  • Publication number: 20250023365
    Abstract: Simultaneous parallel charging of a first and second electrical energy storage devices coupled to a charge source is carried out by directly coupling the charge source to one of the first ESD and the second ESD and through a DC to DC converter to the other of the first ESD and the second ESD. The charge source provides a current that is allocated to the two ESDs by controlling the DC to DC converter. Priority of charging may be given to either ESD.

  • Patent number: 12191151
    Abstract: A method includes forming a gate stack, growing a source/drain region on a side of the gate stack through epitaxy, depositing a contact etch stop layer (CESL) over the source/drain region, depositing an inter-layer dielectric over the CESL, etching the inter-layer dielectric and the CESL to form a contact opening, and etching the source/drain region so that the contact opening extends into the source/drain region. The method further includes depositing a metal layer extending into the contact opening. Horizontal portions, vertical portions, and corner portions of the metal layer have a substantially uniform thickness. An annealing process is performed to react the metal layer with the source/drain region to form a source/drain silicide region. The contact opening is filled to form a source/drain contact plug.
