Title: Semiconductor memory
Inventor: YAMASHITA KAZUHIRO
IPC: H01L21/30
Filed: 1986-06-12
Abstract: PURPOSE:To form a multilayered structure of heterogeneous impurities on a resist surface so that this process can be simplified, by serially radiating multilayer ions by means of a similar device. CONSTITUTION:A resist pattern 1 is formed on a semiconductor 2, and then H<+> ions 3 are implanted in the pattern 1 by means of acceleration voltage 50 KV to form an implantation layer 4. Successively H ions 5 are implanted by means of acceleration voltage 20 KV to form an implantation layer 6. Ranges of the H<+> ions in the resist are 0.6 mum in the case of the acceleration voltage 50 KV, and 0.3 mum in the case of the acceleration voltage 20 KV, respectively as regards a PMMA resist, and therefore two-layer structure comprising the layers 4 and 6 different in radiation amount of H<+> ions is formed in the resist. When the substrate 2 is soaked with a mixing liquid of MIBK and IPA, only the layer 4 is etched at an etching speed based on the amount of H<+> ions, to form a resist pattern 7 whose cross section is shaped in character T.

Title: Sustained release freshness retainer
Inventor: KURANARI KENJI
IPC: A23B7/152
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain a sustained release freshness retainer which can retain the freshness over a long period and is useful for storing citruses, meats, fishes, shellfishes, and so on, by sealing a carrier adsorbing a volatile freshness- retaining component in a closed container formed from a specific laminated film. SOLUTION: This sustained release freshness retainer is obtained by sealing a carrier, such as cyclodextrin or silica, adsorbing a volatile freshness-retaining component, such as isothiocyanate compound or cinnamic aldehyde, in a closed container formed from a laminate film which comprises a perforated film and a sealant layer disposed on at least one surface of the perforated film. The perforated film is obtained by perforating a metal foil or a film, such as a polyamide film or a polyvinyl alcohol film, having an oxygen penetration degree of <=300 ml/m2.atm.24 hr under conditions of 20 deg.C-65% RH, and has a pore diameter of 0. 01 to 5 mm and an opening area rate of 0.0001 to 20%. A resin such as polyethylene or an ionomer resin is preferably used for the sealant layer.

Title: Lens and its holder
Inventor: YAMADA NOBORU
IPC: G02B7/02
Filed: 1982-08-05
Abstract: PURPOSE:To prevent the change in the shape of a lens body owing to a change in temp. and to fix the lens in a lens frame by providing plural projecting lines of a narrow width in the lens body and decreasing the frictional resistance in the radial direction in the stage of mounting the lens frame. CONSTITUTION:Projecting lines 33 are formed integrally on the contact surface of a lens 38 with the cylindrical part 32 of a lens frame. The contact area between the lens 38 and the low friction member 37 of the part 32 is decreased and the frictional resistance in said contact part is decreased when the lens 38 is fixed to a lens frame 31. Therefore, the expansion of the lens 38 owing to a change in temp. is easily and surely absorbed by the contact part of the lines 33, and the lens can be fixed to the lens frame in a way as to avoid deformation of the lens 38 owing to the hange in temp. of the body. The similar results are also obtained by providing recessed lines on the contact surface side with a retaining ring 35.

IPC: H01L21/223
Filed: 1991-06-10
Abstract: PURPOSE:To form evenly diffused layers by a method wherein, after Ga or Al ions are inaplanted into a uneven surface region of a semiconductor substrate such as a trench structure, said surface is successively covered with an oxide film, a nitride film and another oxide film to be annealed later. CONSTITUTION:A trench 2 is dry-etched in a silicon substrate 1 to be implanted with Ga ions making a specific angle with a perpendicular axle to the substrate surface for the formation of an ion implanted region 6. Next, the surface of the substrate 1 including the inner surface of the trench 2 is successively covered with an oxide film 71, a nitride film 8 and another oxide film 72. Next, after performing the annealing step in nitrogen atmosphere, the oxide film 72, the nitride film 8 and the other oxide film 71 are removed using fluoric acid, etc. Through these procedures, the Ga ions can be contained in the nitride film 8 in even concentration using the external diffusion phenomenon and the lateral directional diffusion caused in the annealing step after the Ga ion implantation step thereby enabling an even and shallow junction to be formed in the non- flattered surface region by the rediffusion phenomenon from the nitride film 8.
