摘要:
A method of removing a high molecular weight organic-comprising hard mask or BARC from a surface of a porous low k dielectric material, where a change in the dielectric constant of the low k dielectric material is less than about 5% after application of the method. The method comprises exposing the organic-comprising hard mask or BARC to nitric acid vapor which contains at least 68% by mass HNO3.

摘要:
A method of removing a water-comprising rinse/cleaning material from the surface of a device which includes high aspect ratio features (an aspect ratio of 5 or greater) where sidewalls of the feature are separated by 50 nm or less without causing stiction between the feature sidewall surfaces. The method relies on the use of a low surface tension drying liquid which also exhibits a high evaporation rate. The method also relies on a technique by which the drying liquid is applied. Increasing the evaporation rate of the drying liquid and application of the drying liquid in the form of a vapor helps to eliminate stiction.
摘要:
Cleaning solutions and cleaning methods targeted to particular substrates and structures in semiconductor fabrication are described. A method of cleaning fragile structures having a dimension less than 0.15 um with a cleaning solution formed of a solvent having a surface tension less than water while applying acoustic energy to the substrate on which the structures are formed is described. Also, a method of cleaning copper with several different cleaning solutions, and in particular an aqueous sulfuric acid and HF cleaning solution, is described. Also, methods of cleaning both sides of a substrate at the same time with different cleaning solutions applied to the top and the bottom are described.

Methods for preparing a substrate for a subsequent film formation process are described. Methods for preparing a substrate for a subsequent film formation process, without immersion in an aqueous solution, are also described. A process is described that includes disposing a substrate into a process chamber, the substrate having a thermal oxide surface with substantially no reactive surface terminations. The thermal oxide surface is exposed to a partial pressure of water above the saturated vapor pressure at a temperature of the substrate to convert the dense thermal oxide with substantially no reactive surface terminations to a surface with hydroxyl surface terminations. This can occur in the presence of a Lewis base such as ammonia.
摘要:
A H2O vapor based dry plasma process for pre-treating and strip-cleaning a reticle, a three layer gas distribution plate (GDP) assembly to control the heat load to the reticle during the plasma process, and a modified hole pattern for the GDP that further enhances stripping of resist from the edges of the reticle are disclosed.
摘要:
Embodiments disclosed herein generally relate to a process of depositing a transparent conductive oxide layer over a substrate. The transparent oxide layer is sometimes deposited onto a substrate for later use in a solar cell device. The transparent conductive oxide layer may be deposited by a “cold” sputtering process. In other words, during the sputtering process, a plasma is ignited in the processing chamber which naturally heats the substrate. No additional heat is provided to the substrate during deposition such as from the susceptor. After the transparent conductive oxide layer is deposited, the substrate may be annealed and etched, in either order, to texture the transparent conductive oxide layer. In order to tailor the shape of the texturing, different wet etch chemistries may be utilized. The different etch chemistries may be used to shape the surface of the transparent conductive oxide and the etch rate.

A method of removing resist material from a substrate having a magnetically active surface is provided. The substrate is disposed in a processing chamber and exposed to a fluorine-containing plasma formed from a gas mixture having a reagent, an oxidizing agent, and a reducing agent. A cleaning agent may also be included. The substrate may be cooled by back-side cooling or by a cooling process wherein a cooling medium is provided to the processing chamber while the plasma treatment is suspended. Substrates may be flipped over for two-sided processing, and multiple substrates may be processed concurrently.
