WebIn this paper, we address the problems of (i) edge bead formation when using thick resist on small samples, (ii) sample damage during lithography mask touchdown, (iii) resist reticulation during prolonged argon-based inductively coupled plasma reactive ion etching (ICP-RIE), and (iv) redeposited material on the feature sidewalls. WebDETAILED DESCRIPTION. The edge bead removal (EBR) measurement method of the present invention is a method for finding the distance from the edge of a semiconductor wafer to a location where photoresist was removed about the circumference of the wafer. This location is also known as an EBR line.
WebSep 12, 2024 · An edge bead removal measurement method includes determining an edge (101) of a wafer about a circumference of the wafer. A location of a wafer notch (104) on the edge of the wafer is determined. A location of a center (102) of the wafer is determined. A distance (112) from the edge of the wafer to an edge bead removal line about the …
