Lumped Parameter Model for Silicon Crystal Growth

Monocrystalline silicon is an essential material for modern technologies today and in the near future. The continuous improvement of the manufacturing processes for monocrystalline silicon is, therefore, key to meet the demand for ever‐increasing device performance and reduced production costs.

Wafer, Si

A monocrystalline silicon seed crystal is brought into contact with one end of a polycrystalline silicon ingot. Starting from here, an RF coil melts a small region of the polysilicon which, after cooling down, forms monocrystalline silicon with the crystallographic orientation of the seed crystal (e. g. 100, 110 or 111).The RF coil and the melted zone move along the entire ingot.

Monocrystalline Silicon

As a result, the graphite heater to heat such a crucible and the heat shield member installed outside the heater to intercept heat from the heater have diameters as large as 1000–1300 mm. In connection with this, the upper parts exposed to Si vapor and SiO gas at high temperature tend to suffer from cracking and chipping as a result of the reaction between carbon and silicon.
