Electronic class is globose GB of test of 2 oxidation silicon releases crystal of silicon small pink, carry out next year

A few days ago, by city of the harbor that connect the cloud qualitative check center upholds the national standard that establish " the electron is enclosed with globose crystal of condition of the α in small pink of 2 oxidation silicon the law of test method XRD of content of 2 oxidation silicon " release formally, will carry out on January 1, 2019. The issuance of this standard fill domestic electron is enclosed with globose small pink of 2 oxidation silicon examines the blank of the domain, for the test globose content of 2 oxidation silicon offerred the crystal in small pink of 2 oxidation silicon methodological basis, solved all the time since perplex this industry detect the difficult problem that the method cannot unite.

Crystal of globose silicon small pink 2 oxidation silicon

The electron is enclosed with globose small pink of 2 oxidation silicon is the electronic product such as the transistor radio that make, computer, mobile phone advocate board main composition material. In product production process, crystal ” of impurity of this one “ meets 2 oxidation silicon inevitably impure among them, the influence is globose the purity of small pink of 2 oxidation silicon, affect the performance characteristics of product later period then.

The chemistry of 2 oxidation silicon makes “ crystal with globose small pink of 2 oxidation silicon is consistent, provide extremely puzzle quality, and content is infinitesimal, way of groovy check proved recipe is very hard accurate differentiate come out. ” pledges even cloud harbor city Feng Lijuan of check center vice director introduces, the content of 0.5% can cause “ even if integrated circuit invalidation, produce a business so can from most the ore of 2 oxidation silicon of fountainhead chooses and identify through the sense organ by right of experience, but the effect all often is not like person meaning. ”

Because detect traditionally,the method is not had identify a gender immediately, produce an enterprise to often wait for problem of product occurrence quality to just turn round to oppugn the quality that encloses material, cause quality to control apparent lag, also formed certain product quality venture at the same time.

In daily inspection man the understanding in making reachs an industry the bewilderment that to crystal 2 oxidation silicon examines, qualitative check center organizes even cloud harbor city research of professional team with great concentration, reached “ passes analysis of appearance of X ray diffraction to give different diffractive summit finally, the size of content of 2 oxidation silicon has the area that gives a summit and crystal the conclusion of ” of certain conversion concern.

“ spent 4 years of time, did all sorts of content countless times with standard items proportional experiment, reach correct conversion concerns finally. ” pledges even cloud harbor city Chen Jin of check center director says, expert of “ our organization undertakes the project is proved, get the support of countrywide semiconductor equipment and committee of material standardization technology, obtain GB finally appoint project approving, direct high starting point drafts national level. ”

Harbor of “ Lian Yun is the throughout the country’s biggest 2 oxidation silicon small pink produces base, also be the area that home pursues electronic class silicon the earliest small pink development is developed and be being produced. Yuan Tong of standing deputy secretary-general expresses guild of material of ” China electron, “ comes on stage by the GB that enacts even cloud harbor, can offer for the industry unified and effective before path the qualitative check method that guard a pass, master content of ‘ impurity ’ for a short while, ensure leave factory eligible product, avoid the associated loss of later period.
