Essay On Microfabrication
Microfabrication Introduction Microfabrication is the method of producing small structures of micrometer scales and smaller. It’s one of the important processes in manufacturing because it almost needed in every machine in the industry that involves sensors. There are many things in society that are made of microfabrication for example, electronic engine control, power steering, and much more. It’s used in industry to manufacture things in motor vehicles, and medical application, so there are different sectors that involve microfabrication. The research includes microfabrication methods and how it’s used and the advantages of it, application, and how it’s effect on society, economy and the environment.

Lithography is the procedure used to reveal a coating of resist on the surface of silicon to radiation. Thermal oxidation is silicon surface oxidation to form silicon dioxide layer. Chemical vapor disposition is the establishment of a thin film on the surface of a substrate by chemical reactions. Physical vapor disposition is a material transformed to a vapor phase and condensed onto a substrate surface as a thin film. Electroplating and electroforming is the process in which metal ions in a mixture are accumulated onto a cathode work material. Electroless plating is a deposition in an aqueous solution including ions of the plating metal with no external electric current. Thermal diffusion is a process in which atoms migrate from high concentration region into low concentration region. Ion implantation is an implanting atom of one or more elements in a substrate using a high-energy beam of ionized particles. Wet etching is a purpose of a chemical etchant in aqueous solution to etch away a target material. At last dry etching use an ionized gas to etch a target material

Another source is electric discharge which is light produced when an electrical current passes through air or another, like neon, that produces a glow. Another source is light-emitting diode which is light produced when an electrical current passes through a semi-conductor which controls how well is conducts electricity.

580 Words | 3 PagesManufacturing – within a business the manufacturing department works alongside several other departments such as marketing and purchasing to make sure that they manufacture products efficiently. Manufacturing is generally a long process as detailed designs of products have to be assembled before construction can begin. Manufacturing varies can depend on the organisation type large companies are likely to manufacture products themselves, and they tend to do this on a large scale in order to be able to buy resources in bulk in order to save a substantial amount of money. Small businesses tend to design their own products but may not have the ability to manufacture; therefore they usually hire other companies to manufacture for them - this can be quite costly, so they commonly perform manufacturing on a large scale
Andrew Brassksma Some Lessons From The Assembly Line Thesis
165 Words | 1 PagesNowadays few people realize the value of education. In Andrew Brassksma’s essay,” Some Lessons from the Assembly Line,” describes how a college student understands the value of an education by working as a full-time blue-collar worker during the summer time. Often times, there are people without a proper education who are forced to take unstable and low-paying jobs to support themselves or family. But, many people who have access to education do not realize the privilege it is and often times take it for granted. In Andrew Brassksma’s essay,” Some Lessons from the Assembly Line”, he puts himself on the same level as other blue-collar workers, and this is significance to the author's purpose because he can appreciate his own situation to the

Some Lessons From The Assembly Line By Andrew Braaksma
1175 Words | 5 PagesWorking in a physical labor job may seem like an easy way to make money during the summer for students but in the article "Some Lessons From the Assembly Line" written by Andrew Braaksma and published in 2005 he discusses many reasons why his time working as a temp worker in a factory was "anything but a vacation" (Braaksma 2005). The plush lifestyle of a student with lax, customized schedules, haphazard homework attempts, and a rich social environment is a walk in the park compared to what those that work these jobs endure year-round. In two months, Mr. Braaksma learned hard lessons about what hard work entails and the fragile nature of factory jobs. They can be gone in the blink of an eye. An experience like this is vital in giving real-world

Electrolysis In Chemistry Ia
2800 Words | 12 PagesChemistry IA Background information: Introduction: Electrolysis it’s a chemical process that when you pass an electric current into a solution or a liquid that contains ions to separate substances back to their original form. The main components that are required for electrolysis to take a place are: Electrolyte: it’s a substance that when dissolved in water it ionize and then it will contain free moving ions and without these moving ions the process of electrolysis won’t take place. Direct current (DC): This current provides the energy needed to discharge the ions in the electrolyte Electrodes: it’s an object that conducts electricity and it’s used in electrolysis as a bridge between the solution and power supply. A great example

Samsung Manufacturing Strategy: Process Strategies
732 Words | 3 PagesProcess Strategies The process strategies, for such a large manufacturing company, would need to be varied. The production process type would be determined by the product life cycle stage at that time (Thayer 2004).Product life cycles for items such as smartphones and tablets do not generally follow the standard life cycle stages. The maturity stage can be interrupted by discontinuation or irrelevance of a technology, which recommences the cycle (Giachetti & Marchi 2010). Incidentally, during the product life cycle of these items, a cyclic improvement of both process and product is required to stay in contact with market changes.
