15555 results about "Chemical formula" patented technology

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.

Method for forming a wiring of a semiconductor device, method for forming a metal layer of a semiconductor device and apparatus for performing the same

In a method for forming a wiring of a semiconductor device using an atomic layer deposition, an insulating interlayer is formed on a substrate. Tantalum amine derivatives represented by a chemical formula Ta(NR1)(NR2R3)3 in which R1, R2 and R3 represent H or C1-C6 alkyl group are introduced onto the insulating interlayer. A portion of the tantalum amine derivatives is chemisorbed on the insulating interlayer. The rest of tantalum amine derivatives non-chemisorbed on the insulating interlayer is removed from the insulating interlayer. A reacting gas is introduced onto the insulating interlayer. A ligand in the tantalum amine derivatives chemisorbed on the insulating interlayer is removed from the tantalum amine derivatives by a chemical reaction between the reacting gas and the ligand to form a solid material including tantalum nitride. The solid material is accumulated on the insulating interlayer through repeating the above processes to form a wiring.
