Title: Washing water repellent and dicing method using the same
Inventor: SUZUKI MUTSUMI
IPC: H01L21/304
Filed: 1994-12-14
Abstract: PURPOSE: To prevent the adhesion of cut refuse generated at the time of dicing to the surface of a wafer by using a compd. having the bonding region bonded to SiO2 on the surface of a substrate and a hydrophobic resion as the washing water repellent applied to the substrate before the washing with pure water when the surface of the substrate having plurality of elements formed thereon is divided at every element. CONSTITUTION: An N-type diffusion layer 2 is provided to a P-type Si substrate 1 and a PN photodiode is formed by the P-type Si substrate 1 and the N-type diffusion layer 2. Each PN photodiode corresponds to one light detection part of a multi-split photosensor. Next, an SiO2 membrane 3 protecting the PN photodiode is formed on the surface of the photodiode. A compd. having a bonding region reacting with the OH group on the surface of a wafer and a hydrophobic region repelling water is applied to the surface of the wafer before dicing not only to remove a hydrophilic OH group but also to substitute a position where an OH group is present with the hydrophobic region (layer 4). By this constitution, pure water in which cut refuse is taken at the time of dicing is repelled and does not remain on the surface of the wafer.
