Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of microfabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The one main criterion of MEMS is that there are at least some elements having some sort of mechanical functionality whether or not these elements can move. In other words Microsystems are miniaturized integrated systems in a small package or more specifically, micro-sized components working together as a system and assembled into a package that fits on a pinhead.

6.1. thermal oxidation 1,2.micro tech,2013
Thermal oxidation is a process used to grow silicon dioxide films on silicon substrates. It involves heating silicon in an oxygen-containing environment to form a stable silicon-dioxide layer. The growth rate of the oxide layer follows a Deal-Grove model based on diffusion and reaction kinetics. While this model accurately describes thicker oxide growth, additional terms are needed to model the initially faster growth rate of very thin oxides. The oxidation rate depends on factors like temperature, oxidizing ambient, crystal orientation, and dopant concentration.

Micro_Electro_mechanical_system
Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of microfabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The one main criterion of MEMS is that there are at least some elements having some sort of mechanical functionality whether or not these elements can move. The term used to define MEMS varies in different parts of the world. In the United States they are predominantly called MEMS, while in some other parts of the world they are called “Microsystems Technology” or “micromachined devices”.
