okamoto wafer grinding machine

wafer backside grinding 株式会社岡本工作機械製作所 バックグラインダー

・grinder for dedicated soi wafer which needs ultimate ttv level. ・each machine component adopt the low expansion material and avoid the chronological change by thermal deformation. removal amount control soft wafer is available as an option which enable submicron level layer thickness control with no effect of substrate thickness variation.

history - okamoto corporation

1926. kakusaburo okamoto established the okamoto special purpose machine tool works as a privately owned company. 1930. with its own technology the company developed an automatic spur gear grinding machine (model asg-2) regarded until then as the most difficult grinding machine to develop.
