In MOS devices, polysilicon is generally used for gate metallization. With this metal in contact with gate oxides, devices characteristics and processes are unaltered. To have low resistance at gate and interconnection level, polysilicon is replaced by polysilicon /refractory silicides.Ingredients of a semiconductor device fabrication process 1. bulk material, e.g. Si, Ge, GaAs 2. dopants to create p-and n-type regions 3. metallization to make contacts 4. passivation to protect the semicond uctor surfaces from electrical and chemical contaminants Practically all semiconductor devices are fabricated in a planar geometry (very f.Advanced Metallization and Processing for Semiconductor Devices and Circuits II Editors: Avishay Katz, Shyam P.

Metallization is applied either by evaporation or sputtering. Since all of these processes are only to be applied to specifically controlled areas, “masks” are used to expose only selected areas to difusion, ion implantation, or etchants. The patterning is accomplished by photolithography. A photoresist is applied to the surface.In general, DNA metallization has three approaches: chemical reduction, electrochemical deposition and photoreduction. Chemical reduction makes use of reagents such as hydroquinone, dimethylamine borane (DMAB), sodium borohydride, alkaline solution and ascorbic acid to help the reducing of metal ions or nanoparticles.It introduces the basic techniques of defining physical patterns by lithography and etching, changing the doping concentration by ion implantation and diffusion, and depositing thin films over the semiconductor’s substrate. One section describes the techniques of fabricating the important metal interconnection structures. Metallization is the process by which the components of IC’s are interconnected by aluminium conductor. This process produces a thin-film metal layer that will serve as the required conductor pattern for the interconnection of the various components on the chip.
The fabrication of electronic devices requires, among others, metallization for ohmic or Schottky contacts on the GaN. The metallization method chosen for this purpose should fulfil several requirements, including good adhesion of the metal to GaN, the ability to deposit compounds stoichiometrically and the ability to deposit high melting point .
After devices have been fabricated in the silicon substrate, connections must be made to link the circuits together. This process is called metallization. Metal layers are deposited on the wafer to form conductive pathways.
