WebAug 1, 2002 · The “Ion-Cut”, a layer splitting process by hydrogen ion implantation and subsequent annealing is a versatile and efficient technique of transferring thin silicon … WebJun 4, 1998 · We have studied the process of buried oxide formation as a function of implantation and annealing conditions. Concentrating on substoichiometric implants (<1×10 18 O/cm 2 ), we varied the implantation energies from 100 keV to 1 MeV. Some apparent precipitation of SiO 2 similar to that observed in Czochralski‐grown silicon occurs on … One prominent method for preparing silicon on insulator (SOI) substrates from conventional silicon substrates is the SIMOX (separation by implantation of oxygen) process, wherein a buried high dose oxygen implant is converted to silicon oxide by a high temperature annealing process. See more Ion implantation is a low-temperature process by which ions of one element are accelerated into a solid target, thereby changing the physical, chemical, or electrical properties of the target. Ion implantation is used in See more Doping Semiconductor doping with boron, phosphorus, or arsenic is a common application of ion implantation. When implanted in a semiconductor, each dopant atom can create a charge carrier in the semiconductor … See more Ion beam mixing Ion implantation can be used to achieve ion beam mixing, i.e. mixing up atoms of different elements at an interface. This may be useful for achieving graded interfaces or strengthening adhesion between layers of … See more Hazardous materials In fabricating wafers, toxic materials such as arsine and phosphine are often used in the ion implanter … See more Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, … See more Tool steel toughening Nitrogen or other ions can be implanted into a tool steel target (drill bits, for example). The structural change caused by the implantation produces a surface compression in the steel, which prevents crack propagation … See more Crystallographic damage Each individual ion produces many point defects in the target crystal on impact such as vacancies and interstitials. Vacancies are crystal lattice … See more kosma heating in sheridan wyoming
