Abstract:
A molding core includes: a core body having an article-shaping surface; an intermediate film formed on the article-shaping surface of the core body and including a first composite layer that contains carbon, nitrogen, and at least one bonding-enhancing element which is selected from silicon, titanium, aluminum, tungsten, tantalum, chromium, zirconium, vanadium, niobium, hafnium, and boron, and which forms covalence bonding with the carbon and the nitrogen; and a hard coating that includes a carbon film formed on the intermediate film.
Abstract:
A method of fabricating a copper capping layer. A silicon rich nitride layer is formed on an exposed copper layer. Since the silicon rich nitride layer has more dangling bonds inside, the silicon in the silicon rich nitride layer easily reacts with the copper and a copper silicide layer is formed between the copper and the silicon rich nitride layer. Therefore, adhesion of the copper and the silicon rich nitride layer can be improved.
Abstract:
A pre-process before cutting a wafer is described. The wafer includes a plurality of scribe lines and a plurality of dies defined by the scribe lines, and a material layer covers the wafer. A pre-processing step is performed to remove the material layer on the scribe lines close to the corner regions of the dies. Removing the material layer at the corner regions before cutting the wafer is able to preserve the integrity of the corner regions of the cut dies.
Abstract:
An optical article includes a glass sheet having a top surface, a bottom surface, an array of optical elements formed between the top and bottom surfaces and arranged in rows that intersect each other along two intersecting cutting directions of the glass sheet, and at least two aligning marks formed on one of the top and bottom surfaces and spaced apart from each other in one of the cutting directions. A molding assembly for making the optical article is also disclosed.
Abstract:
The present invention relates to a method for manufacturing a wafer level chip scale package structure including the following steps. After providing a glass substrate and a wafer comprising a plurality of chips, the active surface of the wafer is connected to the top surface of the glass substrate. The wafer is connected with the glass substrate through either bumps or pads thereon. After drilling the glass substrate to form a plurality of through holes, a plating process is performed to form a plurality of via plugs in the through holes. Afterwards, a singulation step is performed and a plurality of chip scale package structures is obtained.
