Title:
DISCHARGE PREVENTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/142133
Kind Code:
A1
Abstract:
A conductive structure in an environment exposed to high energy electrons and an
electronic device mounted on the surface of the conductive structure are prevented from
discharging due to potential rise in the negative direction by the flowed-in negative
charges. An insulating tape attached to the surface of the conductive structure
is bored, and a conductive adhesive agent is applied to the exposed surface of
the conductive structure. Subsequently, an insulating film is attached on the
conductive adhesive agent and is so formed as to expose part of the conductive adhesive
agent to the outside. Upon encountering high energy electrons, the insulating
film is charged and a high electric field is applied to the conductive adhesive
agent, so that electrons are emitted from the conductive adhesive agent by electric
field electron emission, thereby preventing the potential rise of the conductive
structure in the negative direction.
