Patent JP-H02288344-A (JP)
Title: Manufacture of charge transfer device
Inventor: OSAWA SHINJI
IPC: H01L29/762
Filed: 1989-04-28
Abstract: PURPOSE:To reduce a gap between transfer electrodes and to improve transfer efficiency by patterning a first layer transfer electrode and by forming a second transfer electrode using lift-off method thereafter. CONSTITUTION:A first layer transfer electrode 12' is formed using a third insulating film 14 as a mask which is selectively etched. A second layer transfer electrode 17' is further formed through lift-off method. The second layer transfer electrode 17' can be thereby formed by self-alignment. A second insulating film 13 is made to retreat from an edge section of the first layer transfer electrode 12' through isotropic etching to allow a part of the second layer transfer electrode 17' to overlap the first layer transfer electrode 12' securely. Therefore, a transfer electrode can be made in double layer structure, independent of a length of a first layer transfer electrode. Thereby, it is possible to reduce a size per one transfer step and to form a transfer electrode in double layer electrode structure, thereby minimizing a gap between electrodes and to improve transfer efficiency of a signal charge.
