In addition, the worm and worm groove depth of the pressure increased, in the end, reduce exhaust gate-rotor from the single slot, depth is zero, it does not exist.
此外，蜗杆的蜗杆槽深度随压力的增高而减少，在排气结束，星轮齿脱离单槽时，深度为零，故不存在余隙容积。
The gate region was fabricated by V-groove and Al sputtering, which can simplify the process, and make devices flexible in the adjustment process.
使用V形槽工艺，用溅射铝的方法代替扩硼工艺制备静电感应晶体管的栅极区，简化了工艺流程，使器件在调试过程中具有很大灵活性。
