Vista Residence (www.vista123.com): ten actions of: from sand to chip - see Easy methods to Make the processor

can be stated the central processing unit (CPU) is the modern Social quick operation from the power source, in any digital system may be found around the microchip from the figure, however it was also dismissed, the processor, this factor is no technical content, but a pile of sand within the aggregate only. Is not it? Intel today introduced a large amount of exhibit information, showing in detail the chip from the sand for the entire procedure, straightforward or not see at a glance.
merely, the processor might be roughly divided in to the sand within the manufacturing process of raw supplies (quartz), silicon ingots, wafers, lithography (offset printing), etching, ion implantation, steel deposition, steel layer, interconnect, wafer testing and cutting, the core package, class testing,Office 2007 Ultimate, packaging marketplace, and many other actions,Microsoft Office Pro 2010, and inside every action of the procedure and includes far more detail.


below to mix graphic, step by step examine:



sand: Silicon will be the 2nd plentiful factor inside the crust , and immediately after the sand oxygen (in particular quartz) include up to 25% from the silicon to silicon dioxide (SiO2) inside the type, which is the basis for that semiconductor production business.


silicon melting: 12 inches / 300 mm wafer level, the exact same below. Obtained by multi-step purification for silicon semiconductor manufacturing good quality, generic digital grade silicon (EGS), an typical of every million silicon atoms within the most one impurity atom. This diagram shows how the purification via the melting of silicon crystals are huge, the resulting ingot is (Ingot).


monocrystalline silicon ingots: the general basic cylindrical, weighing about 100 kg of silicon purity of 99.9999%.

silicon ingot cutting: just one horizontal reduce into circular silicon , that's, we typically say that the wafer (Wafer). By the way, this will be the subsequent spherical wafer know why, perfect?


Wafer: Following cutting out the wafers immediately after polishing will become practically perfect, even when the mirror surface. The truth is, Intel itself does not produce the wafers, but from a third party semiconductor companies to buy goods there, after which use their very own production line for further processing, such as the now mainstream 45nm HKMG (high-K metal gate.) It's really worth mentioning that, Intel organization was founded with all the wafer dimensions is only 2 inches / fifty mm.

photoresist (Picture Resist): proven in blue is poured within the wafer throughout rotation towards the photoresist liquid, comparable towards the sort of standard movie manufacturing. Shop photoresist wafer rotation makes it possible for incredibly thin, quite flat.


lithography: photoresist layer followed by mask (Mask) was uncovered to ultraviolet (UV) beneath, grow to be soluble, comparable to the chemical reactions that happen throughout Press the mechanical film camera modifications the minute the shutter. Pre-designed mask on the printed circuit pattern, via which shines ultraviolet photoresist layer,Office 2007 Professional Plus Key, every layer will kind a microprocessor circuit style. In common, the circuit pattern to the wafer from the mask pattern is one-fourth.


lithography: the resulting nano-sized transistors to the 50-200 level. A wafer may be cut out of tons of processors, but the view from here down to one,Office Pro Plus 2010, and exhibit the right way to make transistors and other components. The equivalent of switching transistor to control the present direction. Now the transistor is so little that a needle are going to be able to place down about 30 million.
third phase of a photo





photoresist dissolution: the coverage to ultraviolet lithography lithography below glue is dissolved away, leaving the patterns and cleared to the exact same mask.


etching: using chemical substance is dissolved out of uncovered elements from the wafer, while the remaining photoresist protects the part should really not be etched.


eliminate photoresist: etching is accomplished, resist the mission declared completed, all distinct following the developed circuit pattern may be observed.

resist: resist doused once more (blue component), then lithography, and wash exposed elements with the remaining photoresist is used to protect that part of ion implantation isn't materials.


ion implantation (Ion Implantation): in a vacuum method, by means of the accelerated use to ion irradiation doping atoms (injection) of strong materials, which was injected within the Regional formation of a special injection layer, and alter the conductivity of silicon area. Immediately after the electric field acceleration, the velocity of ion implantation could be extra than thirty million km per hour.


photoresist elimination: ion implantation is finished, the photoresist was taken out, and to the area (green) has also been doped into several atoms. Be aware that this time the green and distinctive from before.

transistors in place: At this point, the transistor has long been fundamentally completed. Inside the insulation material (magenta) around the 3 holes etched, and stuffed with copper to interconnect with other transistors.


Plating: plating a layer of copper sulfate around the wafer, the copper ion deposition towards the transistor. Copper ions from your cathode (anode) to unfavorable (cathode).


copper layer: Soon after plating, copper ions deposited on the wafer surface, forming a skinny copper layer.

polishing: polishing off the excess copper, which is the polished wafer surface.


metal layers: the transistor stage, the combination of the six transistors, about 500 nm. Complex formed amongst the distinct transistor interconnect metal layer,Microsoft Office Standard, based on the certain layout from the unique requirements from the corresponding processor performance. Chip appear irregular easy surface, but actually could possibly include twenty multi-storey complex circuits might be witnessed right after amplification circuit network is incredibly complex, multi-layer shaped like a futuristic highway method.

wafer testing: the kernel degree, about 10 mm / 0.five inch . The picture is a partial wafers, being the first practical test, employing the reference circuit pattern, and each chip had been in comparison.


wafer slices (Slicing): wafer-level, 300 mm / twelve inches. The wafers into pieces, every piece is actually a processor core (Die).


discarded faulty kernel: wafer stage. The test defects discovered throughout a kernel abandoned, leaving intact for the next stage.

eighth stage of photo





single kernel: kernel level. Wafer was cut from a single core, exactly where the present will be the core of Core i7.


Bundle: package-level, twenty mm / 1 inch. Substrate (substrate), the kernel, the warmth sink stacked with each other to kind the way in which we see the processor. Substrate (green) is equivalent to a base, and for your processor core gives electrical and mechanical interface with all the Pc quickly interact with other parts with the method. Heat sink (silver) is accountable for cooling the core.


Processor: At this time the processor has to become total (this is actually a Core i7). The world's most clear space made products are basically one of the most complex is the outcome of many steps can be achieved, right here only display a few of the essential actions.

the ninth stage of the picture





stage test: the final test, can identify each and every 1 The important thing attributes with the processor, including greatest frequency, power usage, heat, and so forth., and figure out the degree of the processor, for instance, made the most high-end Core i7-975 Serious, or the low-end Core i7-920.


Packing: According to the degree of the check outcomes might be the very same level of processors delivered together.


retail packaging: production, testing finished batch delivered for the OEM processor or producer, or around the packaging box to enter the retail marketplace. Core i7 is the situation here.
