Cracking photoresist
Webresist development grows imperative. Most of the earlier simulations of photoresist development do not adequately describe surface roughness because they considered the pho-toresist a uniform structure.

Figure 4. shows the relationship between spin speed and resist thickness for 8-inch (200 mm) substrates applying MEGAPOSIT SPR220-7.0 photoresist. Based on this curve a 375 RPM spin will yield a film thickness of approximately 30 μm. Nominal film thickness
WebDuring plating, flaking or a loss of adhesion can occur. After plating is complete, common problems include hydrogen cracking, dull and hazy deposits in the plating, blistering and oxidation. In this article, we will … Webmask. Hereby, the resist sidewalls show a more or less pronounced undercut which makes the lift-off easier to realize. However, image reversal resists generally do not cross-link. Hence, from approx. 120-130°C on, the resist structures start to soften, and the features rounden making them less suited for lift-off.
