Aluminum is the most common material for metal interconnects in semiconductor chips. The metal adheres well to the oxide layer (silicon dioxide) and is easily workable. That said, aluminum (Al) and silicon (Si) tend to mix .A metal gate, in the context of a lateral metal–oxide–semiconductor (MOS) stack, is the gate electrode separated by an oxide from the transistor's channel – the gate material is made from . For decades, aluminum interconnects were the industry standard. To create these interconnects, a layer of aluminum was deposited. Then, the metal was patterned and etched, and insulating material was deposited to . Aluminum (Al) has been the material of choice for metallization for a significant period since it meets these requirements. By alloying aluminum with small percentages of silicon and copper (known as AlSiCu), some properties can be slightly improved.
Polysilicon, refractory metal silicides (MoSix, TaSix, WSix, and TiSix), aluminum, and copper are used in gates and interconnects (Table 10.2). Table 10.2: Possible metallization choices for integrated circuits. Aluminum on silicon or silicide can lead to deleterious metallurgical interaction. In this final episode of our series on front-end processes, we will introduce the process of metallization which connects semiconductor devices using metals such as aluminum and copper. As these interconnections provide power and enable the chip’s operation, they highlight the significance of metallization in semiconductor manufacturing.
In usual VLSI fabrication process, why was aluminum used for metal layers although copper and gold conduct better? What leads to trending toward copper for metal layers in recent years instead of aluminum?The use of pure aluminum leads to a diffusion of silicon into the metal. The semiconductor reacts with the metallization at only 200–250 °C. This diffusion of silicon causes cavities at the interface of both materials which are then filled by aluminum.Aluminum fulfills the requirements in electrical toughness and resistance against cor-rosion only partial. Metals like silver or copper have better properties, however, these metals are more expensive and cannot be etched in dry etching this easily. The use of pure aluminum leads to a diffusion of silicon into the metal.The wiring of an integrated circuit can take up to 80 % of the chip's surface, that's why techniques habe been developed to stack the wiring on top of the wafer in multiple layers. The amount of wires with only one additional layer can be reduced about 30 %.
