Latest Patents
Hirota's latest patents include a forging roll device and a fabrication method for semiconductor integrated circuit devices. The forging roll device features a pair of roll axes that are parallel to each other, equipped with dies for shaping target materials. This device also includes a material holder/conveyer that facilitates the movement of materials between the roll axes. The design ensures that the outer circumferential surfaces of the roll axes are closer to a planar surface than a cylindrical surface, enhancing the forging process.
The fabrication method for semiconductor integrated circuit devices aims to prevent breakage of membrane probes during testing. This method involves using an appearance tester to evaluate the main surface of a wafer. Results indicating bad appearances, such as foreign substance adhesion or abnormal bump electrode shapes, are collected as wafer map data. This data is then transmitted to a probe tester, which omits tests for chips with detected issues while conducting tests on unaffected chips.
