Origin of the Moore Formula 5, Origin of the Moore Formula

Moore's Law"of"The initiator"He is Gordon Moore, one of the founders of Intel, a well-known chip manufacturer. The rapid development of the semiconductor manufacturing industry from the late 50s to the early years of the 20th century led to:"Moore's Law"of the introduction. (ja&byp/xp|v

As early as 1959, Fairchild, a famous American semiconductor manufacturer, first launched planar transistors, followed by planar integrated circuits in 1961. This planar manufacturing process is based on a very flat silicon wafer and uses a so-called"Lithography"technology to form the components of semiconductor circuits, such as diodes, transistors, resistors and capacitors. Only"Lithography"The accuracy of the components will continue to improve, and the density of the components will also increase accordingly, so that it has great development potential.

Hence the planar craft is considered to be"The entire semiconductor industry keys", which is also the technical basis for the advent of Moore's Law.

At the request of the magazine, Moore predicted what the semiconductor component industry would look like over the next decade. He estimated that by 1975, it would be possible to dense 65,000 components on a single silicon chip with an area of only a quarter of an square inch. He made this inference based on the linear relationship between the complexity of the device (the density of the circuit increases and decreases) and time, as he said:

The impurities at the lowest element** are approximately doubling each year. It is safe to assume that this growth rate will continue in the short term. Even if it's not accelerated.

The rate of growth over a longer period of time should fluctuate slightly, although there are good reasons to argue that it will remain almost constant for at least the next decade. "That's what came to be called"Moore's Law"The original prototype.

Properly speaking, it should be called Moore's Law, not Moore's formula, because it is Moore, the founder of Intel Corporation. Moore's Law in the computer hardware industry and computer principles textbooks all believe that under the same condition, the computing power of computer chips (integrated circuits, i.e., ICs) increases by 1 time every 18 months; The number of transistors on a chip doubles every 18 months.

This prediction was made by Mr. Moore in a 1965 article, in which he also proposed that integrated circuits would lead to the birth of miracles such as home computers, or at least terminals, connected to a computer that would automatically control automobiles and personal portable communication devices. Now, the advent of personal computers and mobile ** confirms Mr. Moore's prediction. Moore's Law was also miraculously confirmed.

In 1971, it was reported that the first operational silicon chip was produced with only 2,300 transistors, and in 2005 a chip containing 1.7 billion transistors was launched, almost at a speed that almost exactly fits the expression of Moore's Law. This huge and rapid development has made the computing power of electronic toys in the hands of children today far greater than that of the National Aeronautics and Space Administration (NASA) moon landing rover in 1969!

However, scientists have warned that Moore's Law will fail, because it is impossible to increase the number of transistors indefinitely with a chip of the same size, despite the fact that nanotechnology has now been developed.

The molar formula is m = m n, where n is the number of particles and m is the number of particlesMolar mass

The amount per unit substance.

The mass possessed by the substance is called the molar mass and is denoted by the symbol m. When the amount of a substance is measured in mol, the unit of molar mass is g mol, which is numerically equal to the atomic mass of the substance.

or molecular mass.

For a compound, its molar mass is fixed. The mass of the substance changes with the amount of the substance. The relationship between the quantity (n), mass (m), and molar mass (m) of a substance is: n=m m.

For a certain pure substance.

The molar mass of the cavity is fixed, while the mass of the substance varies with the amount of matter.

For example, the mass of 1mol O is 32 g, and the mass of 2 mol O is 64 g, but the molar mass of O does not change in any way, or 32 g mol. According to the precise determination of scientific experiments, it is known that the number of carbon atoms contained is about.

The mole calculation formula is n=m m, n=v vm, n=n na, n=cv, pv=nrt, and the volume ratio of the gas is equal to the quantity ratio of the substance at the same temperature and pressure.

At the same temperature and at the same volume, the pressure ratio of the gas is equal to the amount of matter.

Compare. Moore, referred to as Mole, formerly known as gram molecule, gram atom, symbol mol, is the unit of quantity of matter, is the International System of Units.

One of the 7 basic units. Every 1 mole of any substance (microscopic substance, such as molecules, atoms, etc.) contains the Avogadro constant (about a particle.

Molar Calculation (AmountofSubstanceConcentration) Formula:

m（mol/l）＝n（mol）/v（l）

where c(b) represents the concentration of the substance that dissolves the answer.

n represents the amount of solute substance, v represents the volume of solution, unless otherwise specified, then it is considered that the solvent is water. The Si unit of the amount of a substance is mol·m, and the commonly used unit is mol·dm or mol·l.

Mosen's formula defines this lack of beat.

As of 2011, the International Bureau of Weights and Measures defines 1 mole as having a relative atomic mass of 12 grams of carbon-12 (the element carbon.

is 12 atoms) contains the same number of atoms as the system of elementary particles, the amount of which is 1 mole.

So the mass of 1 mole of pure carbon-12 is exactly 12 grams. Mole history and relative atomic mass, Avogadro's constant.

and a series of related concepts related to the history.

The molar formula is m=m nMole (mole), abbreviated as mole, formerly known as gram molecule, gram atom, symbol mol, is the unit of quantity of matter, is one of the seven basic units of the International System of Units. Every 1 mole of any substance (microscopic substance, such as molecules, atoms, etc.) contains the Avogadro constant (about one particle. When using moles, elementary particles should be specified and may be atoms, molecules, ions and other microscopic particles, or specific combinations of these microscopic particles.

About one atom is 1 mole, just like people often say that a dozen refers to 12, and "mole" is just a special unit like "dozen". g) c(carbon-12) contains 1 mole of atoms.

On November 16, 2018, the 26th International Conference on Weights and Measures adopted the resolution "Revision of the International System of Units", officially updating the definition of four basic units, including the international standard unit of mass "kilogram". The new SI system of units uses physical constants to redefine the unit of mass "kilogram", the unit of current "ampere", the unit of temperature "Kelvin", and the unit of quantity of matter "mole". 1 mole is the amount of matter that contains exactly a system of basic units such as an atom or molecule.

The Moore formula isThe formula for calculating the quantity concentration of a substanceThe content of the formula is: the amount of solute = the amount and concentration of solute x the volume of solution n = c·v.

Molar massis the mass of the substance divided by the amount of the substance, the unit is grams per mole, and the molar volume is the volume of the substance divided by the amount of the substance, and the unit is cubic meters per mole. The gram atomic weight, gram molecular weight, and gram molecular volume, which were commonly used in the past, should be abolished.

Molar mass and molar volume are the derived quantities of the quantity of a substance, and the basic unit must be indicated when applied, and the molar mass and molar volume are different for different basic units specified for the same substance.

A brief introduction to other facts about molar mass.

To put it bluntly, molar mass is used relative atomic mass.

Multiply by the number of atoms, and then add the units to it, so that n is equal to m divided by m, which is 32g divided by 32g mol, so n is equal to 1 mol. The mass possessed by a substance per unit of substance is called molar mass and is denoted by the symbol m. When the mass of a substance is measured in grams, it is numerically equal to the relative atomic mass or relative molecular mass of the substance.

1) n = m m, n is the quantity of matter (mol), m is the mass (g), m is the molar mass.

2) n = n ruler destroys na, n is the number of particles, and na is the constant of Aaddro.

3) n=v vm, v is the volume of the gas (l), vm is the molar volume of the gas under certain conditions.

l mol), in the standard case, vm =

4) n=cv, c is the amount concentration of the solute in the solution.

mol l), v is the volume of the solution (l).

The significance of molar mass is the mass of a molar substance. Therefore, molar mass is not calculated, but is an intrinsic property of matter. For example, if one mole of sulfuric acid is 98 grams, then the molar amount of sulfuric acid can be expressed as: 98 g mol

The value of the molar mass of a substance is equal to the formula (molecular weight, atomic weight) of the substance.

etc.). For example, the relative molecular mass of sulfuric acid.

is 98, then the molar mass of sulfuric acid is 98g mol;

Sodium hydroxide. The relative molecular mass of 40 then the molar mass of sodium hydroxide is 40g mol
