Hard materials deep etch

Abstract: Глубокое травление кремния с применением Bosch-процесса или криогенных микротехнологий успешно исследуется и совершенствуется в течение уже нескольких десятилетий. Гораздо хуже изучено высокоскоростное направленное травление твердых материалов, применяющихся, например, в производстве МЭМС. В настоящей статье рассматриваются области применения твердых материалов в полупроводниковой промышленности, а также оборудование и процессы для их плазменного травления. Deep etching of silicon, achieved via Bosch or cryoge… Show more

“…However, even with deep etching (when the anisotropic properties of the material are used) the profile has a trapezoidal shape in depth. [13][14][15][16][17] Layerby-layer assembling of the structure does not solve the problem, since the number of applied layers is limited and precise alignment of the pattern is required at each stage. 8,13,18 Recently, photopolymerizable compositions (PPCs) sensitive to visible radiation, [19][20][21][22] which allow light to initiate nonuniform polymerization in the volume, have become increasingly popular.…”

“…Therefore, methods based on applying a topological pattern directly to the entire surface of a photoresist layer with further etching of the substrate could be more successfully used. However, even with deep etching (when the anisotropic properties of the material are used) the profile has a trapezoidal shape in depth 13–17 . Layer‐by‐layer assembling of the structure does not solve the problem, since the number of applied layers is limited and precise alignment of the pattern is required at each stage 8,13,18 …”
