Used HITACHI / KOKUSAI DD-1223VN #9285063 for sale

HITACHI / KOKUSAI DD-1223VN is an advanced diffusion furnace and accessories designed for usage in semiconductor manufacturing and research environments. This diffusion furnace is capable of rapid thermal processing of various materials and substrates, allowing for high-precision control over the heating rate and temperature. The equipment is comprised of a power-rack module, a main controller unit, two independently-controlled crucibles, a heater block, and a precision temperature controller unit. The power rack module houses both the main power supply and the heater block, and is designed to maintain a steady voltage for precise diffusion heating. The main controller unit works as the ?brain? of the system, and allows users to control the temperature of both crucibles through an intuitive graphical interface. The two crucibles can be controlled independently, and are heated to a maximum temperature of 1150?C, with temperature ramp rates of up to 300?C/sec. The heater block is composed of multiple graphite blocks, each of which is attached to a thermocouple in order to achieve precise temperatures over the entire block surface. The heater block and crucibles are enclosed in a quartz chamber for additional safety and accuracy. The precision temperature controller unit monitors and maintains a constant temperature of 1?C or better for both crucibles during the diffusion process, and features a variety of automatic features to ensure precise heating. HITACHI DD-1223VN also includes various safety features. The graphite blocks are designed to prevent contact between the heating elements and sample substrates, and the quartz chamber is designed to prevent any spread of heat into the surrounding environment. Additionally, a nitrogen purge unit helps prevent oxidation, and a cooling and scrubbing machine helps reduce dust and exhaust from the process. In conclusion, KOKUSAI DD-1223VN is an advanced diffusion furnace and accessories designed to offer maximum precision and reliability in semiconductor manufacturing and research environments. Its power rack module, main controller unit, two independently-controlled crucibles, heater block, and precision temperature controller unit all work together to provide reliable diffusion processing. And its array of safety features ensure a safe, accurate, and efficient process.
