Single‐crystal AlN grown on Al2O3is found to be wet etched by AZ400K photoresist developer solution, in which the active component is KOH. The etching is thermally activated with an activation energy of 15.5±0.4 kcalmol1, and the etch rate is found to be strongly dependent on the cryst...
Wet chemical etching through openings in photoresist or hard masks underlies many process sequences for MEMS device fabrication. This chapter presents more than 800 wet-etch recipes for over 400 varieties and combinations of substrates and deposited thin
An approach for wet-chemical atomic layer etching (WALE) of semiconductors is described. The surface chemistry of InAs was investigated for HCl/H2O2 solutions suitable for controlled etching in the low etch rate range (<0.1–10 nm min 1 ). Kinetic studies were performed using inductively coupled...

The first step of this process is to prepare the resonator with the correct etchant. This is important because dry oxide is difficult to bond to most materials, and the bonding between the layers is not uniform. A good etchant will reduce the roughness of the resulting silica circles. The...
solving these problems in the fabrication of pits is a promising research direction. Moreover, solar radiation in the infrared light range can increase the temperature of a solar cell, which may enhance the solar cell efficiency due to a forbidden gap value decrease. We consider this work as ...

(3)缓冲刻蚀剂缓冲刻蚀剂又叫作BOE(全称BufferedOxideEtch),是NH4F和HF以及表面活化剂的混合物,主要用来刻蚀晶圆上深槽里的氧化膜。根据NH4F和HF浓度比例的不同可分为MB、LB、DB。MB里NH4F与HF的比例是10:1,LB里NH4F与HF的比例是130:1,DB里NH4F与HF的比例是200:1。缓冲刻蚀剂与SiO2氧化膜的反应机理为:SiO2...
