BORON TRIBROMIDE SEMI C22-0699 © SEMI 1994, 19991
SEMI C22-0699
GUIDELINE FOR BORON TRIBROMIDE
This guideline was technically approved by the Global Process Chemicals Committee and is the direct
responsibility of the North American Process Chemicals Committee. Current edition approved by the North
American Regional Standards Committee on April 23, 1999. Initially available on SEMI OnLine May 1999;
to be published June 1999. This document replaces SEMI C7.17 in its entirety. Originally published in 1994.
1 Purpose
1.1 The purpose of this document is to standardize
requirements for boron tribromide used in the
semiconductor industry and testing procedures to
support those standards. Test methods have been shown
to give statistically valid results. This document also
provides guidelines for grades of boron tribromide for
which a need has been identified. In the case of the
guidelines, the test methods may not have been
statistically validated yet.
2 Scope
2.1 The scope of this document is all grades of boron
tribromide used in the semiconductor industry.
3 Limitations
3.1 None.
4 Referenced Documents
4.1 None.
5 Terminology
5.1 None.
6 Physical Property (for information only)
Clear Colorless Liquid Density at 20°C2.54 g/mL
7 Requirements
7.1 The requirements for boron tribromide for Tier A
are listed in Table 1.
8 Grade 1 Procedures
8.1 This section does not apply to this chemical.
9 Grade 2 Procedures
9.1 This section does not apply to this chemical.
10 Grade 3 Procedures
10.1 This section does not apply to this chemical.
11 Grade 4 Procedures
11.1 This section does not apply to this chemical.
12 Grade 5 Procedures
12.1 This section does not apply to this chemical.
13 VLSI Grade Procedures
13.1 This section does not apply to this chemical.
14 Tier A Procedures
14.1 Standardized test methods are being developed
for all parameters at the purity levels indicated. Until
standardized test methods are published, test
methodology shall be determined by user and producer.
The Process Chemicals Committee considers a test
method to be valid only if there is a documented
recovery study showing a recovery of 75 - 125%.
Recovery is for a known sample spike at 50% of the
specified level.
15 Tier B Procedures
15.1 This section does not apply to this chemical.
16 Tier C Procedures
16.1 This section does not apply to this chemical.
17 Tier D Procedures
17.1 This section does not apply to this chemical.
