Patent ID: 8736051

Claim:
A semiconductor device comprising: an interlayer insulating film containing Si, O, C, and H; an under-bump metal film containing Ni disposed over the interlayer insulating film; and a bump electrode disposed over the under-bump metal film, wherein in the interlayer insulating film, a ratio of a peak height of Si—CH 3 near a wave number 1270 cm −1 to a peak height of Si—O near a wave number 1030 cm −1 is 0.15 or greater and 0.27 or less, and a ratio of a peak height of Si—CH 2 —Si near a wave number 1360 cm −1 to a peak height of Si—CH 3 near the wave number 1270 cm −1 is 0.031 or greater, the ratios being obtained by Fourier transform infrared spectroscopy (FTIR).
