Abstract

A type of partially prefabricated waffle slabs, for use in building wafer foundry (or other structures) and for the purpose of installing equipment for wafer production. Said partially prefabricated waffle slabs comprise primarily: a main body, having a number of primary holes for air circulation or other mechanical needs. Said main body can have pillar (or column) holes or notched comers for the penetration of major pillars (or columns). Said partially prefabricated waffle slabs have the advantage of meeting the requirements of achieving field safety, reasonable cost, rapid production, transportation needs, easy installation, and simple structural joints and at the same time complying with the specifications of Fab.
