchant used to etch the etch stop layer.

Abstract: An integrated hardcover production method and device comprising: a moving belt 1 installed inside a frame 10 horizontally moves a plurality of sheets 5 from a first end to a second end thereof; a stop plate 2 installed to a second end of the moving belt 1 aligns a spine 51 of the plurality of sheets 5; a set of forming rollers 22 installed along a first side of the stop plate 2 gradually convex inward; a translating device 3 moves transversely on the stop plate 2 inside the frame 10 to and fro, thereby the plurality of sheets 5 gripped by the translating device 3, the spine 51 flattened by passing through the forming rollers 22.

Abstract: An automatic card cutter capable of continuously cutting paper material of various amounts and sizes comprises a feeding unit, a transport unit, a transverse cutting unit, a longitudinal cutting unit, a waste material collector, a card collector and a shell body. The feeding unit has two spacing-adjustable side plates. Each of the side plates is provided with a flexible plate, an impression wheel against the flexible plate and drive set for driving the impression wheel, whereby paper materials of various amounts can be fed into the cutter smoothly. The longitudinal cutting unit comprises a plurality of slidable wheel knife sets, so that the cutting width of the paper material can be easily set.
