发明名称 Method for protecting an integrated circuit chip
摘要 The invention concerns a method for protecting integrated circuit chips of a silicon wafer. The silicon wafer is cut so as to disengage the chips from the integrated circuit; and a fluid insulating material is applied on the rear surface of the wafer so as to coat the flanks of each chip of the integrated circuit with a thin insulating layer. The insulating material may be applied by spraying, screen printing, dip coating, casting or any other means. The invention further concerns integrated circuit chips where the flanks are protected by an insulating material to prevent electrical malfunction caused by contact of a conductive material on the flanks of the chips.
