Webshows the relation between spin speed and resist thickness for 4-inch substrates. 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

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.
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 … WebAug 15, 2008 · Similarly, an inaccurate application of the resist with pipettes or a dispenser (low pressure caused by pulling too fast) may lead to bubbles and thus cause inhomogeneity of the resist film. Air bubbles can be avoided if the resist is adjusted to the temperature of the work place before the coating step, if the bottle is opened a bit to ...
