  • Patent number: 7943422
    Abstract: Methods for producing a flip chip package by prepackaging one or more dice on a semiconductor wafer are provided. An embodiment of the method includes applying an adhesive to a first side of a finished wafer, where a number of dice are located. The active layer of the dice is on the first side of the finished wafer. The method further includes forming an array of conductive elements within the adhesive, where the array of conductive elements is electrically coupled to an array of connection pads on a die. The wafer can be diced to provide pre-packaged chips. To provide greater mounting densities, two or more dice may be coupled before application of the adhesive layer.

  • Patent number: 7939394
    Abstract: Multiple trench depths within an integrated circuit device are formed by first forming trenches in a substrate to a first depth, but of varying widths. Formation of a dielectric layer can cause some of the trenches to fill or close off while leaving other, wider trenches open. Removal of a portion of the dielectric material can then be tailored to expose a bottom of the open trenches while leaving remaining trenches filled. Removal of exposed portions of the underlying substrate can then be used to selectively deepen the open trenches, which can subsequently be filled. Such methods can be used to form trenches of varying depths without the need for subsequent masking.

  • Patent number: 7935625
    Abstract: A method of forming a metal line of a semiconductor memory device is disclosed. An interlayer insulating layer, an etch-stop layer, a trench oxide layer, a hard mask layer and a photoresist layer are laminated over a semiconductor substrate in which a contact is formed. An exposure process is performed to form a photoresist pattern. The hard mask layer is partially etched by an etch process that employs the photoresist pattern. An etch process using the hard mask layer as an etch mask is performed to partially etch the trench oxide layer, the etch-stop layer and the interlayer insulating layer, thereby forming damascene trenches. Metal material is formed on the entire surface including the trenches. A chemical mechanical polishing process is then performed to expose the etch-stop layer, thereby forming a metal line.
