SPUTTERING SYSTEM

A sputtering system is suitable for sputtering a surface to be sputtered having sections. Each section has a projection height. The sputtering system includes a supporting plate, a sputtering array, and a controller. The sputtering array is arranged on the supporting plate. The sputtering array includes sputtering units. Each section corresponds to at least one of the sputtering units. Each sputtering unit has a driving shaft and a target. The target faces the surface to be sputtered. The controller is electrically connected the driving shaft. The driving shaft drives the target to move relative to the surface to be sputtered. The controller controls a distance between each sputtering unit and the corresponding section of the sections in the direction of the projection height to satisfy a given condition.

Sputtering targets and devices including Mo, Nb, and Ta, and methods

Sputtering targets including molybdenum, niobium and tantalum are found to be useful for sputtering films for electronic devices. Sputtering targets with about 88 to 97 weight percent molybdenum show improved performance, particularly with respect to etching, such as when simultaneously etching an alloy layer including the Mo, Nb, and Ta, and a metal layer (e.g., an aluminum layer). The targets are particularly useful in manufacturing touch screen devices.
