Disclosed herein are a stretchable display panel and a stretchable device. The stretchable display panel comprises: a lower substrate having an active area and a non-active area surrounding the active area; a plurality of individual substrates disposed on the lower substrate, spaced apart from each other and located in the active area; a connection line electrically connecting a pad disposed on the individual substrate; a plurality of pixels disposed on the plurality of individual substrates; and an upper substrate disposed above the plurality of pixels, wherein the modulus of elasticity of the individual substrates is higher than that of at least one part of the lower substrate. Accordingly, the stretchable display device according to the present disclosure may have a structure that enables the stretchable display device to be more easily deformed when a user stretches or bends the stretchable display device and that can minimize damage to the components of the stretchable display device when the stretchable display device is deformed.

A method includes forming a fin on a substrate. A first liner is formed on the fin. A first dielectric layer is formed above the first liner. A patterned hard mask is formed above the first dielectric layer and has a fin cut opening defined therein. Portions of the first dielectric layer and the first liner disposed below the fin cut opening are removed to expose a portion of the fin. The patterned hard mask layer is removed. The exposed portion of the fin is oxidized to define a diffusion break in the fin.

A method for forming a semiconductor device includes providing a semiconductor substrate having an upper side and comprising, in a vertical cross-section substantially orthogonal to the upper side, a plurality of semiconductor mesas of a first monocrystalline semiconductor material which are spaced apart from each other by sacrificial layers selectively etchable with respect to the first monocrystalline semiconductor material and arranged in trenches extending from the upper side into the semiconductor substrate, forming on the semiconductor mesas a support structure mechanically connecting the semiconductor mesas, at least partly replacing the sacrificial layers while the semiconductor mesas remain mechanically connected via the support structure, and at least partly removing the support structure.

In some embodiments, silicon-filled openings are formed having no or a low occurrence of voids in the silicon fill, while maintaining a smooth exposed silicon surface. In some embodiments, an opening in a substrate may be filled with silicon, such as amorphous silicon. The deposited silicon may have interior voids. This deposited silicon is then exposed to a silicon mobility inhibitor, such as an oxygen-containing species and/or a semiconductor dopant. The deposited silicon fill is subsequently annealed. After the anneal, the voids may be reduced in size and, in some embodiments, this reduction in size may occur to such an extent that the voids are eliminated.

To provide a miniaturized transistor having highly stable electrical characteristics. Furthermore, also in a semiconductor device including the transistor, high performance and high reliability are achieved. The transistor includes, over a substrate, a conductor, an oxide semiconductor, and an insulator. The oxide semiconductor includes a first region and a second region. The resistance of the second region is lower than that of the first region. The entire surface of the first region in the oxide semiconductor is surrounded in all directions by the conductor with the insulator interposed therebetween.

Methods, devices, and systems associated with oxide based memory are described herein. In one or more embodiments, a method of forming an oxide based memory cell includes forming a first electrode, forming a tunnel barrier, wherein a first portion of the tunnel barrier includes a first material and a second portion of the tunnel barrier includes a second material, forming an oxygen source, and forming a second electrode.

A method of growing a nitride semiconductor layer may include preparing a substrate in a reactor, growing a first nitride semiconductor on the substrate at a first temperature, the first nitride semiconductor having a thermal expansion coefficient different from a thermal expansion coefficient of the substrate, and removing the substrate at a second temperature.

Methods of doping a semiconductor film are provided. The methods comprise epitaxially growing the III-V semiconductor film in the presence of a dopant, a surfactant capable of acting as an electron reservoir, and hydrogen, under conditions that promote the formation of a III-V semiconductor film doped with the p-type dopant. In some embodiments of the methods, the epitaxial growth of the doped III-V semiconductor film is initiated at a first hydrogen partial pressure which is increased to a second hydrogen partial pressure during the epitaxial growth process.

Methods of semiconductor arrangement formation are provided. A method of forming the semiconductor arrangement includes forming a first nucleus on a substrate in a trench or between dielectric pillars on the substrate. Forming the first nucleus includes applying a first source material beam at a first angle relative to a top surface of the substrate and concurrently applying a second source material beam at a second angle relative to the top surface of the substrate. A first semiconductor column is formed from the first nucleus by rotating the substrate while applying the first source material beam and the second source material beam. Forming the first semiconductor column in the trench or between the dielectric pillars using the first source material beam and the second source material beam restricts the formation of the first semiconductor column to a single direction.

Provided herein are methods of selectively etching silicon-containing block copolymer (BCP) materials. The methods involve exposing a BCP material that includes at least one silicon-containing block and at least one non-silicon-containing block to a plasma that has a reducing chemistry. The reducing plasma selectively removes the non-silicon-containing block, the silicon-containing block to be used in further processing. In some embodiments, the silicon-containing block is used as an etch mask. The reducing plasma reduces or eliminates profile bowing and undercut of the silicon-containing domains, allowing processing of high aspect ratio features. Examples of reducing chemistries include nitrogen (N.sub.2), hydrogen (H.sub.2), ammonia (NH.sub.3), hydrazine (N.sub.2H.sub.4), and mixtures thereof. Also provided are apparatuses to perform the methods.
