Abstract: A method for forming semiconductor devices includes providing a substrate with a conductive pad formed thereon; forming a transparent structure over the substrate, wherein the transparent structure includes a plurality of collimating pillars adjacent to the conductive pad; forming a light-shielding structure over the plurality of collimating pillars and the conductive pad; performing a cutting process to remove one or more materials directly above the conductive pad, while leaving remaining material to cover the conductive pad, wherein the material includes a portion of the light-shielding structure; and performing an etching process to remove the remaining material to expose the conductive pad.

Abstract: The invention relates to a container structure with a dispensing valve capable of completely draining tea or drink contained therein without the tea or drink being wasted. The container structure is made of a metal material, which is circled to form a cylindrical sidewall. A baseplate is tightly joined to a bottom end of the sidewall. The baseplate crosses two opposite sides of the sidewall and gradually tilts. The dispensing valve corresponding to a lowest portion of the container structure and the inclined baseplate is mounted to the sidewall. When the container structure is placed horizontally or slantingly, the liquid contained in the container structure can fully flow to the dispensing valve and be drained out.
