Abstract:
1. A method of scribing a stuck mother substrate in order to obtain a plurality of stuck substrates from a stuck mother substrate in which a first mother substrate and a second mother substrate are stuck together, where the plurality of stuck substrates includes a first square of the first mother substrate and a second square of the second mother substrate stuck together so that one side of each of the square substrates are aligned while the other sides of each of the square substrates are not aligned so that unaligned side of the first mother substrate is offset from the unaligned side of the second mother substrate, the method of scribing the stuck mother substrate comprising: performing a first scribe process at a first predetermined strength on the second mother substrate which is stuck to the first mother substrate to form a full scribe line forming the unaligned side of the second substrate and to form a half scribe line which forms the unaligned side of the first mother substrate, the half scribe line being offset in a lateral direction from the full scribe line; and performing a second scribe process on the first mother substrate at a second predetermined strength which is weaker than the first predetermined strength in order to form a full scribe line to form the aligned side of the first substrate.
