What is Wafer Contamination?
Cleanliness is next to godliness when it comes to making computer chips. Even little bits of dirt can create big problems and make the chips not work right. One of the frequent trouble makers are graphite carriers. They're used for transporting wafers during the manufacturing process. These carriers can sometimes shed small bits of matter, dirtying wafers and damaging their quality.
How Can CVD TaC Coating Assist?
To solve this, the researchers at Semixlab have developed a unique process known as CVD Coating. This approach involves coating the graphite carriers with a thin layer of a material known as tantalum carbide. They do this with a process called Chemical Vapor Deposition (CVD). The coating prevents particles from falling off and mucking up the wafers.
How Does the Coating Work?
How the CVD TaC Coating is Made The process of creating the CVD TaC coating is noteworthy. First a gas containing tantalum and carbon is placed in a hot chamber. Within this chamber, the gas undergoes a chemical reaction. This reaction forms a film of tantalum carbide on the graphite carriers. This coating is quite tough and durable, and provides long lasting protection to the wafers.
Big Strides in CVD TaC Coating
Semixlab has managed to significantly dampen wafer pollution (- 90%) with the CVD TaC cover. By preventing the graphite carriers from shedding particles, the technology helps create improved computer chips. With them, manufacturers have been able to manufacture chips with fewer defects, and that saves time and money in the production of the chips.
What is the Significance of CVD TaC Coating?
In summary, CVD TaC coating plays an important role in the fabrication of computer chips. It protects graphite carriers against particle loss to keep a clean manufacturing environment. With Semixlab’s offering, companies can produce better and more reliable computer chips, translating to greater quality and performance.
