A semiconductor device includes a stack structure of a conductive line and an insulating capping line extending in a first direction on a substrate, a plurality of contact plugs arranged in a row along the first direction and having sidewall surfaces facing the conductive line with air spaces between the sidewall surfaces and the conductive line, and a support interposed between the insulating capping line and the contact plugs to limit the height of the air spaces. The width of the support varies or the support is present only intermittently in the first direction. In a method of manufacturing the semiconductor devices, a sacrificial spacer is formed on the side of the stack structure, the spacer is recessed, a support layer is formed in the recess, the support layer is etched to form the support, and then the remainder of the spacer is removed to provide the air spaces.

A three-terminal synapse device may include a drain layer formed on a substrate, a gate layer formed on the drain layer, a source layer vertically stacked on the substrate and facing the drain layer and the gate layer. First and second vertical insulating layers may be formed between the source layer and a stack including the drain layer and the gate layer. The first and second vertical insulating layers have different ion mobilities from each other. The first and second vertical insulating layers may cover side surfaces of the drain layer and the gate layer. The ion mobility of the second vertical insulating layer may be greater than that of the first vertical insulating layer.

A monomer composition for polymerizing a branch-type silsesquioxane polymer is disclosed. The monomer composition includes hydroxy-substituted cyclic siloxane in a solvent, and the hydroxy-substituted cyclic siloxane includes stereoisomers of cyclic siloxane of cis, trans, random and twist structures at controlled ratios. Also disclosed are a branch-type silsesquioxane polymer synthesized by polymerizing the monomer composition for polymerizing a branch-type silsesquioxane polymer, and a method for synthesizing the same. In accordance with the disclosure, the isomers can be isolated stably at desired ratios. The isolated isomers may be polymerized into polymers of various types. Since the polymers exhibit low dielectric property, they may be utilized as low dielectric materials.

Disclosed is a novel use of a PPAR δ agonist, and more particularly, a fetal reprogramming effect of a PPAR δ agonist. A PPAR δ agonist adjusts calcium ion during embryo genesis and a early fetal development period to increase slow muscle fiber and to thus improve muscle endurance, thereby improving lipid and glucose metabolism and reprogramming the metabolism of the entire body, thus preventing/inhibiting the occurrence of metabolic diseases, such as obesity and diabetes in an adult body caused by a high-fat diet and a lack of exercise, and improving memory for an adult.
