total thickness variation

基本解释

This paper studies the influence rule of the blade's vibration and the surface roughness, warp, total thickness variation (TTV) of the wafers, study the abrasi.
本文系统研究了内圆锯切过程中，锯片振动对硅晶片表面粗糙度、弯曲度、总厚度变化（TTV）的影响规律。
According to the theory of drying of liquid drop, Mathematical model of the total variation velocity of liquid film and increasing of coating thickness is gained by heat accounting.
在小液滴干燥理论基础上，通过质量和热量衡算，得到了包衣过程中颗粒表面液膜变化速率模型，包衣层厚度增长模型及颗粒质量增长线性模型，并对理论模型进行了修正。
Maximize the number of parts processed per load. The more parts in a machine load, the better the capability to overcome incoming part-to-part thickness variation and total thickness variation (TTV).
使每次抛光过程中砂轮所接触的产品部分总面积达到最大，这样的话，就能更好地克服抛光产品的各部分厚度变化和总体厚度变化（即TTV）。
