外露光刻胶的研制是光刻胶研制过程中关键的步骤，因此对研制过程及其参数(温度、研制时间等)的选择要特别注意。在喷淋显影过程中，对每个基板分别进行单独显影，并在暴露区域连续喷淋新显影剂或蚀刻剂，以防止显影剂饱和。

SAWATEC开发人员可用于水坑或喷雾开发，在此过程中，根据应用程序的技术和经济标准选择佳流程。与水坑开发相比，喷雾开发的优点是可以释放非常小的精细结构。水坑法的优点是，当衬底有较深的结构时，显着较少的显影液需要和较好的结果。

SMD系列用于清洗和显影8英寸(200mm)以下的晶圆或6英寸(150x150mm)以下的基板。过程——室工作Ø212毫米。

由SAWATEC公司开发的SMD具有良好的工艺性能、低的化学消耗和可靠的重复性，甚至具有较厚的光刻胶层。由于操作简便，易于清洗，这些仪器是理想的适合于实验室，研发，研究所和试点项目。

该仪器可作为台式或移动式机柜。
