摘要:
An isotopically-enriched, boron-containing compound comprising two or more boron atoms and at least one fluorine atom, wherein at least one of the boron atoms contains a desired isotope of boron in a concentration or ratio greater than a natural abundance concentration or ratio thereof. The compound may have a chemical formula of B2F4. Synthesis methods for such compounds, and ion implantation methods using such compounds, are described, as well as storage and dispensing vessels in which the isotopically-enriched, boron-containing compound is advantageously contained for subsequent dispensing use.
摘要:
A method of implanting carbon ions into a target substrate, including: ionizing a carbon containing dopant material to produce a plasma having ions; optionally co-flowing an additional gas or series of gases with the carbon-containing dopant material; and implanting the ions into the target substrate. The carbon-containing dopant material is of the formula CwFxOyHz wherein if w=1, then x>0 and y and z can take any value, and wherein if w>1 then x or y is >0, and z can take any value. Such method significantly improves the efficiency of an ion implanter tool, in relation to the use of carbon source gases such as carbon monoxide or carbon dioxide.
摘要:
An ion implantation system and process, in which the performance and lifetime of the ion source of the ion implantation system are enhanced, by utilizing isotopically enriched dopant materials, or by utilizing dopant materials with supplemental gas(es) effective to provide such enhancement.
摘要:
A first method for producing a doped region in a semiconductor substrate includes performing a first implant step in which a carborane cluster molecule is implanted into a semiconductor substrate to form a doped region. A second method for producing a semiconductor device having a shallow junction region includes providing a first gas and a second gas in a container. The first gas includes a first dopant and the second gas includes a second dopant. The second method also includes implanting the first and second dopants into a semiconductor substrate using an ion. The ion source is not turned off between the steps of implanting the first dopant and implanting the second dopant.
