Patent number: 7737001Abstract: In a stealth dicing process for a semiconductor device with a low dielectric constant layer, the occurrence of poor appearance such as a defective shape or discoloration in the layer is reduced or prevented as follows. A low dielectric constant layer is formed in an interlayer insulating layer formed on the main surface of a semiconductor wafer.
