  The semiconductor industry has high requirements for product quality and cleanliness of the production environment. Metal contamination is harmful to chips, so metal contamination on silicon wafers should be avoided. The purpose of this study is to exchange experience in solving the problem of metal contamination on the surface of silicon wafers, and to introduce how to use complementary measurement techniques to detect trace metal contamination on the wafer surface and find out the root cause of the problem, Explain the difficulty of selecting a suitable method from among multiple detection methods, and explore the dependence of lifetime measurement techniques on heat treatment. This article aims to address contamination on the surface of silicon substrates and three different examples of metal contamination will be discussed. The first is Ni diffusion, such a fast-diffusing species, which is a metal contamination that diffuses from a spot on the edge of the wafer. The...

  In recent years, microwave digestion technology has been widely used in food, medicine, textile, plastics, geology, metallurgy, coal, biomedicine, petrochemical, environmental monitoring, sewage treatment, cosmetics and many other industries have been widely promoted , f ollowing that, there are more and more product choices in the market, and the choice of imported and domestic microwave digestion vessel  makes many users have a dilemma.   The inner vessel  of the imported microwave digestion apparatus is indeed a bit tricky in terms of processing cycle and product price, and the safety of the domestic microwave digestion vessel  has not been tried, which is worrying.   Speaking of domestic microwave digestion vessel s, many users will worry about its safety. In fact, domestic microwave digestion vessel s have made great progress after development. Both performance and application methods can fully meet the needs of users in various industries, n ot as w...

About volumetric flask, our PFA flask belonds to A class, resistance to strong acid, alkali and various organic solvents, smooth inner wall, material stability much better, low blank value of metal elements, lead and uranium contents are less than 0.01ppb non-leachable, ensure the ultra clean background Volumetric flasks are highly transparent, easy to clean, and meet Class A tolerances. Flasks are molded PFA, which is highly resistant to heat and chemical contamination. PFA surface properties offer superior clean-up compared to glass and reduces risk of sample carryover in trace analysis applications. Screw cap design provides reduced contamination risk, compared to traditional stopper design.  Application: Suitable for storing and packing high concentration, high purity and strong corrosive drugs and chemical reagents and standard samples. Such as: the State Oceanic Administration for the storage of ocean seawater standard and mercury standard solution; Antarctic R...

Photovoltaic, semiconductor, solar energy and other industries, silicon wafer, wafer, glass, liquid crystal screen, battery wafer, as we know, these advanced material is expensive, when cleaning it, we must be careful and ensure the items container anti-corrosion, so that make sure the advanced materials in perfect condition during washing process. PFA wafer c assette, container  of wafer can be customized and designed by customers' request, able to resist strong acid, strong hydrofluoric acid, strong base and heat up to 200~220ºC, use to deliver wafers in acid & base process of Fabrication factory. One-piece molded PFA construction, designed to be used in containers with an opening of at least 3 inches in diameter.  Chemically inert and resistant to temperature extremes, they are an excellent choice for holding or immersing small parts or sample material in corrosive or solvent baths.  A convenient hook allows the dipper/sieve to be hung from the rim of the cont...

Teflon flasks usually have a round-bellied and narrow-necked appearance, which is significantly different from a beaker.  Its narrow mouth is used to prevent the solution from splashing or to reduce the evaporation of the solution, and can be used with rubber stoppers to connect other PFA equipment.  When the solution needs a long time to react or heat to reflux, a polytetrafluoroethylene flask is generally used as a container.  The opening of the flask does not have a protruding notch like a beaker, and it is easier to flow down the outer wall when the solution is poured, so usually a PTFE stirring rod is used to lightly touch the mouth of the bottle to prevent the solution from flowing down the outer wall.  Because the mouth of the flask is very narrow, it is not suitable for stirring with a tetrafluoroethylene stirring rod. If you need to stir, you can hold the mouth of the bottle and turn your wrist slightly to mix smoothly. If heating to reflux, put a magnetic s...
