Abstract: A semiconductor device includes a fin extending from a substrate and including a first fin end, a separation structure separating the first fin end from an adjacent fin end of another fin, a dummy gate spacer along sidewalls of the separation structure and the fin, a first epitaxial source/drain region in the fin and adjacent the separation structure, and a residue of a dummy gate material in a corner region between the dummy gate spacer and the first fin end. The first fin end protrudes from the dummy gate spacer into the separation structure. The residue of the dummy gate material separates the first epitaxial source/drain region from the separation structure and is triangle shaped.

Abstract: A process of forming a back side deep trench isolation structure for an image sensing device includes etching first trenches in the back side of a semiconductor substrate, lining the first trenches with dielectric, depositing passivation layers over and within the first trenches, and etching second trenches through the passivation layers into the first trenches, and filling the second trenches to form a substrate-embedded metal grid. Optionally, the bottoms of the first trenches are filled by depositing and etching a lower fill material prior to depositing the passivation layers. The method prevents the passivation layers from pinching off in a way that causes voids within the first trenches. The result is better optical performance such as increased quantum efficiency and reduced crosstalk.

Abstract: Fatty acids are produced through transacylation. An organic nitrogen-containing compound is reacted with alkyl sultone to generate a white solid of a zwitterionic compound. After being purified and dried, the white solid is powdered to be reacted with a Bronsted strong acid for obtaining a clear viscous water-based acidic ionic liquid (IL) as a catalyst used used to effectively process transacylation between oil and acetic acid (HOAc) for fabricating fatty acid (FFA) and glycerol triacetate (GTA). Therein, unsaturated fatty acid is simultaneously processed through addition acetoxylation to obtain stabilized acetoxy fatty acid (AFFA). After, HOAc is recycled through vacuuming. Then, the product and the IL are stratified. The product at upper layer is taken out. The IL at lower layer can be recycled for processing transacylation and addition acetoxylation repeatedly. Therein, fatty acids including the stabilized AFFA are obtained from the product after taking out GTA through vacuum distillation.
