Tips on Buying Silicon Wafer Cleaning Equipment
The wafer-cleaning equipment market has grown in recent years. Wafer cleaning is the exclusion of particles or impurities from the semiconductor surface without varying the quality of the surface. The performance of the device and its consistency are significantly affected due to the presence of contaminants and particulate impurities on the wafers of the device’s surface. For all manufacturing involving semiconductors and micro-electrical mechanical systems, one of the most important requirements is to maintain a precise cleaning process for silicon. This reduces yield problems that occur from both organic and inorganic residues. As the size of semiconductors continues to decrease, there are higher risks associated with the contamination of wafers, especially by particle contaminators. For increased efficiency in your manufacturing processes, you will need to purchase high-quality and reliable silicon wafer cleaning equipment for your manufacturing facility. There are a good deal of silicone cleaning equipment manufacturers on the market. With so many options available in the industry, selecting the best supplier can be hard and overwhelming. You need to do good research to ensure you find a wafer-silicone cleaning equipment manufacturer with a good reputation. When buying water-silicone cleaning equipment, there are important things to keep in mind to help you make the right choice. Here are some factors to consider when shopping for silicon wafer cleaning equipment:
Experience and the expertise of the manufacturing company: Silicon wafer cleaners are different from other products you will buy on the market and fit into a manufacturing environment. When you are purchasing this equipment, you will need to look for a company that has a proven track record with in-house expertise and support. You also need to confirm that the equipment they provide will meet all of your manufacturing requirements. Upcoming companies with little experience are likely to sell you substandard products or products that are not fully qualified to meet your requirements. Companies that have been in the field for a long time will offer various equipment options based on their experience working with various customers.
Technology: Buy equipment manufactured using the latest technology. As the quality and geometry of the semiconductors advance, the technology used to make wafer cleaners has also advanced. Finer geometries require finely washed and cleaned silicon, unlike in previous years, which involved just simple immersions in hot alkaline. Modern cleaning equipment uses megasonic cleaning, centrifugal spraying, and ultrasonic cleaning technologies. The enclosed systems effectively clean all particles and contaminant films. You’re better off buying from a company that implements such advanced technology.
Choose a manufacturing company that offers technical support and onsite repair. Many companies will sell you a product, but will not always offer good technical support or onsite repair if there is a problem. If a manufacturer does not offer good technical support or if the system does not work reliably, your manufacturing yields will be compromised. It is advisable to buy from a company that will offer technical support and repair of their wafer cleaning equipment in the event of a breakdown or malfunction.
To sum up, with these factors in mind, you will buy wafer cleaning equipment that is efficient and durable.
