Systems and methods for automatic concentration control
Semiconductor processing systems and methods are provided in which an amount or concentration of a chemical in a chemical mixture contained in a tank is automatically controlled based on a sensed properties of the chemical mixture. In some embodiments, a semiconductor processing system includes a processing tank that is configured to contain a chemical mixture. A chemical sensor is configured to sense one or more properties of the chemical mixture. The system further includes an electrically controllable valve that is configured to adjust an amount of the first chemical in the chemical mixture based on the sensed one or more properties of the chemical mixture.
Selective deposition of a passivation film
Selective deposition methods are described. An exemplary method comprises exposing the substrate comprising a first surface and a second surface to an anchor reactant and selectively depositing the anchor reactant on the first surface as a seed layer, wherein the anchor reactant comprises an ethynyl derivative with a headgroup that selectively targets the first surface.
CLEANING METHOD OF CUP OF SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING APPARATUS
A cleaning method includes (A) and (B) described below. (A) A first processing liquid is supplied to a central portion of a top surface of a substrate from a first nozzle and, also, a second processing liquid is supplied to a periphery of the top surface of the substrate from a second nozzle in a state that the substrate is horizontally held inside a cup and the substrate is rotated in a first direction about a vertical rotation shaft. (B) During a discharge of the second processing liquid by the second nozzle, the second nozzle is moved in a diametrical direction of the substrate between a first position where a discharge line of the second nozzle touches the periphery of the top surface of the substrate and a second position where the discharge line of the second nozzle deviates from the substrate.

TRANSFER UNIT, AND APPARATUS AND METHOD FOR TREATING SUBSTRATE
Disclosed are an apparatus and a method for liquid-treating a substrate. An apparatus for treating a substrate includes a liquid treatment chamber that supplies a liquid onto the substrate to liquid-treat the substrate, a drying chamber that removes the remained liquid on the substrate, and a transfer unit that transfers the substrate between the liquid treatment chamber and the drying chamber, wherein the transfer unit includes a hand that supports the substrate, and a weight measuring unit that measures a weight of the remained liquid on the substrate. A weight of a remained liquid on a substrate may be measured by measuring a weight of the substrate while the substrate is transferred.
APPARATUS AND METHOD FOR TREATING SUBSTRATE
Disclosed are an apparatus and a method for liquid-treating a substrate. An apparatus for treating a substrate includes a liquid treating unit that liquid-treats a substrate by supplying a liquid onto a substrate, a weight measuring unit that measures a weight of the remained liquid on the substrate, and a transfer unit that transfers the substrate between the liquid treating unit and the weight measuring unit.

Substrate processing method and substrate processing apparatus
A method includes: supplying a processing liquid to a center position of a substrate surface; shifting a supply position of the processing liquid from the center position to a first eccentric position; holding the supply position of the processing liquid at the first eccentric position and supplying a substitute liquid to a second eccentric position; shifting the supply position of the processing liquid in a direction away from the center position, and shifting a supply position of the substitute liquid to the center position; and supplying the processing liquid to the first eccentric position at a first flow rate, and reducing the flow rate of the processing liquid to a second flow rate after the supply position of the processing liquid starts to be shifted from the first eccentric position in the direction and until the supply position of the substitute liquid reaches the center position.
Wafer dryer apparatus and method
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.
