Find the Use of Plasma Systems for Ultra-Fine Cleaning and Etching at PVA TePla with Better Prices One of the world’s leading system engineering companies- PVA TePla’s core values is in the fields of systems for hard-metal sintering and crystal growing as well as the use of plasma systems for surface activation, functionalization, coating, ultra-fine cleaning, and etching. Acoustic Microscopy is a practice that represents the progressions and achievements of science and equipment. It lets for the growth of research creates opportunities for discovery, permits deeper exploration of a specimen and enables scientists to enhance assess and observe micro-environments. At PVA Tepla AG, a varied set of connections of sales and service centers supports you with high-end technologies in the ultrasonic inspection of samples and with individual order analyze. Top trained specialists advise you, among other things, on useful equipment and special developments and provide you with meaningful analysis reports. By enhancing their ability to study a sample, scientists can obtain more accurate data, prove or disprove a theory, gain an understanding of the unseen world around us and pursue new cures, treatments or products to make everyday life safer and healthier.
Scanning acoustic microscopy: It works by expressing alert echo from a transducer at a small point on a target object. Sound hitting the object is scattered, absorbed, reflected or transmitted. It is possible to detect the scattered pulses travelling in a particular direction. The `time of flight' of the pulse is defined as the time taken for it to be emitted by an acoustic source, scattered by an object and received by the detector, which is usually coincident with the source. The time of flight can be used to determine the distance of the inhomogeneity from the source given knowledge of the speed through the medium. Founded on the size, a value is assigned to the location examined. This process of Scanning acoustic microscopy is repeated in a systematic pattern until the entire region of interest has been investigated. Often the values for each point are assembled into an image of the object. The contrast seen in the
image is based either on the object's geometry or material composition. The resolution of the image is limited either by the physical scanning resolution or the width of the sound beam.
As well, our PVA TePla Analytical Systems designs and manufactures high-tech wafer cleaning equipment. Our etch process removes organic material from silicon wafers fast. Semiconductor manufacturing involves the repeated etching and cleaning of the silicon wafers and the Piranha mixture is a favorite method for the resist strip of wafers to prepare them for further processing.
Also, we offer the best Plasma Ashing service with better prices that is the process of removing the light-sensitive coating from an etched wafer. Using a plasma source, a monatomic substance known as a reactive species is generated. Oxygen or fluorine is the most common reactive species. The reactive species combines with the photoresist forming ash which is removed with a vacuum pump.
