Defect Engineering During Czochralski Crystal Growth and Silicon Wafer Manufacturing
Single crystal silicon has played the fundamental role in electronic industry since the second half of the 20th century and still remains the most widely used material. Electronic devices and integrated circuits are fabricated on single-crystal silicon wafers which are produced from silicon crystals grown primarily by the Czochralski (CZ) technique. Various defects are formed in the growing cry...
متن کاملIn situ observation of antisite defect formation during crystal growth.
In situ x-ray diffraction (XRD) coupled with molecular dynamics (MD) simulations have been used to quantify antisite defect trapping during crystallization. Rietveld refinement of the XRD data revealed a marked lattice distortion which involves an a axis expansion and a c axis contraction of the stable C11b phase. The observed lattice response is proportional in magnitude to the growth rate, su...
متن کامل4. Generation and Propagation of Defects During Crystal Growth
This chapter presents a review of the typical growth defects of crystals fully grown on (planar) habit faces, i. e. of crystals grown in all kinds of solutions, in supercooled melt (mainly lowmelting organics) and in the vapour phase. To a smaller extent also growth on rounded faces from the melt is considered when it seemed to be adequate to bring out analogies or discuss results in a more gen...
متن کاملEFFECT OF SPIRAL DESIGN ON CRYSTAL ORIENTATION DURING SINGLE CRYSTAL GROWTH
Geometrical design of the spiral crystal selector can affect crystal orientation in the final single crystal structure. To achieve a better understanding of conditions associated with the onset of crystal orientation in a spiral crystal selector, temperature field was investigated using three-dimensional finite element method during the process. Different geometries of spiral crystal selec...
متن کاملThermodielectric generation of defect modes in a photonic liquid crystal.
Photonic defect modes induced by in situ formation of an ill-defined defect layer is demonstrated in a cholesteric liquid crystal (CLC). The local deformation of the one-dimensionally periodic helical structure is achieved by means of the thermodielectric effect, which alters the pitch in the middle of the cholesteric structure. The defect-mode peak in the photonic band gap appears in the trans...
