近年来,母盘制造技术得到了人们更多的关注,出现许多新亮点,新厂家进入了这个市场,不少厂家在老设备上使用了新技术和新工艺。例如大多母盘设备激光刻录部分采用半导体激光器技术,减小了设备体积,延长了激光器的使用寿命,简化了激光刻录光路,使光路的调整更为方便简单;许多母盘设备刻录速度已达到CD 8倍速、DVD 3倍速;一些设备采用UV照射工艺去除电铸后压模表面的光刻胶;在感光材料选用方面,染料聚合物技术是刻录时写后直读,利用闭环反馈技术实时回放读取信息,根据反馈信号可优化调整激光刻录能量,并可检查出刻录错误和缺陷,以利于及时中断刻录,
In recent years, the master disk manufacturing technology has attracted more attention, there are many new bright spots, the new manufacturers to enter this market, many manufacturers in the old equipment, the use of new technologies and new processes. For example, most of the laser equipment used in semiconductor laser equipment, semiconductor laser technology is adopted to reduce the volume of the equipment and prolong the service life of the laser, which simplifies the laser light path and makes the adjustment of the light path more convenient and simple. 8x speed, DVD 3x speed; some equipment using UV irradiation process to remove the electroformed stamper after the surface of the photoresist; in the selection of photosensitive materials, the dye polymer technology is written when recording direct reading, closed loop feedback technology real-time playback read Take information, according to the feedback signal can be optimized to adjust the laser recording energy, and can check out the recording errors and defects, in order to facilitate the timely interruption of recording,
