"software" refers to parts of the computer which do not have a material form, such as programs, data, protocols, etc. software is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built. computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. it is often divided into system software and application software computer hardware and software require each other and neither can be realistically used on its own. when software is stored in hardware that cannot easily be modified, such as with bios rom in an ibm pc compatible computer, it is sometimes called "firmware".

in reactive-ion etching (rie), the substrate is placed inside a reactor, and several gases are introduced. a plasma is struck in the gas mixture using an rf power source, which breaks the gas molecules into ions. the ions accelerate towards, and react with, the surface of the material being etched, forming another gaseous material. this is known as the chemical part of reactive ion etching. there is also a physical part, which is similar to the sputtering deposition process. if the ions have high enough energy, they can knock atoms out of the material to be etched without a chemical reaction. it is a very complex task to develop dry etch processes that balance chemical and physical etching, since there are many parameters to adjust. by changing the balance it is possible to influence the anisotropy of the etching, since the chemical part is isotropic and the physical part highly anisotropic the combination can form sidewalls that have shapes from rounded to vertical.
