Abstract: A device includes a first semiconductor fin extending from a substrate, a second semiconductor fin extending from the substrate, a dielectric fin over the substrate, a first isolation region between the first semiconductor fin and the dielectric fin, and a second isolation region between the first semiconductor fin and the second semiconductor fin. The first semiconductor fin is disposed between the second semiconductor fin and the dielectric fin. The first isolation region has a first concentration of an impurity. The second isolation region has a second concentration of the impurity. The second concentration is less than the first concentration. A top surface of the second isolation region is disposed closer to the substrate than a top surface of the first isolation region.

Abstract: A method includes forming a first plurality of fins in a first region of a substrate, a first recess being interposed between adjacent fins in the first region of the substrate, the first recess having a first depth and a first width, forming a second plurality of fins in a second region of the substrate, a second recess being interposed between adjacent fins in the second region of the substrate, the second recess having a second depth and a second width, the second width of the second recess being less than the first width of the first recess, the second depth of the second recess being less than the first depth of the first recess, forming a first dielectric layer in the first recess and the second recess, and converting the first dielectric layer in the first recess and the second recess to a treated dielectric layer.

Abstract: A cosmetic container for dispensing a soft cosmetic mass is disclosed. The container comprises two mated upright chambers, each chamber including a top external threaded section and a protrusion in an underside, two push rods each including an enlarged knob having inner threads threadedly secured to the threaded section, and a top spring biased trigger put on the push rods, a shroud including two top apertures for permitting the push rods to insert through and two opposite inner latches in a bottom, the latches being disposed under bottom edges of the knobs for supporting and fastening, a bottom disk including two spaced holes with the protrusions matingly engaged therein, and a cap. In use an equal amount of soft mass can be squeezed out of both chambers in one dispense.
