CZ Growing Equipment

Producing the highest quality silicon ingots at some of the industry’s fastest speeds, lowest costs and largest formats.

Our family of Czochralski (CZ) furnaces is designed to produce the highest quality silicon ingots at some of the industry’s fastest speeds, lowest costs and largest formats. We customize every product for every customer, whether it’s the modification of one part, or a complete, state-of-the-art crystal growing system tailored precisely to your needs.

LCT is a leader in CZ growing equipment for ingots used in machined silicon parts, optics, sputtering targets, etch electrodes and more. Over the years, our CZ furnaces have created ingots that provide electrical power for satellites, heat-resistant mirrors for our national defense systems and the machined parts that produce next-generation integrated circuits and solar cells.

Key features of our product line.
Use the Czochralski (CZ) method, which allows for growth of single, large crystals at lower cots than other growth methods.
Modularity—designed to be easily and inexpensively refitted for multiple hotzone sizes. As industry standards—and your needs—change, your furnace system can, too.
Faster crystal growth—Our systems are achieving some of the fastest crystal growth speeds in the industry, to speeds of 1.6 - 2.0 mm per minute.
Hotzone sizes range from 24 to 36 inches optimized for 200mm, 250mm and 300mm wafers (custom - capable of accommodating other sizes).
Low operating costs—Much of our research and development targets lowering your operating costs, such as:
  • Low-power, high-efficiency hotzones that reduce power consumption by nearly half, extend the lifetime of crucibles to approximately 250 hours vs. typical 185 to 195 hours
  • Newly-designed heaters and insulation boost efficiency and lower operating costs
  • Superconducting magnets vastly reduce power requirements vs. resistive magnets
Automation—currently available automated capabilities include:
  • KrystalVisionTM system for monitoring diameter and controlling melt level
  • Kayex Intelligent Crystal Control System (KICCSTM) for hardware and software process control
  • Web Integrated Grower Supervisor (WINGS) for remote furnace management and data collection
  • Self-cleaning filters that partially automate the cleaning process required after each growing session
