Faster Wafer Characterization for Semiconductor R&D<\/strong><\/h3>\n\n\n\n

TWHM 2026 (16th Topical Workshop on Heterostructure Microelectronics) will be held from Monday, August 24 to Thursday, August 27, 2026, at Hotel Ichibata in Matsue, Shimane Prefecture, Japan. Seiken will participate in the event and showcase Buzmic, a semiconductor wafer evaluation system designed for electrical characterization.<\/p>\n\n\n\n

Since its establishment in 1994, TWHM has brought together researchers and engineers working on microelectronics based on semiconductor heterostructures. The workshop provides a forum for sharing the latest research and technological developments in areas including semiconductor materials and evaluation, device physics, process technology, circuit design, and system applications.<\/p>\n\n\n\n

TWHM 2026 will cover a broad range of advanced semiconductor technologies, including heterostructure materials, Group III nitride semiconductors such as GaN, high-frequency, high-speed and THz devices, power electronics, sensors, manufacturing technologies, and reliability.<\/p>\n\n\n\n

At this year’s event, Seiken will introduce Buzmic (Semiconductor Carrier Analyzer), an advanced system for evaluating the electrical properties of semiconductor wafers.<\/p>\n\n\n\n

Buzmic: Advanced Electrical Characterization of Semiconductor Wafers<\/strong><\/h4>\n\n\n\n

In semiconductor research and development, understanding the electrical properties of semiconductor wafers is essential for evaluating materials, optimizing manufacturing processes, and developing next-generation devices.<\/p>\n\n\n\n

This is particularly important for wide-bandgap semiconductors such as GaN, where parameters including sheet resistance, carrier concentration, and carrier mobility<\/strong> provide valuable insight into material properties and process conditions.<\/p>\n\n\n\n

Buzmic provides researchers and engineers with a practical approach to semiconductor wafer electrical characterization, helping them obtain important electrical-property data efficiently during R&D and process evaluation.<\/p>\n\n\n

Evaluate Semiconductor Wafers Without Forming Metal Electrodes<\/strong><\/h4>\n\n\n\n

Conventional four-point probe measurements and Hall measurements often require the formation of metal electrodes on the measurement sample. This additional preparation can increase measurement time and complicate the evaluation process.<\/p>\n\n\n\n

Buzmic enables both four-point probe measurements and Hall measurements without forming metal electrodes<\/strong> on the wafer. By simplifying sample preparation, Buzmic can efficiently evaluate key semiconductor parameters such as sheet resistance, carrier concentration, and carrier mobility.<\/p>\n\n\n\n

This makes Buzmic particularly useful for semiconductor material research, wafer evaluation, and process development, where rapid and flexible electrical characterization can support faster R&D cycles.<\/p>\n\n\n\n
