Used HITACHI / KOKUSAI DD-1223V #9358304 for sale

HITACHI / KOKUSAI DD-1223V is a diffusion furnace and accessories. It is a high-temperature furnace capable of temperatures up to 1250°C that is typically used for diffusion processes and semiconductor device fabrication. It is an ideal choice for precise and uniform temperature control, allowing users to perform process steps with precise accuracy. The furnace is a vertical, box-type furnace, with a top-mounted lid that provides excellent temperature uniformity. Inside, a stainless steel housing houses the recirculated quartz tube for precise temperature control. The tube is mated to a quartz susceptor into which the substrates are loaded. The tube is equipped with a protective O-ring that allows for sealing and tight temperature control of the furnace atmosphere. The furnace also features an Inconel reaction chamber and is mounted on a oil bath, which serves as the heat source. HITACHI DD-1223V is equipped with a direct-drive quartz crucible for the diffusion process, with a maximum load capacity of 200g. It can also handle drive motors up to 2.5kW and has an overall operating temperature range of 500°C to 1250°C. The furnace is also fitted with a digital temperature controller, a PID closed-loop temperature control equipment, an air purging system and an emergency stop switch. The controller allows precise set points to be programmed and has the ability to monitor, record and store all process parameters during each step. It also allows the adjustments of the temperature, purity, pressure and the rate of heating and cooling of the furnace, giving users greater control over the process. The air purging unit ensures uniform temperature distribution throughout the furnace and helps to maintain a clean, free from contamination diffusion environment. KOKUSAI DD-1223V is a reliable and precise diffusion furnace machine ideal for semiconductor device fabrication and other temperature-sensitive processes. It offers precise temperature control, uniform temperature distribution, and an easy-to-use user interface. This combination of features makes DD-1223V the ideal tool for a wide range of applications.
