Thin film deposition is vital in chip manufacturing, creating micro devices by depositing films under 1 micron thick via CVD, ALD, or PVD. These processes build semiconductor components through alternating conductive and insulating films.

The main difference between epitaxy and atomic layer deposition (ALD) lies in their film growth mechanisms and operating conditions. Epitaxy refers to the process of growing a crystalline thin film on a crystalline substrate with a specific orientation relationship, maintaining the same or similar crystal structure. In contrast, ALD is a deposition technique that involves exposing a substrate to different chemical precursors in sequence to form a thin film one atomic layer at a time.

This article introduces the latest developments in the newly designed PE1O8 hot-wall CVD reactor of the Italian company LPE and its ability to perform uniform 4H-SiC epitaxy on 200mm SiC.

This article mainly introduces the product types, product characteristics and main functions of TaC Coating in semiconductor processing, and makes a comprehensive analysis and interpretation of TaC Coating products as a whole.

The semiconductor manufacturing process involves eight steps: wafer processing, oxidation, lithography, etching, thin film deposition, interconnection, testing, and packaging. Silicon from sand is processed into wafers, oxidized, patterned, and etched for high-precision circuits.

Diamond, a potential fourth-generation "ultimate semiconductor," is gaining attention in semiconductor substrates due to its exceptional hardness, thermal conductivity, and electrical properties. While its high cost and production challenges limit its use, CVD is the preferred method. Despite doping and large-area crystal challenges, diamond holds promise.
