In simple term microelectronics is a part of electronic technology which can be defined as a group of small electronic components assembled in an extremely small and compact form. It is related to study and manufacture of very small discrete electronic devices for designing and components purpose. Microelectronics products are the need of the modern life style. These products can be found in every part of our routine life like in the form of electronics, gadgets, computers, autos, aerospace, education, defense, oil and gas, medical, communications and many mores. By using the various microelectronic techniques like resistors, microelectronics fabrication, capacitors, transistors and microelectronics assembly numerous products can be made of any sizes and forms. These are important steps in the creation of the numerous types of electronic devices used every day all over the world. In these days most silicon wafer suppliers and semiconductor companies are using latest microelectronic technology to implement processes correctly and efficiently and to design and develop smaller, useful, user friendly, faster, and cheaper electronic devices. For any electronic manufacturing company both documentation system and process control accreditations like ISO9001:2008, AS9100 Rev. C and NADCAP AC7120 are necessary.
