    Abstract: In an example, a method of forming a stacked memory array includes, forming a termination structure passing through a stack of alternating first and second dielectrics in a first region of the stack; forming first and second sets of contacts through the stack of alternating first and second dielectrics in a second region of the stack concurrently with forming the termination structure; forming an opening through the stack of alternating first and second dielectrics between the first and second sets of contacts so that the opening terminates at the termination structure; and removing the first dielectrics from the second region by accessing the first dielectrics through the opening so that the first and second sets of contacts pass through the second dielectrics alternating with spaces corresponding to the removed first dielectrics.

    Abstract: Semiconductor device assemblies having stacked semiconductor dies and thermal transfer devices that include vapor chambers are disclosed herein. In one embodiment, a semiconductor device assembly includes a first semiconductor die, a second semiconductor die on a base region of the first die, and a thermal transfer device attached to a peripheral region of the first die and extending over the second die. The thermal transfer device includes a conductive structure having an internal cavity and a working fluid at least partially filling the cavity. The conductive structure further includes first and second fluid conversion regions adjacent the cavity. The first fluid conversion region transfers heat from at least the peripheral region of the first die to a volume of the working fluid to vaporize the volume in the cavity, and the second fluid conversion region condenses the volume of the working fluid in the cavity after it has been vaporized.
