Abstract: PURPOSE:To make it possible to form an MES FET characterized by high drain withstanding voltage and excellent reliability at a high yield rate, by forming opening holes having a pent-roof type protruded part, and implanting ions so that ions pass the pent-roof type protruded part. CONSTITUTION:With a resist film 3 as a mask, an Si3N4 film 2 is etched by, e.g., a plasma etching method. Then, an SiO2 film 1 is etched by a fluoric acid etching liquid, e.g., ammonium fluoride, and opening holes 1a are provided in the SiO2 film. At this time, side etching is performed in the opening holes 1a in the SiO2 film so that the Si3N4 film 2 is protruded in a pent-roof shape. Thereafter, the resist film 3 is removed by, e.g., plasma ashing method. Then, ion implantation is performed under the conditions as follows: e.g., accelerating energy values of Si ions are 120keV and 250keV and dose amount is 2X10<13>/cm<3>. Annealing is performed at 850 deg.C and activation is carried out. Thus an N<+> layer 4 is formed.

Title: Thermally developable photosensitive material
Inventor: KATO MASATOSHI
IPC: G03C8/40
Filed: 1987-03-19
Abstract: PURPOSE:To obtain superior color balance independently of processing environment and processing conditions by incorporating an org. silver salt into at least one and not incorporating the salt into at least other one among of two or more photosensitive silver halide layers having different color sensitivities formed on a supporting body. CONSTITUTION:When two or more photosensitive silver halide layers having different color sensitivities are formed on a supporting body, an org. silver salt is incorporated into at least one of the layers and the salt is not incorporated into at least other one of the layers. The org. silver salt suppresses the reduction of the sensitivity when exposure is carried out at high temp. and the salt suppresses the retardation of development caused in case of a large amt. of supplied water, that is, low base concn. or pH. Accordingly, the org. silver salt is preferably incorporated into a photosensitive layer whose sensitivity is remarkably reduced at high humidity of a photosensitive layer which undergoes retarded development when a large amt. of water is supplied. Only by adjusting the org. silver salt-added layer and no the added layer, difference in change of sensitivity between the photosensitive layers having different color sensitivities is eliminated and an image having superior color balance is obtd. The difference is produced according to environment is which the resulting thermally developable photosensitive material is processed and conditions during the processing.
