发明名称 Polishing holder for silicon wafers and method of use thereof
摘要 An method and apparatus for forming wafers of varying thickness'. The apparatus includes a template. The template is formed of a main disk including a plurality of cavities extending into a first side thereof. Each cavity has notches cut in the walls thereof and a pattern etched in the base thereof. Holding disks are moistened and positioned within respective cavities for releasably securing a wafer in the cavity. A moistening liquid is dispensed and diffuses into the cavities via the notches cut in the walls and collects in the pattern etched on the base of the cavity thereby increasing the suctional force used to secure the holding disk. When the template is releasably secured within a cavity, rotatably connected to a rotating head and positioned such that the first side faces a lapping and polishing surface, wafers received by the cavities are lapped and polished upon rotation of the rotating head.
