  • Patent number: 11949335
    Abstract: Apparatuses and methods related to a converter are disclosed. An apparatus includes a converter and a controller. The converter converts an input voltage potential to an output voltage potential. The input voltage potential and the output voltage potential include direct current (DC) voltage potentials. The controller generates pulse width modulation (PWM) signals responsive to a duty cycle control signal, controls the converter via the PWM signals in a buck mode when the duty cycle control signal is less than a predetermined maximum buck value, and controls the converter via the PWM signals in a cascaded buck-boost mode (CBB mode) when the duty cycle control signal is greater than the predetermined maximum buck value. A duty cycle of at least a portion of the PWM signals transitions linearly with the duty cycle control signal from the buck mode to the CBB mode.

    Abstract: A method of forming a partially silicided element is provided. A silicided structure including a silicide layer on a base structure is formed. A dielectric region is formed over the silicided structure. The dielectric region is etched to form a contact opening exposing a first area of the silicide layer and a tub opening exposing a second area of the silicide layer. A conformal metal is deposited to (a) fill the contact opening to define a contact and (b) form a cup-shaped metal structure in the tub opening. Another etch is performed to remove the cup-shaped metal structure in the tub opening, to remove the underlying silicide layer second area and to expose an underlying area of the base structure, wherein the silicide layer first area remains intact. The base structure with the intact silicide layer first area and removed silicide layer second area defines the partially silicided element.
