Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14139-2009 "silicon epitaxial wafer". This standard is compared with GB/T 14139-2009, except for editorial changes. The main technical changes are as follows. --- Revised the scope of application, "This standard applies to n-type epitaxial layers (N/N) grown on N-type silicon polished wafer substrates and at p A homogenous silicon epitaxial wafer of a P-type epitaxial layer (P/P) grown on a silicon-polished substrate. Products are mainly used to make silicon semiconductors Device. Other types of silicon epitaxial wafers can be referred to. "" This standard applies to N-types with a diameter of not more than 150mm. And silicon epitaxial wafers grown on P-type silicon polished wafer substrates (see Chapter 1, Chapter 1 of the.2009 edition). --- GB/T 12962, GB/T 14145, YS/T 24 have been deleted from the normative reference documents, and GB/T 1550 has been added. GB/T 1555, GB/T 14844, GB/T 19921, GB/T 24578, YS/T 28, SEMIM85 (see Chapter 2,.2009) Chapter 2 of the annual edition). --- Added "terms and definitions" (see Chapter 3). --- List the product's grades and classifications separately, and revised the orientation of the grades and the crystal orientation of the epitaxial layer (see Chapter 4,.2009 edition) 3.1). --- Revised the requirements for substrate materials for epitaxial wafers (see 5.1, 3.2 of.2009 edition). --- Increased the conductivity type, crystal orientation requirements, test methods, inspection rules, etc. of the epitaxial layer (see 5.2.1, 5.2.2, 6.1, 6.2, 7) chapter). --- Epitaxial layer resistivity is revised from the central resistivity to the average resistivity, and the resistivity, resistivity allowable deviation and radial resistance are revised. Rate change requirements (see 5.2.3,.2009 edition 3.3). ---The thickness of the epitaxial layer is revised from the center thickness to the average thickness, and the requirements for thickness, thickness tolerance and radial thickness variation are revised. (See 5.2.4, 3.4 of the.2009 edition). --- Increased the vertical resistivity distribution of the epitaxial layer and the transition zone width requirements, test methods, inspection rules, etc. (see 5.2.5, 6.5, 7) chapter). --- Revised the requirements for the dislocation density of the epitaxial layer, revised from "not more than 500/cm2" to "should be no more than 50cm-2" (see 5.2.6, 3.5.1 of the.2009 edition). --- Increased surface metal requirements, test methods and inspection rules (see 5.2.7, 6.7, Chapter 7). --- Removed the requirement for large defects (see 3.6.1 of the.2009 edition). --- Removed "surface defect area refers to the silicon epitaxial wafer with a diameter of not more than 76.2mm to remove the edge 2mm annular area, diameter 100mm, 125mm and 150mm silicon epitaxial wafers remove the entire surface of the 3mm annular region of the edge" (see.2009 edition) 3.6.2). --- Removed "surface spot defects including nails, adhering particles, protrusions, inclusions, hillocks and pyramids in accordance with GB/T 14264. Particles that can be removed using cleaning techniques are not point defects (see 3.6.3 of the.2009 edition). --- Removed "Blinding" means that the edge of the epitaxial wafer has a defect depth greater than 0.3 mm in the radial direction. The maximum chipping radial depth is not More than 0.5mm, the maximum perimeter length of the cumulative collapse is no more than 2.5mm" (see 3.6.4 of the.2009 edition). --- Removed the definition of "fog see GB/T 14264" (see 3.6.5 of the.2009 edition). --- Removed "stains including stains, gloves, dust, smudges and solvent residues" (see 3.6.6 for the.2009 edition). --- Increased the requirements for group approval and inspection items (see 7.2, 7.3). ---Modified packaging requirements (see 8.1.1, 6.1.1 of the.2009 edition). --- Added order form (or contract) content (see Chapter 9).
