Here are just a few devices that depend on microchips: Now and then I note the chemicals or minerals used in the process to give you an idea of the complexity. Silicon wafers are the platform for microprocessors used in transistors, power and RF devices, dynamic random access memories dram , and microprocessors.
There are many ways to make them. The more complex microprocessors require much more processing and materials often layering is done with diamonds, Si-Ge, and other materials, like a complex submarine sandwich that might include gallium arsenide, indium phosphide and antimonide, Si-Ge. Within a chamber having a controlled atmosphere to grow the silicon crystals using very careful temperature control.
Make interconnect with copper: A mold is coated with liner and seed layers, then copper is electrochemically poured in, with excess removed in a polishing step, and finally the surface is capped with a dielectric material to protect the copper often with a plasma-enhanced chemical vapor deposition. Because as devices shrink to the submicron level, circuit performance has encountered problems that can slow it down, and this is solved by applying silicides, which ideally have low resistivity, easily form thin films, withstand chemicals and high temperatures, adhere well to other layers, is smooth, and much more.
There are many possible compositions of silicides, each with their strengths and weaknesses. An intricate and central feature of making semiconductor devices. Plasma chambers etch or deposit thin films of material. Etching needs a high-density plasma that generates ions which remove atoms of material.
Deposition is similar except coating is the objective. Chemical etch is done in high-pressure conditions. Vacuum technology Measurement Equipment required: Force Displacement Gauges liquid level barometer, U-Tube manometer, McLeod Gauge, Bourdon-tube gauge, diaphragm gauge , Capacitance Manometers, Thermal Transfer Gauges thermocouple gauge Pirani gauge, convection-enhanced Pirani gauge , Ionization Gauges hot cathode ionization, cold cathode ionization, Partial Pressure analyzers, Residual gas analyzers.
Vacuum creating equipment required: Primary vacuum pumps oil sealed rotary vane mechanical, dry diaphragm, scroll, screw, sorption pumps.
Flanges with demountable seals to connect to vacuum vessel, valves to control the flow of gas in and out, feed-throughs allow for mechanical motion, radiation, or fluids in and out of vacuum vessels to manipulate objects inside the vacuum.
The intermediate steps between design and wafer, the stencils used to print images onto the semiconductor material. Design data is conditioned to generate instructions for the pattern generator to use to print the mask features, then converted to a file format acceptable to the pattern generation tool. Enormous computer resources are needed for this complex step. As chips shrink, exponentially larger pattern files are required to cope. The generated files are so large that transferring them from the design center to the photomask vendor taxes networks.
The design data are printed on resist-coated photoblank with electron beam ebeam systems in a high vacuum that take 10 to 18 hours, or with laser-beamed systems using deep ultraviolet lasers in 5 to 9 hours. Atlas laser systems split the laser into 32 separate beams that are raster scanned across the mask with a facet rotating cylindrical mirror. After patterning, this step removes standing waves formed from reflections of the substrate surface since these can degrade the resist image leading to poor uniformity.
The exposed resist is removed by solvents, and surfactants improve the wetting of the resist, then developers are added with puddle processes left on top for a while and then rinsed off, or sprayed on.
After the exposed resist is removed, the underlying chrome is etched with wet processes using powerful acids or dry etch methods that use gases such as chlorine in a plasma induced by radio frequency energy. Resist removal and cleaning: After the pattern is etched into the chrome of the photomask, unexposed resist is removed with strong acids.
Quality assurance to make sure mask features were printed at the proper size, defect inspections. Final Cleaning and pellicle mounting: File sizes for design data ranged from 1. Data preparation times averaged 6. Fabrication processes of an integrated circuit fall into 3 categories: Conductors and insulators are used to connect and isolate transistors. Doping allows the conductivity of the silicon to vary with voltage.
The patterns are written with a photoresist lithography and etch transfer step usually up to 30 times to build the millions of transistors and many wires. Each pattern printed is aligned to the previous pattern and slowly the conductors, insulators, and doped regions are built up to form the final device.
Optical lithography is a photographic process which exposes the photoresist a light sensitive polymer and developed to form 3D images on the substrate. Substrate Preparation improves adhesion of photoresist material to substrate by cleaning, baking at C or using chemicals to get rid of water, and adding an adhesion promotor.
This has to be very carefully controlled to get the right thickness and uniformity which varies depending on the substrate material.
Dry the photoresist after the spin coat process by removing excess solvent using a hot, high-mass metal plate in a vacuum. Once exposed, the photoresist must be developed with tetramethyl ammonium hydroxide poured on a rotating wafer or sprayed on. Dozens of ion implantation steps are usually required that very precisely plant the right amount of dopants ions at just the right spot.
Implanter beamlines also need a mass analysis devise to provide momentum dispersion and transverse focusing of the ion beams. There are high-current beamlines, high-energy beamlines, and medium current beamlines.
High-current and energy architectures use a multi-wafer batch processing chamber where many wafers can be implanted at once using a spinning disk at rpm of the wafers across a fixed-spot beam. Single wafer processing just ipmlants a single wafer. Postimplant thermal annealing repairs the crystalline structure of the wafer from the damage created during implantation and electrical activation of the new dopant ions. This is done usually with isothermal lamp or hot-walled furnaces. Wet chemical etching reacts with the substrate to produce soluble products that can be washed off.
I formati appositamente ideati per gli ebook hanno generalmente il vantaggio di essere adatti a piattaforme dotate di meno risorse hardware rispetto ai computer desktop.
Spesso infatti prevedono la riduzione delle dimensioni del testo e si adattano meglio ad essere visualizzati sui piccoli schermi dei dispositivi portatili. Questo tipo di formato presenta diversi svantaggi tra cui: Libri che si possono toccare, libri che si possono odorare, libri dai quali possiamo dipendere. Infatti, analizzando i dati, emerge che in Italia, su 19 mila ebook, ben 15 mila sono disponibili nella versione pirata.
Coloro che caricano sul web internet illegalmente, non agiscono in maniera disinteressata, ma per guadagnarne. Chi mette on line file riceve denaro dal servizio hosting, in base alla dimensioni e alle migliaia di scaricamenti. Inoltre, ne ricavano profitto le compagnie pubblicitarie che forniscono le inserzioni ai servizi di hosting e i provider di servizi finanziari attraverso cui i pagamenti possono avvenire anonimamente.
La ricerca, condotta in Uk da Kantar Media, rivela che i consumatori di ebook sono quelli che hanno pagato in numero maggiore per i contenuti di cui hanno usufruito rispetto ai consumatori di altro tipo film, musica, videogames ecc. Contribuisci a migliorarla secondo le convenzioni di Wikipedia.
