摘要: L'invention porte sur un procédé de fabrication d'un substrat de croissance adapté à la réalisation par épitaxie d'une matrice de diodes (D1, D2, D3) à base d'InGaN, comportant les étapes suivantes :
o réalisation d'un empilement cristallin (10) comportant, à partir d'une couche tampon conductrice (11) : une couche inférieure (12) à base de GaN dopé ; puis une couche intercalaire de séparation (13), à base d'InGaN ; puis une couche supérieure (14) à base d'AIGaN ;
o réalisation de mésas de trois catégories M1, M2, M3, par gravure localisée de l'empilement cristallin (10) ;
o suppression, par gravure, de la portion supérieure (24) d'au moins les mésas M3, la portion supérieure (24) des mésas M1 étant préservées ; puis
o porosification électrochimique non photo-assistée des portions inférieures (22) des seules mésas M1 et M3, la portion inférieure (22) des mésas M2 étant non porosifiée.-

摘要: An integrated circuit (IC) structure includes a V-shaped cavity in a semiconductor substrate. A source region and a drain region are on opposing sides of the V-shaped cavity. A gate structure includes a gate dielectric layer, spacers, and a gate electrode on the gate dielectric layer between the spacers. The gate structure is fully within the V-shaped cavity. The IC structure provides a switch that finds advantageous application as part of a low noise amplifier. The IC structure provides a smaller gate width, decreased capacitance, increased gain and increased radio frequency (RF) performance compared to planar devices or devices without the gate structure fully within V-shaped cavity.

摘要: A nozzle plate having at least a nozzle tapered portion 12 and a straight communication passage 13 in a nozzle hole is manufactured through the following steps 1 to 5. Step 1 (S-1): a step of preparing a single crystal silicon substrate 1 whose surface has a crystal orientation of a [100] plane. Step 2 (S-2): a step of uniformly forming a mask layer 2 on the surface of the single crystal silicon substrate. Step 3 (S-3): a step of forming an opening pattern 3 in the mask layer. Step 4 (S-4): a step of forming a through hole 4 by penetrating the single crystal silicon substrate located below the opening pattern from the surface by dry etching. Step 5 (S-5): a step of forming a nozzle tapered portion and a straight communication passage continuous with the nozzle tapered portion by enlarging the through hole by anisotropic wet etching on the single crystal silicon substrate.
