Title: Partial etching of silicon substrate
Inventor: KONDO MASAO
IPC: H01L21/306
Filed: 1985-04-24
Abstract: PURPOSE:To obtain a highly accurate recessed portion by a single specification when the recessed portion is formed by etching in a portion of an Si substrate by forming a polycrystalline Si film on the surface of the substrate and etching also the Si of the portion which is desired to be etched while etching polycrystalline Si left after the etched portion is removed. CONSTITUTION:An SiO2 film 2 is coated on an Si substrate 1 and a polycrystalline Si film 3 is piled on the film 2, where the film 3 is made to have a thickness t1 of the degree that it is reduced to zero when a recessed portion is formed in the substrate 1 by etching it in an after process. Then, after a photoresist mask 4 with an opening opposite to the recessed portion is provided on the film 3, first the portion of the film 3 exposed in the opening is removed by dry etching using plasma or the like and then the film 2 is also removed by using a solution of hydrofluoric acid/nitric acid. At this time, the surface portion of the substrate 1 that is exposed due to the removal of the film 2 is also removed by etching at the same time to obtain the recessed portion with a desired depth t2 in the surface of the substrate 1, thereby being suited to the formation of IC's including I<2>L thereon.

In this case, the 2nd identification information is recorded for an idle time for a vertical blanking period and gives no effect of disturbance onto a synchronizing signal and the picture information. Furthermore, in the case of reproducing the still picture, since the 2nd identification information is retrieved at a usual reproduction speed after high speed retrieval of the 1st identification information, the picture information of the specific still picture is surely and quickly detected.
