Sumco Corporation (SUMCF)

Overview

Sumco Corporation operates in the semiconductor industry, primarily focused on the manufacturing and sale of silicon wafers. Serving a global market, it has its presence not only in Japan but also in significant semiconductor markets like the United States, China, Taiwan, Korea, and other international regions. The origins of Sumco Corporation trace back to its earlier incarnation as Sumitomo Mitsubishi Silicon Corp., undergoing a name change in August 2005. Incorporated in 1999, the company has established its headquarters in Tokyo, Japan, positioning itself as a crucial player in the semiconductor supply chain.

Products and Services

• Monocrystalline Ingots

Sumco Corporation provides high-quality monocrystalline silicon ingots, which are essential materials for the semiconductor manufacturing process. These ingots are the starting point for the creation of silicon wafers used in various electronic devices.

• Polished Wafers

The company offers polished wafers, which undergo a specific process to achieve a mirror-like finish. This polishing ensures the wafers are prepared for intricate semiconductor fabrication processes.

• Annealed Wafers

Sumco's annealed wafers are exposed to a controlled heat treatment to relieve internal stresses. This process improves the quality and durability of the wafers, making them suitable for advanced semiconductor applications.

• Epitaxial Wafers

The epitaxial wafers provided by Sumco are silicon wafers coated with an additional thin layer of monocrystalline silicon. This layer is dopable, allowing for precise electrical characteristics, critical in manufacturing semiconductors with specific functionalities.

• Junction Isolated Wafers

Junction isolated wafers are designed for use in applications that require isolating specific areas of the silicon wafer to prevent electrical interaction. This is crucial in creating complex semiconductor devices with multiple functionalities.

• Silicon-on-Insulator (SOI) Wafers

The SOI wafers produced by Sumco consist of a thin layer of silicon on top of an insulating layer, which itself rests on a silicon wafer. These wafers are utilized in high-performance semiconductor devices due to their superior efficiency and reduced power consumption.

• Reclaimed Polished Wafers

Committed to sustainability, Sumco also offers reclaimed polished wafers. These wafers have been previously used and are then polished again to be reused in less critical applications, reducing waste and promoting environmental consciousness in the semiconductor industry.
