Foreword
This Standard modifies and adopts SEMI M16-1103.2003 ?€?Specification for Polycrystalline Silicon?€?. The main differences are as follows.
-- add the technical parameters, such as the grade requirements of phosphine resistivity, boron resistivity, concentration of carbon as well as n-type minority carrier lifetime;
-- add the size range requirements for polycrystalline silicon.
This Standard replaces GB/T 12963-1996 ?€?Polycrystalline Silicon?€?.
Compared with GB/T 12963-1996, the main changes of this Standard are as follows. -- revise the phosphine resistivity grades from 300???€?cm, 200???€?cm, 100???€?cm to be 500???€?cm, 300???€?cm, 200???€?cm;
-- add a term of oxide lamella.
This Standard was proposed by National Standardization Technical Committee for Semiconductor Equipment and Materials.
This Standard shall be under the jurisdiction of Material Technical Committee of National Standardization Technical Committee for Semiconductor Equipment and Materials.
The drafting organization of this Standard. Emei Semiconductor Material Plant. Main drafters of this Standard. Luo Liping, Zhang Huijian and Wang Yan. The previous editions replaced by this Standard are as follows.

Specification for Polycrystalline Silicon
1 Scope
This Standard specifies the product classification, technical requirements, test methods, inspection rules, mark, transportation as well as storage for the polycrystalline silicon.
The polycrystalline silicon, which is manufactured from trichlorosilane or silicon tetrachloride by hydrogen reduction method, is applicable to this Standard. 2 Normative references
The following documents contain provisions which, through reference in this text, constitute the provisions of this Standard. For dated reference, the subsequent amendments (excluding corrigendum) or revisions of these publications do not apply. However, all parties who reach an agreement according to this Standard are encouraged to study whether the latest edition of these documents is applicable. For undated references, the latest edition of the normative document is applicable to this Standard.

6.3 Inspection item
The phosphine resistivity, boron resistivity, n-type minority carrier lifetime, concentration of carbon, structure surface quality and dimension shall be inspected for each batch of product.
6.4 Sample collection and sample preparation
6.4.1 When the supplier is processing the "sample collection" and "sample preparation", the sample collection and sample preparation of phosphine resistivity and boron resistivity shall be carried out according to the requirements of GB/T 4059 and GB/T 4060; the sample collection and sample preparation of section oxide lamella shall be carried out according to the requirements of GB/T 4061. 6.4.2 The sampling scheme for the arbitration shall be agreed by the supplier and purchaser; the sampling location and sample preparation shall be carried out according to 7.4.1.
6.5 Determination of inspection result
If one item of the inspection results is unqualified, then the doubling sampling is required to be carried out for the re-inspection of the unqualified item(s). If it is still unqualified, then this batch of products are deemed as unqualified.
7 Mark, Package, Transportation and Storage
7.1 The polycrystalline silicon shall be packed into a clean polyethylene packaging bag after it is cleaned and dried in a certain way; then the packaging bag shall be packed into a packing box. As for the block-shaped polycrystalline silicon, the net weight of each bag shall be 2000 g??20 g, 5000 g??50 g, 10000 g??100g. Each stick of club-shaped polycrystalline silicon shall be packed independently. It is required to protect the polyethylene packaging bag from breakage while packing, so as to avoid the foreign contamination to the product; the good protection shall be provided in an optimal placing way.
7.2 The wordings or marks such as "Handle with Care", "Keep Away From
Corrosion, Keep Away from Moisture" shall be marked on the packing box, and indicate.
A) Purchaser?€?s name;
B) Product name, designation;
C) Number of packages and net weight of the product;
D) Supplier?€?s name.
7.3 Each batch of product shall be accompanied by a Certification of Quality, and noted with.
A) Supplier?€?s name;
B) Product name and designation;
C) Lot identification mark;
D) The gross weight and net weight of product;
E) Stamps of each inspection result and inspection department;
F) Serial number of this Standard;
G) Date of exit-factory.
7.4 The product shall be loaded and unloaded carefully during the transport process; do not press and shove it, and adopt the vibration-proof measures.
7.5 The product shall be stored in a clean and dry environment.
