Molybdenum Sputtering Targets For The Semiconductor Industry


1. Description Of Molybdenum Sputtering Targets For The Semiconductor Industry:


Molybdenum is a versatile refractory metal with outstanding mechanical qualities, a low coefficient of expansion, strong thermal conductivity, and exceptionally high electrical conductivity at high temperatures. There are numerous combinations that can be used as sputtering targets, including pure molybdenum targets, molybdenum titanium targets, molybdenum tantalum targets, and molybdenum alloy targets (such as TZM plate).


The materials used for semiconductors include pure metal targets such as tungsten, molybdenum, niobium, titanium, and silicon, additionally to substances like oxides or nitrides. As crucial as the deposition operating parameters that engineers and scientists perfect throughout the coating process are the material selection procedure.

5. Features Of Molybdenum Sputtering Targets For The Semiconductor Industry:


The sputtered coating adheres to the substrate better than conventional deposition techniques, and materials with very high melting temperatures, like molybdenum and tungsten, are very simple to sputter. Additionally, whereas evaporation can only be done from bottom to top, sputtering can be done both ways.


Sputtering targets are frequently rounded or rectangular, although there are also square and triangular options available. The substrate is the item that needs to be coated, and it might be anything from solar cells to optical components to semiconductor wafers. The coating typically ranges in thickness from angstroms to microns. The membrane may consist of a single material or several materials stacked in layers.


High purity, high density, fine, and consistent grain properties are present in molybdenum sputtering targets, resulting in extremely high sputtering efficiency, homogeneous film thickness, and a clean etching surface throughout the sputtering process.
