Abstract: A method of eliminating overhang in a contact hole formed in a contact film stack is described. A liner layer is overlaid on the contact film stack, the liner also coating the contact hole. A portion of the liner is removed to expose the overhang, and the exposed overhang is removed. The liner is also used to fill-in a bowing profile of the contact hole, thereby rendering sidewalls of the contact hole smooth and straight suitable for metal fill-in while suppressing piping defects.

Abstract: A cluster tool is disclosed that can increase throughput of a wafer fabrication process by facilitating removal of barrier overhang in contact holes of contact film stacks. Individual chambers of the cluster tool provide for deposition of barrier material onto a semiconductor structure, depositing over with an amorphous carbon film (ACF), etching back the ACF, and etching a corner region of the contact hole. Removal of the barrier overhang improves the quality of metal fill-in of the contact hole. An expectedly ensuing feature entails a technique in which filling-in of the contact hole with a metal such as tungsten can be achieved with attenuated or eliminated adverse consequence.

Abstract: A protective apparatus for a mobile device includes a protective layer unit, an inner support unit and a magnet unit. The protective layer unit includes an outer layer, an inner layer and a clamping strip. A mobile device is sandwiched between the clamping strip and the inner layer. The inner support unit includes a plurality of inner plates. The magnet unit includes a plurality of magnets. The protective layer unit further includes a plurality of recessed portions disposed between the inner plates. Thus, the protective layer unit is bendable at the recessed portions so that the protective layer unit is deformable freely.

Abstract: A method facilitates generally simultaneously fabricating a number of shallow trench isolation structures such that some selected ones of the shallow trench isolation structures have rounded corners and other selected ones of the shallow trench isolation structures do not have rounded corners. The method includes forming patterned photoresist over a hard mask so that portions of the hard mask are exposed over a portion of a cell region and over a portion of a periphery region, and then removing the exposed hard mask layer in the periphery region while removing a portion of the exposed hard mask layer in the cell region. A trench having rounded corners is then partially formed in the periphery region and more of the hard mask layer is removed in the cell region, before the trench in the periphery region is deepened while a trench in the cell region is formed.

Abstract: A method of forming a dielectric layer is provided. A first dielectric layer is formed on a substrate having metal layers formed thereon. The first dielectric layer includes overhangs in the spaces between two neighboring metal layers and voids under the overhangs. The first dielectric layer is partially removed to cut off the overhangs and expose the voids and therefore openings are formed. A second dielectric layer is formed on the dielectric layer to fill up the opening.

Abstract: The invention is directed to a method for manufacturing a non-volatile memory. The method comprises steps of forming a stacked gate structure over a substrate, wherein the stacked gate structure is composed of, from the bottom to the top of the stacked gate structure, a first dielectric layer, a charge storage layer, a second dielectric layer, a conductive layer and a cap layer. A source/drain region is formed in the substrate. A protective layer is formed on the sidewall of the stacked gate structure. An etching process is performed to remove the cap layer, wherein, in the etching process, the cap layer and the protective layer have different etching rate.

Abstract: Shallow trench isolation structures are simultaneously fabricated such that ones in a cell region have first-type features and others in a periphery region have second-type features. The first-type features can be rounded edges or can be first depths and widths, and the second-type features can be unrounded edges or can be second depths and widths which are different from the first depths and widths. The method includes forming patterned photoresist over a hard mask over portions of a cell and a periphery region, and removing the exposed hard mask layer in the periphery region while removing a portion of the exposed hard mask layer in the cell region. A trench is then partially formed in the periphery region and more of the hard mask layer is removed in the cell region, followed by the trench in the periphery region being deepened while a trench in the cell region is formed.
