Introduction

1. Background and significance of standard formulation

GB/T 33774-2017 "Propylene Gas for Electronic Industry" was formulated to meet the needs of the semiconductor technology field. This standard specifies the technical requirements, test methods, packaging, marking, storage and transportation, and safety of propylene to ensure the high-quality application of propylene in the electronics industry.

2. Comparison of standard frameworks

Dimensions GB/T 33774—2017 Comparison of relevant standards
Technical requirements Propylene purity ≥ 99.99% (volume fraction), nitrogen, oxygen and other impurities content strictly controlled Better than ordinary industrial gas standards
Test methods Adopt advanced measurement technologies such as gas chromatography and cavity ring-down spectroscopy In line with international standards
Packaging and safety Comply with GB/T 5099, GB/T 5100 stipulates that it is recommended to use the CGA510 bottle valve connection method Strengthen the safety management requirements for hazardous chemicals

3. Implementation suggestions

Case study: Application of propylene in semiconductor manufacturing

In the semiconductor manufacturing process, high-purity propylene is used for chemical vapor deposition (CVD) and etching processes. For example, when preparing silicon nitride film, propylene as a reaction gas must meet the technical requirements of GB/T 33774-2017 to ensure the quality of the film and stable operation of the equipment.

Implementation suggestions:

  • Suppliers should strictly follow the standards for production and testing
  • The user side should establish a standard compliance verification process
  • Strengthen safety management during storage and transportation
