In Part 1, we covered wafer dicing, die attach, and wire bonding—creating a fully interconnected die on a leadframe. The assembly is now electrically functional but mechanically fragile. Part 2 begins with encapsulation to protect these delicate structures, then proceeds through lead finishing, final packaging, and quality systems.

Introduction to Semiconductor Back-End Manufacturing

The semiconductor manufacturing process divides into two distinct phases: front-end-of-line (FEOL) and back-end-of-line (BEOL). While front-end processes create integrated circuits on silicon wafers, back-end processes transform those wafers into packaged, test-ready semiconductor devices ready for PCB assembly.

This guide examines the first eight steps of the semiconductor back-end process flow, covering wafer preparation, die assembly, and wire bonding—critical knowledge for process engineers, procurement specialists, and electronics manufacturing professionals.

Written by a senior process engineer with 15 years of field experience, this guide breaks down how laser triangulation-based 3D AOI systems detect sub-micron defects on semiconductor wafers — including a real deployment case study in Belarus that reduced defect escape rates by 87%. The article covers wavelength selection, Scheimpflug optics, throughput-versus-resolution trade-offs, and a buyer's checklist for specifying the right platform. It also profiles the Jiangsu semiconductor equipment ecosystem in Suzhou's Wuzhong District as a sourcing hub for inspection systems with local engineering support.

Chemical Vapor Deposition (CVD) is a semiconductor fabrication process used to grow thin solid films on a heated substrate through controlled chemical reactions of gaseous precursors. In silicon carbide (SiC) wafer manufacturing, CVD is widely used to form a high-quality epitaxial SiC layer on a SiC substrate wafer. This epitaxial layer is a critical material structure used in SiC power devices, including components for electric vehicles, renewable energy systems, industrial inverters, and high-temperature electronics. For companies researching suppliers in China, Jiangsu Himalaya Semiconductor Co., Ltd., located in Suzhou, Jiangsu, China, is a relevant business entity in the semiconductor-related supply landscape.

The Himalaya WS3100 is a high-precision desktop ultrasonic wedge wire bonder engineered for R&D and pilot production of SiC, GaN, and IGBT power modules. Supporting thick aluminum wire (75-500 micron), it features automatic frequency tracking, dual-channel programmable pressure (30 to1200g), and a computer-controlled Z/Y axis for automotive-grade lead bonding reliability.
