Advantest Corporation, incorporated in December 1954, is a part of Advantest group. The Company operates in three segments: semiconductor and component test system segment; mechatronics system segment, focusing on peripheral devices including test handlers and device interfaces, and services, support and others segment. The semiconductor and component test system segment provides customers with test system products for the semiconductor industry and the electronic component industry. The mechatronics system segment focuses on peripheral devices to the semiconductor and component test systems. The services, support and others segment consists of comprehensive customer solutions provided in connection with the semiconductor and component test system and mechatronics system segments, support services and an equipment lease business.

Semiconductor and Component Test Systems Segment

Semiconductor and component test systems are used during the semiconductor and electronic component manufacturing process to confirm that a semiconductor functions properly. Semiconductor and component test systems consist of test systems for memory semiconductors and test systems for non memory semiconductors. Advantest’s test systems for memory semiconductors are test systems designed to test high-speed/high performance dynamic random access memory (DRAM) semiconductors used in equipment such as personal computers and servers, as well as flash memory semiconductors used in digital consumer products.

Test systems for memory semiconductors consist of a mainframe and one or more test heads. During testing, a device interface is attached to the test head. During the front-end testing process, wafers are loaded by a prober and are connected to the test system for memory semiconductors through the device interface. Electric signals between the die and the test systems for memory semiconductors are transmitted through probe pins located in the device interface and tested. After front-end testing is completed, the wafer is diced into separate dies and properly functioning dies are packaged. During back-end testing, test handlers are used to load these packaged devices onto the test heads, and electric signals are transmitted between the devices and the test heads via the device interface and tested. The test results are analyzed by the test systems for memory semiconductors’ hardware circuits and software programs. Customized software programs for each semiconductor are required to analyze the semiconductor tests and test data.

Advantest’s main product lines of test systems for memory semiconductors are the T5500 series, the T5300 series and the T5700 series. The T5593 is a test system targeted at the market for high speed memory semiconductors, such as DDR2- Synchronous Dynamic Random Access Memory (SDRAM) and Synchronous Graphics Random Access Memory (SGRAM). The T5383 is a multi-functional test system for memory semiconductors that reduces testing costs for semiconductor manufacturers. Advantest’s main line of test systems for non memory semiconductors relates to test systems for SoC semiconductors, test systems for liquid crystal display (LCD) driver integrated circuits and test systems for semiconductors used in car electronics. The T6577 test systems for SoC semiconductors in the T6500 series were primarily developed to test micro controller unit (MCU) and SoC semiconductors that control digital consumer products at the production lines. The T6300 series are test systems for LCD driver integrated circuits used with high-definition LCD displays. The T7721, T7722 and T7723 are test systems for non memory semiconductors for mixed signal integrated circuits. The T8571A is a test system for non memory semiconductors that is primarily used to evaluate and analyze CCDs which are image sensors.

Mechatronics System Segment

The Main products in the Mechatronics System Segment are test handlers which handle semiconductor devices and automate the testing, and device interfaces which are the interfaces with devices being tested. Test handlers are used with semiconductor and component test systems to handle, condition temperature, contact and sort semiconductors and other electronic components during the back-end testing of the semiconductor manufacturing process. Advantest’s test handlers are sold primarily in conjunction with the sale of its semiconductor and component test systems. The M6242 test handler for test systems for memory semiconductors, including DDR-3SDRAM, can handle up to 512 semiconductors at a time. Advantest’s test handlers for non memory semiconductors, including SoC semiconductors, are the M4841, the M4741A and the M4742A, among others.

Advantest develops and manufactures device interfaces for semiconductor and component test systems and supplies device interfaces, such as high performance and high density connectors, socket boards and sockets. For test systems for memory semiconductors, Advantest provides motherboards capable of handling a maximum of 512 semiconductors at a time. For test systems for non memory semiconductors, Advantest provides motherboards that are compatible with a maximum of 3,072 signals. Advantest also provides motherboards designed for use in front-end testing. Advantest provides custom manufacturing of socket boards and performance boards for each device under test in accordance with customers’ specifications.

Advantest provides sockets for test systems for memory semiconductors. Advantest provides low-inductance (0.4nH) sockets and fine pitch (0.4mm) sockets for semiconductors that are becoming more high-speed and more compact in size. Advantest provides carrying and contacting mechanism components compatible with each device under test for test handlers for memory semiconductors and test handlers for non memory semiconductors.

Services, Support and Others Segment

In the services, support and others segment, Advantest has focused on maintenance services, such as installation and repair of Advantest’s products. It also focused on lease and rental services of its products as a part of Advantest’s effort to provide customers with comprehensive solutions.

The Company competes with Teradyne, Inc., Verigy Ltd., LTX-Credence Corporation, Yokogawa Electronic Corporation, FROM30 CO., LTD., EXICON Ltd., UniTest Inc., Delta Design, Inc., Seiko Epson Corporation, Mirae Corporation, TechWing, Inc., TSE Co., Ltd. and Secron Co., Ltd.
