Wet chemical texturing equipment
Product function
1.Removing the damaged layer and surface dirt during wiresawing
2.Using strong alkali to etch the crystalline silicon surface to form a regular pyramidal suede, Increasing the absorption of sunlight and reduce the reflectivity of the silicon wafer
3.Increasing the surface area of the silicon wafer, then the PN junction area also increases accordingly

Automatic silicon cleaner
Product function
Main functions: With HF+HNO3 mixed acid corrosion cleaning and reagent (weak acid) soaking, cleaning function
Fully automatic wafer degummer&singulator&cleaner
Equipped with absorbent plate, cassette positioning, slow lifting, drying tank and other patented technology, which can separate wafers efficiently and reduce the broken rate
Japanese Keentu bus communication system and absolute bus servo are adopted, whcih can quickly grasp the processing of production data and achieve intelligent monitoring,which is compatible with various specifications of silicon chip sizes and switching time between different sizes does not exceed 4 hours
Fully automatic wafer degummer&singulator&cleaner
Whole cutter feeding,continuous wafer loading and inserting to improve the production capacity. In addition, through the improvement of the mechanism, the basket changing time is minimized, so that the production capacity of the whole machine is released to the best
Wafer degumming, inserting and cleaing integrated and are automatic, whcih can reduce the turnover link; loading fully automatic, one operator can handle several machines, which can save manpower
