A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

A method to improve vibration isolation in semiconductor process level inhibits vibration frequencies transmitted through building structure from production tools, pumps, compressors, chillers, AHUs (Air Handling Units), and footfalls traffic on raised floor system on to tool pedestals and pads from affecting semiconductor fabrication processes. Rapid advancement and technological evolution in semiconductor industry foresee the imminent requirements for decrease in semiconductor chip node sizes to single digit nanometer. Dealing with such advancements, the tool pedestal systems are also requiring tighter specifications for stiffness and vibration isolation/reduction. Some key tools used in the semiconductor fabrication process require improved barrier from electromagnetic interference (EMI), as the disturbance from EMI degrade the performance of semiconductor processing tools that are key to the fabrication process and production yield rate.
