In comparison to straightforward quartz rings, OP Quartz Rings provide better opacity, much better thermal shielding, and decrease light-weight transmission, assisting to keep up secure furnace problems and minimize wafer contamination.
Known for its Outstanding thermal stability, low thermal enlargement, and superb chemical resistance, this ring withstands severe processing environments and repeated thermal cycling.
The Remarkable thermal uniformity of Semixlab’s precision-polished quartz makes certain regular film thickness and superior area good quality throughout the wafer. The fabric’s optical transparency and infrared reflectivity can be tailor-made to improve heating effectiveness and reduce temperature gradients throughout the deposition zone.
・In comparison to silica wool and silica insulation, this product has large thermal resistance, fantastic sealing attributes and does not react with the quartz tube.
・Considering that alumina fiber is utilized, it characteristics lengthier provider life than silica fiber enabling reduction of insulation substitute frequency and wastes produced.
Acts like a protecting part to circumvent numerous contaminations during the etching manufacturing approach, ensuring sealing and defense of your chamber. It is applied in wafer manufacturing etching processes, which can be very low-temperature procedures.
In chemical vapor deposition (CVD) devices—which include LPCVD, PECVD, and substantial-temperature SiC or Si epitaxy reactors—the quartz ring serves being a structural and practical interface concerning the susceptor plus the reaction chamber. Its Most important purpose will be to isolate reactive gasoline flows, lower parasitic deposition on chamber partitions, and stabilize the thermal profile around the wafer.
In plasma etching (Dry Etch) procedures, the quartz ring acts to be a protective barrier in opposition to plasma erosion and ion bombardment, shielding the chamber’s metallic surfaces from contamination quartz insulation ring for semiconductor furnace and particle generation.
Robust chemical steadiness: Proof against most acids and corrosive substances besides hydrofluoric acid.
two µm). This mixture of purity and precision minimizes particle generation and supports constant procedure repeatability across high-quantity semiconductor generation traces. We anticipate your more inquiry.
※The lower impurity sort makes use of reduced impurity supplies in the outer products, interior filler and sewing thread. ・Thermal insulating rings have thermal resistance of 1200℃.
Selecting concerning OP and common quartz rings depends upon course quartz insulation ring for semiconductor furnace of action needs, furnace structure, and the need for thermal uniformity and wafer defense.
