The method includes the steps of forming a peelable resin layer on a silicon substrate, forming the wiring substrate on the peelable resin layer, mounting semiconductor chips on the wiring substrate, forming semiconductor devices by sealing the plurality of semiconductor chips by a sealing resin, individualizing the semiconductor devices by dicing the semiconductor devices from the sealing resin side but leaving the silicon substrate, peeling each of the individualized semiconductor devices from the silicon substrate between the silicon substrate and the peelable resin layer, and exposing terminals on the wiring substrate by forming openings through the peelable resin layer or by removing the peelable resin layer.

该方法包括以下步骤：在硅衬底上形成可剥离树脂层；在所述可剥离树脂层上形成布线衬底；将半导体芯片安装在所述布线衬底上；通过用密封树脂密封所述多个半导体芯片来形成半导体器件；通过从密封树脂侧将这些半导体器件切分但是保留硅衬底来使这些半导体器件个体化；将每个个体化半导体器件在所述硅衬底和可剥离树脂层之间从硅衬底上剥离；并且通过形成穿过可剥离树脂层的孔或者通过除去可剥离树脂层来使布线衬底上的端子暴露。

The study of screw seal with pulp was carried out in this paper and it was found that the screw parameters are different between screw seal with pulp and with oil.

摘 要：初步研究了以纸浆为密封介质的螺旋密封，结果表明，它与以油为介质的普通螺旋密封在螺旋参数选择上有所不同；其最高密封压力可达112 kPa，并且无需配置停机密封。

Composed of round door frames, gate, rack , sealing strip, adjustable structure of sealing , this kind of sealing principle is door frame is fixed on square pipe of pool and wall, rack is fixed on door frame and wall, through rack opens and closes till weld block of gate meets with weld block of rack to make sealing surface of gate close to sealing surface of door frame to achieve sealing .Besides , sealing of gate and sealing of door frame are made of inlaid copper which is well resistance ,It makes valve with well sealing ,wear resistance , corrosion resistance, easily operation, convenient installation , long life , wildly usage.

本闸门是由圆型门框、闸板、导轨、密封条、可调整密封机构等部件组成，其密封原理是门框固定于水池圆型管道及墙壁上，导轨固定门框与墙壁上，闸板通过导轨做启闭动作，直到闸板上的锲块碰到导轨条上的锲块，使得闸门密封面紧靠门框上的密封面，从而起到密封效果，另外闸板密封面跟门框密封面都是镶铜材质的，具有耐磨损的特性，使得阀门密封密封性好、耐磨性强、耐腐蚀、操作简单、安装方便、使用寿命长、适应性广等特点。
