Silicon dioxide ( Si O 2 ) films grown on single crystal Si in high temperature O 2 were etched using nonaqueous HF/pyridine solutions in supercritical C O 2 . The etch rate of Si O 2 films were studied in the solutions with HF concentration up to 1000 渭 M at 1.38 脳 10 7 Pa ...
RF可用四探针测量法。Xj可用倾斜研磨 (Angle lapping) 和染色 (staining) 法,(如用HF:H3PO4 = 1:6 使P层黑化),或扩展电阻( spreading resistance) 法来进行评估。倾斜研磨后,经侵蚀的酸溶液蚀刻,将guttering后集积在晶片下半部的析出物凸显出来,显现出密度的轨迹,而在靠晶片的表面附近出现 一段空泛区,经...
An HF/HO vapor etching technique has been applied as a sacrificial oxide etching process step in surface-micromachining technology. This technique does not suffer from the notorious problem known as stiction, i.e., permanent attachment of movable structures to the underlying substrate during drying ...
显然反应速率与𝐅−和𝑯++的浓度有关,因此在腐蚀过程中通常加入氟化铵(𝐍𝐇4𝐅)作为缓冲剂,𝐍𝐇4𝐅能够电离生成𝐅−以补充随着反应推进而逐渐减少的𝐅−数量,并使HF电离平衡向左移动,调节溶液的PH值,以减轻腐蚀液对光刻胶的腐蚀作用。加入𝐍𝐇4𝐅的HF溶液称为BOE(bufferedoxideetching)...
Since the plasma is confined near a quartz plate, HF molecules generated from the reaction of H atoms with F atoms do not undergo dissociation in the diffusive region. Thus high-speed pumping of HF is considered to suppress Si etching and in turn, to allow highiy selective SiOetching. 展开...
