Contamination is the sole reason a clean roomis necessary for wafer processing. Environmental debris like dust and hair, among others, directly impact the wafer’s performance. The products already go through a thorough polishing process immediately after growth. However, they can still accumulate particles.

Customer ServiceIn semiconductor manufacturing, the efficacy of the silicon wafer cleaning process is paramount. Contaminants, even at a microscopic scale, can drastically impede semiconductor device performance. Particles can lead to physical defects, and metallic impurities can alter electrical properties, contributing to lower yields and reliability.
As with the production of silicon chips, production of c-Si wafers begins with the mining of silica, found in the environment as sand or quartz. Silica is refined at high temperatures to remove the oxygen and produce metallurgical grade silicon, which is approximately 99.6% pure. However, silicon for semiconductor use must be much purer.
Editor’s Note: This article was originally published in April 2016 and has been updated with new information and re-posted in February 2024. In the intricate world of semiconductor manufacturing, the cleanliness of silicon wafers is not just a requirement; it’s a critical success factor.
But it has been suggested that, despite the use of respiratory masks, workers remain overexposed to silicon dust. The use of silane gas is the most significant hazard in the production of c-Si because it is extremely explosive and presents a potential danger to workers and communities.
The increased concentration of finely dispersed man-made silicon production waste confirms the need to take organizational and technical measures to reduce the dust load, including the creation of economic conditions for pelletizing the batch. Content may be subject to copyright.
Sawing c-Si wafers creates a significant amount of waste silicon dust called kerf, and up to 50% of the material is lost in air and water used to rinse wafers. This process may generate silicon particulate matter that will pose inhalation problems for production workers and those who clean and maintain equipment.
