Title: Method for removing etch residue resulting from a process for forming a via
Inventor: NGUYEN THIEN T
IPC: H01L21/02
Filed: 2001-11-06
Granted: 2003-03-11
Abstract: Etch residue, resulting from a process used in forming a via, is removed using a process that does not require using a liquid chemical solvent and does not result in excessive charge build-up in the via. One step is to use a fluorocarbon and oxygen. These gases are energized by both microwave and RF. Another step is to introduce argon, in addition to the other two gases, also energized by microwave and RF. This has the effect of removing any additional residue which tends to stick on the surface above the via as well completing the removal of etch residue in the via. An additional step is simply to apply de-ionized water to remove any remaining fluorinated residue that, as a result of the preceding two steps, is highly soluble in water.

Title: Spin-on anti-reflective coatings for photolithography
Inventor: BALDWIN TERESA
IPC: C09D5/00
Filed: 2001-12-20
Granted: 2004-01-11
Abstract: Anti-reflective coating materials for ultraviolet photolithography include at least one absorbing compounds and at least one pH tuning agent that are incorporated into spin-on materials. Suitable absorbing compounds are those that absorb around wavelengths such as 365 nm, 248 nm, 193 nm and 157 nm that maybe used in photolithography. Suitable pH tuning agents not only adjust the pH of the final spin-on composition, but also influence the chemical performance and characteristics, mechanical performance and structural makeup of the final spin-on composition that is part of the layered material, electronic component or semiconductor component, such that the final spin-on composition is more compatible with the resist material that is coupled to it. More specifically, the pH tuning agent strong influences the polymeric characteristics, the structural makeup and the spatial orientation that results in increasing the surface properties of the anti-reflective coating for optimal resist performance. In other words, a pH tuning agent that merely adjusts the pH of the spin-on material without influencing the mechanical properties and structural makeup of the spin-on composition or the coupled resist material is not contemplated herein. A method of making absorbing and pH tuned spin-on materials includes combining at least one organic absorbing compound and at least one pH tuning agent with at least one silane reactant during synthesis of the spin-on materials and compositions.
