Semiconductor industry: The importance of Anelva target

The sputtering target materials can be divided into metal target (pure metal gold, aluminumtitanium, etc.), alloy target (aluminum-scandium alloy, cobalt-aluminum alloy, aluminum-titanium alloy, etc.) and ceramic compound target (oxides, nitride, silicides, etc.) according to their different chemical compositions; when it comes to different application fields, it can be categorized into semiconductor target, planar display target, solar cell target, and other target materials. Anelva target refers to the sputtering target used in semiconductor industry.

Although the proportion of Anelva target is just about 3% among all the sputtering targets, it cannot be denied that its application in semiconductor chip market is important and irreplaceable. There are generally two kinds of Anelva target: wafer materials and packaging materials. Today we mainly focus on wafer manufacturing materials because they have relatively high technical barriers than the other.

The inner part of the semiconductor is composed of tens of thousands of meters of metal wiring, and the sputtering target material is the key consumption material for making these wiring. In other words, the Anelva target is the core of semiconductor wafer manufacturing. Since the chip is elaborate, it has high requirements for sputtering target material used in the manufacturing process. Generally, the purity of the target material is over 99.999%.

Semiconductor wafers are the basic material for manufacturing chips (as shown below). It is small but complicated. The production of wafer mainly involves 7 kinds of semiconductor materials and chemicals. The most important raw material for semiconductor integrated circuits is silicon, which is widely found in rocks and gravel in the form of silicate or silicon dioxide in nature. The manufacturing process of silicon wafers can be divided into three basic steps: silicon purification, monocrystalline silicon growth, and wafer formation. Apart from silicon, the manufacturing process of 200mm (8-inch) and below wafers is usually mainly made of aluminum, and the manufacture of 300mm (12-inch) wafer mostly uses advanced copper interconnection technology.

Semiconductor wafer

In conclusion, with more extensive use of semiconductor chips, the demand for aluminum, titanium, tantalum and copper, the four mainstream Anelva target, will also increase. There is currently no alternative to these target materials, either technically or economically, so, as I mentioned before,  they are important and irreplaceable.

What should we do when the target is broken?

For most of the time, people consider the purity, and maybe the shape, of the sputtering target when they are purchasing the target materials. But one thing should not be ignored is the target bonding. Well, you think it unnecessary and costly? Then just think about what to do when your target is broken.broken target

Target bonding is necessary

Maybe you can use a copper plate to stick the broken pieces of the target and then polish the target so that the broken areas have minimum exposure to plasma. The second step is very important because the power would suddenly breakdown to zero when plasma strike to broken area of target. And obviously, the film quality will be affected if breakdown is frequent. Although it may help solve the problem when the target is broken, it is still a remedial measure. To avoid target from breaking, you need to give a target bonding service to the target. It is necessary for those brittle targets, and is not expensive compared with the losses of the broken target.

PVD vs. CVD: What’s the difference?

PVD vs. CVD: What’s the difference?

In recent years, physical vapor deposition (PVD) and chemical vapor deposition (PVD) have wide applications in various industries to increase the hardness of tools and molds or apply beautiful colors to the products. Thus these two methods are considered as the most attractive surface coating technologies. Then, using the example of cutting tools, let’s make a detailed comparison between these two methods.

Definition

Physical vapor deposition (PVD) uses low-voltage, high-current arc discharge technology under vacuum conditions to evaporate the target and ionize the vaporized material and the gas, and finally make the evaporated material and its reaction deposited on the workpiece.

Discovery and development of tungsten | History of Tungsten

tungsten

The history of tungsten dates back to the 17th century. At that time, miners in the Erzgebirge Mountains of Saxony, Germany, noticed that some of the ore would interfere with the reduction of cassiterite and produce slag. The miners gave the mines some German nicknames: “wolfert” and “wolfrahm”.

How was niobium discovered? | History of Niobium

Last week, we talked about the discovery of Titanium, which raised many interest. So we decide to start a history column, aiming at introducing the discovery of different kinds of metals. If you are a metal lover or history lover, you can follow our website. For previous posts of this column please search the keyword “history”. So let’s get down to the point. Today SAM Sputter Targets will teach you the history lesson of Niobium.

niobium hostorySAM®Niobium, often found in the minerals pyrochlore and columbite, is a silver-gray, soft and ductile rare metal with high melting point. At normal temperature, niobium does not react with air, but it can directly combine with sulfur, nitrogen and carbon at high temperatures to form NbS2, NbN and NbC. Niobium does not react with inorganic acids or alkalis, and is insoluble in aqua regia, but soluble in hydrofluoric acid. Because of its good superconductivity, high melting point, corrosion resistance and wear resistance, niobium is widely used in steel, superconducting materials, aerospace, atomic energy and other fields.

Steel

The main use of molybdenum is to produce various types of steel and alloys. The addition of molybdenum (mainly in the form of ferromolybdenum, molybdenum oxide and calcium molybdate) to a range of steels such as structural steel, spring steel, bearing steel, tool steel, stainless steel and magnetic steel can significantly improve the properties of steel. Molybdenum improves the hardenability, toughness and heat strength of steel and prevents temper brittleness. Molybdenum also improves the corrosion resistance of steel to certain media so that it does not pitting. The addition of molybdenum to the cast iron enhances the strength and wear resistance of the cast iron.
