WebLow-temperature co-fired ceramics (LTCC) are used to fabricate robust multilayer circuits. Typically, thick-film technology is applied for metallization. For specific sensor applications, thin films are deposited directly on the as-fired LTCC-surface. These deposited thin films are structured either by lift-off or by etching. The latter is less error-prone and thus preferred … Web25 feb. 2024 · This paper reports on the use of low-damage atomic layer etching (ALE) performed using O2 and BCl3 plasma for etching (Al)GaN. The proposed ALE process led to excellent self-limiting etch characteristics with a low direct current (DC) self-bias, which resulted in a high linearity between the etching depth and number of cycles.
The two fundamental types of etchants are liquid-phase ("wet") and plasma-phase ("dry"). Each of these exists in several varieties. The first etching processes used liquid-phase ("wet") etchants. This process is now largely outdated, but was used up until the late 1980s when it was superseded by dry plasma etching. The wafer can be immersed in a bath of et… WebIn an advanced state of bearing rolling contact fatigue, dark etching regions (DERs) can be found as well as white etching, low- angle bands (LABs) and high-angle bands (HABs) (fig. 4 left). Although LABs and HABs are white etching too, they have a diferent appear - ance compared with irregular WEC formations found in early bearing failures.
Web2 mei 2024 · To achieve low contact resistance between metal and III-V material, transmission-line-model (TLM) structures of molybdenum (Mo) were fabricated on indium phosphide (InP) substrate on the top of an indium gallium arsenide (InGaAs) layer grown by molecular beam epitaxy. The contact layer was prepared using a digital etch procedure …
WebN or O was used to etch W and poly-Si, the etch rates22 were very low.
