Electrostatic carrier tray
View Patent ↗An electrostatic carrier tray is an apparatus that is used to temporarily grasp and to transport semiconductive coupons/wafers. The apparatus mainly includes a primary substrate, a plurality of electrostatics field generating circuits, a conformal coating, a structural backing, and a power-delivery and control system. The electrostatics field generating circuits are positioned on one side of the primary substrate, and the power delivery and control system is positioned on the other side of the primary substrate. The electrostatics field generating circuits are used to bond the semiconductive coupons/wafers to the apparatus. The structural backing is used to handle the apparatus while transporting the semiconductive coupons/wafers and is also used to protect the power-delivery and control system from physical damage. The conformal coating is superimposed onto the electrostatics field generating circuits and the primary substrate as a means of protection.
