Methods, apparatuses, and systems related to forming a semiconductor using hybrid oxidation are described. An example method includes forming an opening to create an isolation region in a semiconductor substrate. The example method further includes depositing a first dielectric into the isolation region at a first oxidation rate. The example method further includes depositing a second dielectric into the isolation region at a second oxidation rate.

Semiconductor formation using hybrid oxidation

A device comprises an array of elevationally-extending transistors and a circuit structure adjacent and electrically coupled to the elevationally-extending transistors of the array. The circuit structure comprises a stair step structure comprising vertically-alternating tiers comprising conductive steps that are at least partially elevationally separated from one another by insulative material. Operative conductive vias individually extend elevationally through one of the conductive steps at least to a bottom of the vertically-alternating tiers and individually electrically couple to an electronic component below the vertically-alternating tiers. Dummy structures individually extend elevationally through one of the conductive steps at least to the bottom of the vertically-alternating tiers. Methods are also disclosed.

Some embodiments include an integrated assembly having digit-line-contact-regions between pairs of capacitor-contact-regions. The capacitor-contact-regions are arranged with six adjacent capacitor-contact-regions in a substantially rectangular configuration. Conductive plugs are coupled with the capacitor-contact-regions. Conductive redistribution material is coupled with the conductive plugs. Upper surfaces of the conductive redistribution material are arranged in a substantially hexagonal-close-packed configuration. Digit lines are over the digit-line-contact-regions. Insulative regions are between the digit lines and the conductive plugs. The insulative regions contain voids and/or low-k dielectric material. Capacitors are coupled with the upper surfaces of the conductive redistribution material.

An example apparatus includes forming a working surface of a substrate material. The example apparatus includes trench formed between two semiconductor structures on the working surface of the substrate material. The example apparatus further includes access lines formed on neighboring sidewalls of the semiconductor structures opposing a channel region separating a first source/drain region and a second source/drain region. The example apparatus further includes a time-control formed inhibitor material formed over a portion of the sidewalls of the semiconductor structures. The example apparatus further includes a dielectric material formed over the semiconductor structures to enclose a non-solid space between the access lines.

Methods, apparatuses, and systems related to selectively depositing a liner material on a sidewall of an opening are described. An example method includes forming a liner material on a dielectric material of sidewalls of an opening and a bottom surface of an opening and removing the first liner material of the sidewalls of the opening and the bottom surface of the opening using a non-selective etch chemistry. The example method further includes forming a second liner material on the dielectric material of the sidewalls of the opening to avoid contact with the bottom surface of the opening.

An array of elevationally-extending strings of memory cells comprises a vertical stack of alternating insulative tiers and wordline tiers. The wordline tiers have terminal ends corresponding to control-gate regions of individual memory cells. The control-gate regions individually comprise part of a wordline in individual of the wordline tiers. A charge-blocking region of the individual memory cells extends elevationally along the individual control-gate regions. Charge-storage material of the individual memory cells extends elevationally along individual of the charge-blocking regions. Channel material extends elevationally along the vertical stack. Insulative charge-passage material is laterally between the channel material and the charge-storage material. Elevationally-extending walls laterally separate immediately-laterally-adjacent of the wordlines. The walls comprise laterally-outer insulative material and silicon-containing material spanning laterally between the laterally-outer insulative material. The silicon-containing material comprises at least 30 atomic percent of at least one of elemental-form silicon or a silicon-containing alloy. Other aspects, including method, are also disclosed.

Apparatuses and methods are disclosed herein for densification of through substrate insulating liners. An example method may include forming a through substrate via through at least a portion of a substrate, forming a first liner layer in the through substrate via, and densifying the first liner layer. The example method may further include forming a second liner layer on the first liner layer, and densifying the second liner layer.

A disclosed example to modulate slit stress in a semiconductor substrate includes controlling a first process to apply a first material to a semiconductor substrate. The semiconductor substrate includes a slit between adjacent stacked transistor layers. The first material coats walls of the slit to reduce a first width of the slit between the adjacent stacked transistor layers to a second width. A second process is controlled to apply a second material to the semiconductor substrate. The second material is to be deposited in the second width of the slit. The first material and the second material are to form a solid structure in the slit between the adjacent stacked transistor layers.
