According to an embodiment of the invention, a chip package is provided. The chip package includes a substrate having an upper surface and a lower surface, a plurality of conducting pads located in the substrate or under the lower surface thereof, a dielectric layer located between the conducting pads, a hole extending from the upper surface towards the lower surface of the substrate and exposing a portion of the conducting pads, and a conducting layer located in the hole and electrically contacting the conducting pads.
Abstract:
The present invention provides a mask comprising a substrate, a plurality of strip patterns and at least an assist pattern. The strip patterns are disposed on the substrate and arranged in parallel to one another. The assist pattern is in a strip shape and disposed on the substrate. The assist pattern is arranged in parallel to and outside of the outermost strip pattern of the strip patterns. The assist pattern and the strip pattern have the same phase, while the assist pattern has a width larger than that of the strip patterns. When the mask is applied for exposure process, the pattern of the assist pattern will not be transferred to the underlying layer to be exposed.
Abstract:
A rework process of patterned photo-resist layer is provided. First, a substrate is provided with a first DARC, a first primer and a first patterned photo-resist layer being sequentially formed thereon. Next, remove the first patterned photo-resist layer and the first primer from the first DARC. After that, form a second DARC on the first DARC; form a second primer on the second DARC. Last, form a second patterned photo-resist layer on the second primer.
Abstract:
A sandwich ARC structure for preventing metal to contact from shifting, the sandwich ARC structure comprising a first Ti layer formed on a metal laer and a first TiN layer formed on the first Ti layer. A second Ti layer is formed on the first TiN layer and a second TiN layer is formed on the second Ti layer. Wherein the sandwich ARC structure formed of first Ti/first TiN/second Ti/second TiN will reduces the tress between said metal layer and a dielectric layer formed below the metal layer.
Abstract:
An integrated circuit capable of operating despite a profile shift is disclosed. Overlay marks on the integrated circuit are surrounded by a trench that tends to relieve the effect of a profile shift caused by stress applied to the integrated circuit. The position of the overlay marks tends, therefore, not to be affected by the stress.
