Abstract: The existing methodology for Front Opening Unified Pod (FOUP) cleaning, storage, and transfer is inherently flawed in three areas: a) equipment layout, b) intra-process wait time, and c) human handling. In each area, improved solutions are suggested and a new approach is developed and named In-line FOUP Cleaner (IFC). IFC is a new, singular approach accomplished via total integration of multiple equipment types including sorter, FOUP cleaner, stocker, particle counter, and the FDC monitoring system. Utilizing the IFC approach, significant improvements have been documented with respect to all three areas of concern. Overall cost savings, as well as a side benefit of improved fume removal, are carefully observed. It appears to be an interesting approach to solving the problems associated with FOUP cleaning, storage, and transfer for the next generation semiconductor fab.

Abstract: In order to be used as food supplements, materials (medicinal and aromatic plants, other materials containing active principles, etc.) need to be chopped and sorted by size, depending on the field of use: herbal tea, suspensions, tinctures, etc. The paper presents the results of research on the sorting process of some materials containing active principles (yarrow, alfalfa and willow bark) using a sorting machine provided with 2 electro vibrators fitted on each side of the framework within which 3 sieves with a mesh size of: 2.15, 4 and 8 mm are fitted, changing the oscillation regime of the sieves by adjusting the angle of the electro vibrators, in order to identify the optimal sorting regime.
