  • Publication number: 20240060180
    Abstract: Provided is a method for depositing a metal thin film by atomic layer deposition (ALD) using an organometallic complex as a source material and without using radical species such as plasma and ozone, which have a possibility of deactivation. The method is an atomic layer deposition (ALD) method for metal thin films which includes: a process of supplying an organometallic complex having an aromatic anionic ligand and/or an alkyl ligand into a reaction chamber in which a substrate is installed; and a process of supplying a mixture gas containing a nucleophilic gas and an electrophilic gas into the reaction chamber, the ALD method substantially not using either one of a gas in a plasma or radical state and a gas containing oxygen atoms.

  • Patent number: 8826769
    Abstract: A steering device includes an outer column including fastening pieces formed to face each other at both sides, in the width direction, of a slot portion formed at either of a lower side or an upper side of an embracing body portion along an axial direction thereof, a fixed bracket clamping the outer column, a fastener that fastens the outer column and the fixed bracket, an inner column, and a pushing member having an expanding shaft portion. The two fastening pieces of the embracing body portion are connected by the fastener so that the two fastening pieces can be expanded and contracted, and the expanding shaft portion is elastically biased in an axial center direction of the outer column so as to abut on end zones of the slot portion and expand the two fastening pieces.
