Provided is a method of depositing an insulation layer on a trench in a substrate, in which the trench having an aspect ratio of 5:1 or more is formed, including: an insulation layer deposition step of performing an adsorption step of adsorbing silicon to the substrate by injecting a silicon precursor into the inside of a chamber into which the substrate is loaded, a first purge step of removing the unreacted silicon precursor and reaction byproducts from the inside of the chamber, a reaction step of forming the adsorbed silicon as an insulation layer including silicon by supplying a first reaction source to the inside of the chamber, and a second purge step of removing the unreacted first reaction source and reaction byproducts from the inside of the chamber; and a densification step of forming a plasma atmosphere in the inside of the chamber by applying an radio frequency (RF) power and densifying the insulation layer including silicon by using the plasma atmosphere, wherein a frequency of the RF power is in a range of 400 kHz to 2 MHz.

Method for depositing insulating film on recessed portion having high aspect ratio

Provided is a method of cyclically depositing a thin film including: performing an oxide depositing operation of repeatedly performing a deposition operation, a first purge operation, a reaction operation, and a second purge operation, wherein the deposition operation deposits silicon on a target by injecting a silicon precursor into a chamber into which the target is loaded, the first purge operation removes a non-reacted silicon precursor and a reacted byproduct from inside the chamber, the reaction operation supplies a first reaction source including oxygen into the chamber to form the deposited silicon as an oxide including silicon, and the second purge operation removes a non-reacted first reaction source and a reacted byproduct from the inside of the chamber; and performing a plasma processing operation of supplying plasma made of a second reaction source including nitrogen to the inside of the chamber to process the oxide including the silicon.

Cyclic deposition method for thin film and manufacturing method for semiconductor, and semiconductor device

A cyclic deposition method for thin film formation includes forming a silicon thin film on an object by injecting a silicon precursor into a chamber in which the object is loaded, depositing silicon on the object, and performing a first purge, removing an unreacted portion of the silicon precursor and reaction by-products from the interior of the chamber, pre-processing a surface of the silicon thin film by forming a plasma atmosphere in the chamber and supplying a first reaction source having a hydrogen atom, and forming the silicon thin film as an insulating film including silicon, by forming the plasma atmosphere in the chamber and supplying a second reaction source having one or more oxygen atoms, one or more nitrogen atoms, or a mixture thereof.
