摘要:
In one embodiment, die are singulated from a wafer having a back layer by placing the wafer onto a first carrier substrate with the back layer adjacent the carrier substrate, forming singulation lines through the wafer to expose the back layer within the singulation lines, and using a mechanical device to apply localized pressure to the wafer to separate the back layer in the singulation lines. The localized pressure can be applied through the first carrier substrate proximate to the back layer, or can be applied through a second carrier substrate attached to a front side of the wafer opposite to the back layer.

在一个实施例中,通过将晶片放置在第一载体衬底上,使背面层与载体衬底相邻,将晶片放置在具有背层的晶片上,形成单晶线以暴露分离线内的背层,并使用 将局部压力施加到晶片以分离分离线中的背层的机械装置。 局部压力可以通过靠近背层的第一载体衬底施加,或者可以通过附接到与背层相对的晶片的前侧的第二载体衬底施加。
