  • Publication number: 20240047196
    Abstract: A selective thermal atomic layer deposition (ALD) process is disclosed. The process may comprise loading a substrate comprising a dielectric material, and a metal, into a reactor. The substrate may be reacted with a non-plasma based oxidant, thereby forming an oxidized metal surface on the metal. The substrate may be heated and exposed to a passivation agent that adsorbs more onto the oxidized metal than the dielectric material. Such exposure may form a passivation layer on the oxidized metal surface, and the substrate may be exposed to a silicon precursor that adsorbs more onto the dielectric material than the passivation layer, forming a chemi-adsorbed silicon-containing layer on the dielectric material. The substrate may be exposed to the non-plasma based oxidant, that simultaneously partially oxidizes the passivation layer, and oxidizes the chemi-adsorbed silicon-containing layer to form a silicon-containing dielectric film on the dielectric material.

  • Patent number: 9042142
    Abstract: The invention discloses a voltage source converter and a voltage source converter system. The voltage source converter comprises: a multi-level voltage source converter, being adapted to output a multiple levels of a first voltage at one of two first output terminals through a multiple of first conducting paths; a first energy store; and a first switching element, being arranged to directly connected with the first output terminal, and being adapted to switch the first energy store in or out of the first conducting path so as to combine a level of the voltage of the first energy store with the level of the first voltage as a second voltage output at a second output terminal. By having the topology as above, the voltage class of each of the power semiconductors can be kept lower with the number of the power semiconductors unchanged. Besides, VDRM is lowed as compared to conventional topology. This renders the reduction of the cost and the increase of the liability.
