Alternative resist adhesion and electroplating layers for LIGA process

 The fabrication of high aspect ratio microstructures using the X-ray lithography and electroplating step of the LIGA process requires, that the metal layer on the substrate (plating base) enables a flawless resist adhesion and provides a high conductivity for the following electroplating process. In addition, a flawless metal adhesion after electroplating has to be ensured. Typically metal layers of titanium, but also of copper and gold are used. In case of higher structures, fluorescence radiation generated in the metal layer during exposure reduces the bond strength between the resist and the adhesion layer [7]. Since the fluorescence probability decreases with a decreasing atomic number, the suitability of conductive carbon as the plating base was investigated and compared to results achieved with titanium. The resist adhesion was increased tremendously on the carbon layer but the metal adhesion is insufficient. Therefore, platinum islands were deposited on the conductive carbon to facilitate good metal adhesion. The resulting resist adhesion was still superior compared to titanium. In addition, metal adhesion was achieved on these layers.

Re-engineering of the design process for concurrent engineering

According to the requirements of concurrent engineering, three interdependency relationships (uncoupled relationship, coupled relationship and decoupled relationship) between design activities are presented in this paper. And the coupled relationship plays an important role in concurrent product design process. To represent the precedence relationships among design activities, a directed graph is used to describe the design process. And the interdependency relationship between activities is illustrated by a Design Structure Matrix which is the transpose of the accessibility matrix of the corresponding graph. Using the DSM, an algorithm of recognizing the coupled activities during the design process is presented. Moreover, an algorithm to figure out the order levels of activities during the design process is proposed. And both algorithms are illustrated with a die design example.
