History

(As of Jan.2007)

Jan.2000
Sony Chemicals Corporation

Became a wholly-owned subsidiary of Sony Corporation in response to the structural reorganization of Sony Corporation. (Sony Chemicals Corporation was delisted from TSE.)

Apr.2000
Sony Miyagi Corporation
Established Sony Miyagi Corporation.

The manufacturing division and production engineering unit within Sendai Technology Center of Sony Corporation (the present Tagajyo Plant) and Sony Precision Magnetics Corporation (the present Nakada and Toyosato Plants) were unified to form Sony Miyagi Corporation, which serves as a production site for recording medias and magnetic devices.

Sony Miyagi Corporation
Started production of Sony "FeliCa" format IC card.

As the non-contact IC cards became widely available, the market for "FeliCa" format IC card expanded rapidly.
This year, in 2000, the company started production of IC cards for transportation tickets.
Accordingly, the company also introduced the latest plant security features required for such card production and established a completely new set of systems dedicated to the mass production of antenna-integrated card products, with the technical support of Sony Corporation. This support included expertise in flip chip bonding, telecommunications, and development technologies for inspection and testing software. At present, the company produces and delivers IC cards intended primarily for transportation systems in Hong Kong, Singapore, India, Thailand and other Asian countries as well as Japan.

Oct.2001
Sony Miyagi Corporation
Started production of Touch screen.

Based on know-how accumulated over the years of manufacturing and production engineering of various devices, the company successfully introduced the film-glass resistive touch screens in 2001. Encouraged by a good reputation for stronger glass due to the adoption of a super-cutting design, the company made a full-scale entry into the touch screen market space. The touch screen products have been finding applications in the fields of PDAs, smart phones, and PNDs by a number of providers because of their well-balanced quality and reliability.
In addition, equipped with the additionally developed high transparency and low reflection film, the touch screens are well received as easy-on-the-eye displays.

Jan.2002
Sony Chemicals Corporation
Started selling of Anti-reflection film.

Sony Chemicals Corporation established the roll-to-roll sputtering system suited for volume production by applying the proprietary technology for Anti-reflection film for cylindrical CRTs, which had been developed by Sony Corporation. Sony Chemicals Corporation started selling of the sputtering thin film "Ant-ireflection film" intended for LCDs, game machines, and cellular phones.
The company has added a new product line of higher value-added "filter-oriented materials", aiming to expand the business in various domains.

Apr.2002
Unification of Sony Chemicals Corporation and Sony Neagari Corporation

Sep.2002
Started selling of UV curable adhesive for optical pickup

As recording media shifted from analog to digital formats and optical modules were coming out with higher resolutions, the demand for semiconductor modules grew. Driven by this trend, the UV curable adhesive for optical pickup was developed.

Apr.2003
Sony Miyagi Corporation
Started production of Blu-ray Disc.

In response to the introduction of a Blu-ray Disc player Model BDZ-S77 capable of recording high-definition (HD) video, production of Blu-ray Disc Model BF23G was started. Making full use of their know-how about conventional optical disk production, the company established a full-blown mass-production system backed by the technical support of Sony Corporation for the cover layer formation, high-precision mastering, and phase change recording layer deposition technologies.

Jan.2004
Sony Chemicals Corporation
Started production of high-density mounting double-sided flex-rigid printed circuit board

In order to support further downsizing and higher density mounting, the NORTH Corporation's NMBI (Neo Manhattan Bump Interconnection) technology was adopted and the high-density mounting double-sided flex-rigid printed circuit board was developed and adopted in the DVD Handycam DCR-DVD101/201, and additionally incorporated in the Hi-Vision Handycam models FX-1 and HC-1. This board is expected to find application in mobile camera module such as cellular phones.

Aug.2004
Sony Chemicals Corporation
Started selling of thermal conductive sheet

As integrated circuits are coming out with advanced features and reduced sizes, protection against elevated temperatures is essential for notebook personal computers and liquid crystal displays. The thermal conductive sheet was developed to efficiently dissipate heat from circuit boards even if mounted in closed enclosures. The thermal conductive sheet is expected to find wide application in various fields.

Feb.2006
Sony Chemicals Corporation
Development of lump-sum lamination Any Layer multilayer printed circuit board

The H-SAT (High Speed transmission All layer via Thin PWB) lump-sum lamination Any Layer multilayer printed circuit board was developed, which could contribute to reduce both time-to-market and man-hours. It became possible to develop a lump-sum lamination circuit board using materials of low dielectric constant and low dielectric loss and to produce boards with excellent high-speed transmission features on short lead times.

Jul.2006
Establishment of "Sony Chemical & Information Device Corporation"

Unification of "Sony Chemicals Corporation" and "Sony Miyagi Corporation".
