■ Patent Coulomb-Force E-Chuck
Advanced technology encloses the electrical field in the E-Chuck. E-Chuck becomes a move-free carrier. After adhesion setting, Move-Free Supporter can disconnect the power supply and still keep adhesion force. Move-Free support can support hardness or shape reinforcements for thin fragile wafer or glass panel.

Patent Coulomb-Force E-Chuck has the best characteristics than many electrostatic chucks under long-term advanced researches and developments. Patent Coulomb-Force E-Chuck is an ideal handling tool for soft and thin materials.

■ Operational Environment
(1) Atmospheric Pressure.
(2) Vacuum Environment.

■ Adsorbable Material
(1) Metal conductor (e.g., copper foil)
(2) Semiconductors (e.g., silicon, GaAs)
(3) Insulators (e.g., paper, glass panel)
(4) Porous objects.
(5) The adsorption force per unit area is related to the adsorption material and the contact surface smoothness.
(6) The material ranking of the adsorption force per unit area is : Metal 1st, Semiconductors 2nd, Insulator 3rd.

■ Features of Patent Coulomb-Force E-Chuck
(1) Coulomb-Force Electrostatic Chuck.
(2) Patent Coulomb-Force E-Chuck was developed a long time and has dozens of international patents.
(3) Stable and uniform adhesion force is achieved by applying the voltage to the electrode
(4) Apply the lowest voltage to keep maximum adhesion force.
(5) Because the voltage potential of the object backside is zero, adhesion will not affect the backside circuits.
(6) Be able to adhere various materials : metal / semiconductor / glass / paper / porous materials.
(7) Work normally in vacuum environments and general atmospheric environments.
(8) Cab define adhesion area and non-adhesion area. Non-adhesion area can define other functions.
(9) It can be made by different substrates. Such as stainless, aluminum, ceramic, semiconductor wafer or glass.
(10) It can be customized into various sizes and thicknesses for customer's applications.
(11) Advanced technology encloses the electrical field in the E-Chuck. E-Chuck becomes a move-free carrier.
(12) After adhesion setting, Move-Free Supporter can move freely even disconnecting the power supply. Move-Free support can support hardness or shape reinforcements for thin wafer or glass panel.
​Patent Coulomb-Force E-Chuck has been developed for a long time and has dozens of international patents.
