SEMI Evaluation Service

SEMI is a safety standard that is applied to industrial equipment such as semi-conductor, FPD, and other related equipment.
It is applied to the equipment that uses chemical substances, X-RAY, and toxic/flammable substances.

QAI Asia engineers, trained with specialized education on seismic resistant design, safety technology for laser and chemical substances,
and tracer gas test, conduct SEMI evaluation.

  • Certification of semi-conductor, LCD display production equipment
  • Certification of SEMI S2, SEMI S6 Tracer gas Test, SEMI F47 Test, SEMI E78 Test
  • Certification of earthquake-resistant design & certification of chemical substance safety
  • Certification of explosive hazard section & certification of blast resistant design

It is a test to assess the performance of displacement system of semi-condoctor
equipment that uses flammable or toxic substances. It conducts evaluation on
enclosures that is installed with displacement system and that may have a leak source
of gas or liquid chemical substances such as valve. QAI ASIA provides advisory to
semi-conductor equipment providers to design in accordance with the common
performance standard through SEMI S6 test and helps users to understand required
conditions of displacement system.


It is a resistance criterion test of instantaneous voltage sag of semi-conductor equipment
proposed by SEMI. It evaluates resistance caused by power fluctuation whether the
semi-conductor equipment is properly operated without malfunction even if there is
a changed circumstance in the industrial site such as instantaneous voltage drop.
It is passed if the tested equipment is properly operated during the F47 test.
