Semiconductor Chip Manufacturing: Related to Cancer, Birth Defects and Miscarriages The process of semiconductor chip fabrication in clean rooms involves exposure to photoresist containing glycol ethers and other dangerous solvents. There have been several cases litigated against National Semiconductor, IBM and Zilog based on exposure to ethylene based glycol ethers. Workers May be Exposed during the Semiconductor Chip Manufacturing Process. Manufacturing a computer chip involves a complex fabrication process, creating a chip that consists of many layers with each layer having a complex pattern. The step in the manufacturing process that results in exposure to solvents is the creation of the detailed pattern on the silicone layers. The detailed patterns are created on the layers of silicon using a technique called photolithography. Photolithography involves applying photoresist over the silicon. The unexposed silicone is washed away using solvents. Often the the solvent contains harmful substances such as glycol ethers, and plant clean room workers involved in photolithography may be harmed by inhalation and exposure.
