Filed: 1989-12-15
Abstract: PURPOSE:To prevent deterioration of characteristics of an FET after a long time operation by a method wherein, after a gate electrode is formed, a dielectric film is formed, after the electrode surface is subjected to plasma discharge processing or heat treatment. CONSTITUTION:A positive type resist film 5 which is formed on the whole surface of a semiinsulative substrate composed of GaAs semiconductor single crystal and composed of organic polymer is fused and eliminated, and a metal layer 5 except an aperture part 5' is eliminated, thereby forming a gate electrode 7. The upper parts of the gate electrode 7, a source electrode 3 and a drain electrode 4, and the surface of the substrate 1 containing an exposed active layer 2 region between the source electrode 3 and the drain electrode 4 are subjected to plasma processing in oxygen gas or carbon tetrafluoride gas with a parallel plate type plasma equipment. The plasma processing in oxygen gas is performed under gas pressure of 0.48 torr and substrate temperature at 50 deg.C. The plasma processing in the carbon tetrafluoride is performed under gas pressure of 410 torr and substrate at a room temperature. A silicon nitride film 8 is formed on the whole surface of the active layer 2 by plasma CVD for 8 minutes using reaction between silane gas and nitrogen gas while the substrate 1 is heated at 230 deg.C.

Title: Method for heating steel strip in floating furnace
Inventor: SEKIGUCHI MASATOSHI
IPC: C21D9/63
Filed: 1987-12-23
Abstract: PURPOSE:To effectively execute heating of a steel strip by raising temp. of the steel strip with convection heating at the first half stage in heating zone of a floating furnace and using radiation heating together with the convection heating at the latter half stage. CONSTITUTION:In the heating zone in the floating furnace 1, the steel strip 2 is passed through between upper and lower floating nozzles 3 arranged in the furnace 1 under floating condition. Then, at the first half stage of the heating zone, the temp. of the steel strip 2 is raised to about 400-500 deg.C with convection heating caused by high temp. gas spouted from the nozzle 3. Successively, at the latter half stage of the heating zone, by using the radiation heating with radiation heating source 4 arranged between the nozzles 3 together with the convection heating, the steel strip 2 is quickly heated to the prescribed annealing temp. (for example, about 730 deg.C). By this method, the steel strip 2 can be effectively heated and unit consumption of blower and heating power is reduced and equipment cost is reduced because of shortening the furnace length.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a blank scene due to the deviation of inserting timing when a commercial message(CM) is inserted from the outside by arranging a CM block with a special function in a program progress table prepared electronically. SOLUTION: In the case that a CM block exists immediately before a roll to be transmitted next and when a present time becomes a point of time before an on-air(OA) starting time of the roll only for a pre-roll of the CM block, the reproduction and transmission of a front margin for pasting of the roll are started before the time for the pre-roll. When the present time is the OA ending time of the roll during being transmitted at present, the existence of the CM block immediately after the roll is checked and if it exists, the reproduction and transmission of a rear margin for pasting of the roll are started. Then, the present time is checked whether it is a point of time after the OA ending time of the roll only for a post-roll of the CM block or not. Then, such the processing is repeated until the present time reaches the OA ending time of a program.

Title: Method of mask alignment
Inventor: MAEI SHIGEKI
IPC: G03F9/00
Filed: 1989-12-14
Abstract: PURPOSE:To prevent bubbles from being generated between a mask and a substrate when the mask and the substrate with resist applied are vacuum- adsorbed and reduce failures in alignment due to defective adhesion so as to improve yielding by forming air vent grooves between element patterns formed on the mask. CONSTITUTION:Air vent grooves 26 are formed between element patterns 23, 23 formed on a mask 21 and the air vent grooves 26 are connected with each other.

Thus when vacuum-suction is performed with the mask 21 and the substrate 24 with the resist 25 applied adhered to each other, even if bubbles are to be generated between their face, the air is vented through the grooves 26 between the element patterns 23 and bubble is scarcely generated. Thus occurrence of failures in mask alignment can be reduce so as to improve a yielding.
