Description / Abstract:

This Specification covers ordering information and certain requirements for the two classes of crystalline silicon materials for photovoltaic applications that are recognized: single crystal and multicrystalline.

NOTE 1: In the single crystal form, one crystallographic orientation describes the whole wafer and in the multicrystalline case there is more than one crystallographic orientation present.

A complete purchase specification requires that various physical properties be specified along with test methods suitable for determining their magnitude. The specification format in this Standard provides a comprehensive listing of such properties and available associated test methods. 

System International (SI) units are used throughout.

NOTICE: SEMI Standards and Safety Guidelines do not purport to address all safety issues associated with their use. It is the responsibility of the users of the documents to establish appropriate safety and health practices, and determine the applicability of regulatory or other limitations prior to use.

Purpose 

This Specification covers the requirements for silicon wafers for use in photovoltaic (PV) solar cell manufacture. To permit common processing equipment to be used in multiple fabrication lines, it is essential for the wafer dimensions to be standardized.

This Specification provides standardized dimensional and certain other common characteristics of silicon wafers based on currently widely used sizes for photovoltaic applications.

This Specification also provides a tabular specification format for order entry so that relevant nonstandardized wafer characteristics and extensions of wafer sizes for research, development, and new requirements can be easily and consistently specified in commercial transactions.
