Based on application of heated bi‐metal strip bending theory to measured chip warp on 0.5 mm thick bare Corning ® EAGLEXG ® Glass and Corning Lotus™ NXT Glass, low substrate CTE minimizes chip warp. Different substrates have different effective process temperatures. Chip warp is relatively insensitive to substrate Young’s modulus vs. substrate CTE.
