Title: Manufacture of solid-state image pickup device
Inventor: NAGAI MITSURU
IPC: H04N5/335
Filed: 1986-03-24
Abstract: PURPOSE:To obtain a highly humidity-resistive and reliable equipment by providing an organic resin coating layer on the top of the solid-state image pickup device and by defoaming the organic resin coating layer in a passivation layer which has an inorganic thin film on the organic resin coating layer. CONSTITUTION:An organic resin coating layer 9 is formed on a substrate on which a thin film transistor and a photodetector are made by dipping or spin- coating. This is left in a vacuum for several ten minutes to several hours and is perfectly defoamed. The time of defoaming is different according to the kind of the organic resin, the thickness of the film, viscosity, etc. but it is determined by observing a greatly step-different region. If the time of defoaming is insufficient, a foam 13 remains in the great step-different region and if defoamed until such a foam 13 does not exist, no foam remains in the organic resin coating layer. An inorganic thin film 10 such as SiO2 or Si3N4 is deposited by such as sputtering on the organic resin coating layer 9 cured at 300 deg.C or lower temperature.

Abstract: PURPOSE:To prevent the inside surface of a precombustion chamber from being overcooled and as well as from being attacked by high temperature gas by a structure wherein the inner wall surface and shelf surface of a fore chamber and coated with heat insulating covering body made of heat resistant and high heat insulating stock. CONSTITUTION:The portion that the top surface of a fore chamber body 6 faces to an after chamber 10 or a shelf surface 19 and the inner wall surface 20 of a fore chamber 15 are machined-off in a precombustion chamber 9. And yet a flange-shape zirconia heat insulating covering body 21 is fitted to said machined- off portion and fixed by being pressed its outer peripheral part with the underside 22 of an after chamber body 7. During running of an engine under the condition of low cooling water temperature, the inner wall surface of the precombustion chamber 9 tends to be overcooled. However, said overcooling is prevented from developing, because the shelf surface 19 and the inner wall surface 20 of the fore chamber 15, against both of which sprayed fuel collides directly, are covered with zirconia with high heat resistance and heat insulating properties. Accordingly, the period of time, during which bluish white smoke and diesel knock at idling are developed, is shortened.
