る。In this embodiment, a case will be described in which a gold M breast formed on a bonding butt is formed by a lift-off method. First, in FIG. 2(A), 21 is a half board & board, 22 is a layer 810 formed on the semiconductor substrate 11 mentioned above. Other than the part 13 (form the Z resist 14. Next, the above-mentioned 810.IQ2.2 and the strong adhesive resist I'r I
IF115 is deposited at a rate of, for example, 500 to 800/f, and then kl@16 is deposited, for example, at a rate of about 1 μm, in order to prevent the oxidation of Ti1l during the process (2). As shown in -, by peeling off the resist 14, simultaneously (2) remove the 'I'I layer xs7J and Alrf41e deposited on the resist 14,

易となる。As described in detail above, according to invention C2, a metal breast with strong adhesion to the Si01 layer of the f base is formed at the most FM of the bonding pad portion, so that the strength margin for redoing bonding etc. is increased. Furthermore, the strength required for the bonding pad can be increased by having the metal layer formed at the bonding pad part bear the strength, while the metal film for forming the metal wiring can be made considerably thinner. This makes it possible to easily form fine patterns.
