华海清科获专利，抛光保持环达到目标形状后自动停止修整

11月6日，华海清科（688120）的发明专利《保持环修整装置、化学机械抛光单元及其控制方法和化学机械抛光设备》获授权，申请号为CN202511705507.1。

在化学机械抛光设备中，保持环的接触面也需要磨削修整。专利把修整盘、形状检测部件和控制器放进同一控制流程，抛光头使保持环与修整盘相对转动，检测部件取得被磨削面的形状。控制器确认形状达到设定条件后停止转动。停机依据是实际检测结果，目的是避免在形状已经合格后继续消耗修整资源。

截至此次授权消息披露时，华海清科今年获得的各类专利授权共99项，比上年同期增加22.22%。在2026年上半年，公司研发投入为2.75亿元，同比增长12.59%。企业知识产权记录中，华海清科股份有限公司名下可查到896条专利信息和39条著作权信息。
