APPENDIX A SAFETY REQUIREMENTS
•Any tester, equipment, or tool used at any production step, or for any manipulation of semiconductor devices, have its shield connected to ground.
•The product must be placed on a conductive table top, made of steel or clean aluminum, or covered by an antistatic surface (superficial resistivity equal to or
higher than 0.5 MΩ/cm2), grounded through a ground cable (conductive cable from protected equipment to ground isolated with a 1 MΩ resistor placed in
series). All manipulation of finished goods must be done at such a grounded worktable.
• The worktable free of all
•An antistatic floor covering grounded through a conductive ground cable (with serial resistor between 0.9 and 1.5 MΩ) should be used.
•It is recommended that you wear an antistatic wrist or ankle strap, connected to the antistatic floor covering or to the grounded equipment.
•If no antistatic wrist or ankle strap is worn, before each manipulation of the
•It is recommended that antistatic gloves or finger coats be worn.
•It is recommended that nylon clothing be avoided while performing any manipulation of parts.
