The Significance of Wafer Cleaning and Reclaim to the Semiconductor Industry

The Significance of Wafer Cleaning and Reclaim to the Semiconductor Industry

There are two vital wet processes that play a significant role in Wafer Automation - they are named wafer cleaning and reclaim. These industry procedures are popular for they generate a huge benefit chiefly to the semiconductor industry.

Wafer cleaning - in a Nutshell Wafer cleaning just like Wafer Mapping has long been acknowledged as a significant industry procedure. It consists of the removal of particulate and chemical contaminations from the semiconductor surface without generating any harm to the substrate. This process is made mainly for silicon-related material as this is the most mutual and significant element operated for the fabrication of integrated circuits (ICs). Wafer cleaning process usually is powered on wet-chemical processes where hydrogen peroxide solutions are exercised.

Some gains and benefits of wafer cleaning:      

Provides effective elimination of all types of surface contaminants, organic and metallic problems Comparatively safe, the course is simple, and reasonable for the production application Implementable by a diversity of techniques Offers no etch or harm to silicon Improves the performance of the semiconductor articles Environment-friendly since it practices contamination-free and volatilizable chemicals.

What is Wafer Reclaim?

In simple terms, wafer reclaim comprises the process of altering used Wafer Automation to its brand new appearance at a lower cost. This is definitely a cost-effective alternative to purchasing new wafers. This process comprises a number of steps, which encompass: (1) sort the process that is critical to averting metallic contamination (2) strip - this is achieved through wet immersion using batch tanks; (3) Lapping and grinding - needed for thick SOI (4) polish using chemical and mechanical polishing, which can eliminate residual slurry and unwelcome particles from the substrate, and metallic contaminants; (5) cleaning - which is achieved in batch immersion tanks and (6) Inspection - the step that sorts again the thickness and flaw level before being returned for use in the fab.

Some assistance of wafer reclaims   

Meaningfully cuts production costs of manufacturing brand new wafers.

Serves environmental profits; waste materials from the production of new wafers are essentially decreased by this alternative.

It aids extend the life of wafers - a longer span of time for implementation

Again, wafer cleaning and wafer reclaim give a huge benefit to the semiconductor industry precisely when it comes to cutting the production costs while the product usability is not bargained. Consequently, it just makes sense to make use of these technologies.
