Substrate processing method and substrate processing apparatus

In substrate processing, by supplying a first processing liquid onto an upper surface 91 of a substrate 9 held in a horizontal state, a liquid film 81 of the first processing liquid which entirely covers the upper surface 91 is formed. Further, by heating the substrate 9, a vapor layer 82 of the first processing liquid is formed between the upper surface 91 and the liquid film 81 of the first processing liquid on the upper surface 91. Then, by supplying a second processing liquid onto the upper surface 91 of the substrate 9, the liquid film 81 of the first processing liquid is removed from the upper surface 91. It is thereby possible to appropriately remove extraneous matters 89 from the upper surface 91 of the substrate 9, which are taken in the liquid film 81 of the first processing liquid as the vapor layer 82 is formed.

Provided is a method and apparatus for treating a substrate with a liquid. The substrate treating method comprises a pre-treating step for supplying the treatment liquid containing hydrogen fluoride (HF) to the substrate and treating the substrate before the surface modification step and a surface modification step for supplying an alkene-based chemical onto a substrate to change the surface of the substrate to a hydrophobic state. As a result, the surface of the substrate is uniform, and generation of particles can be reduced when the substrate is removed.

Glass carrier cleaning using ozone

In a method for removing an organic adhesive from a glass carrier in a semiconductor manufacturing process, the glass carrier is placed into a process chamber. The glass carrier is rotated and heated sulfuric acid is applied or sprayed onto the glass carrier. Ozone is introduced into the process chamber. The ozone diffuses through the sulfuric acid to the organic adhesive on the surface of the glass carrier. The sulfuric acid and the ozone chemically react with the organic adhesive and remove it from the glass carrier.

Substrate cleaning method, processing container cleaning method, and substrate processing device

A substrate processing device includes a processing container; a substrate holder configured to hold a substrate arranged within the processing container; a gas nozzle configured to spray gas within the processing container; a controller configured to control collision of the gas with the substrate held by the substrate holder. The controller is configured to remove particles adhering to the main surface of the substrate, by causing the vertical shock waves to collide with the main surface of the substrate.

Wafers on a first wafer carrier in a tank are lifted from the first wafer carrier and a bath in the tank so as to accomplish Marangoni drying of the wafers. The lifted dry wafers are positioned on a second wafer carrier in a chamber and shifted to an offset position. A barrier, which can be a wall of the chamber with or without a sweeping flow of gas, impedes the passage of deposits to the wafers arising during drying of the first wafer carrier. Static electricity can be discharged from wafer supports in the offset position.

A method for removing particles from a semiconductor wafer surface is disclosed. A wafer is being spun on a spin coater contained within a condensing environment. Liquid vapor is then infused into the condensing environment to allow some of the liquid vapor to be condensed onto a surface of the wafer on which particles may adhere while the wafer is being spun. Next, a set of light pulses is applied to the surface of the spinning wafer. Finally, an air stream is utilized to carry the particles off the surface of the wafer.
