To form spacers with a high aspect ratio on an anode plate for field emission displays (FEDs), glass to glass anodic bonding was used. A rib-type soda lime glass, width 100 µm×height 1000 µm×length 75 mm, was used as a spacer and bonded on a 3.54 in mono green color anode plate patterned with Al/Cr film as an interlayer by anodic bonding. To bond the spacers on the anode plate vertically, two types of spacer holders were fabricated and tried with photoetchable glass and an n-type (110) Si wafer. The spacer process was used to fabricate an evacuated FED panel.
