Title: Semiconductor device having ink jet function, manufacture thereof, ink jet head using it, ink jet recorder, and information processing system
Inventor: HAYAKAWA YUKIHIRO
IPC: B41J2/05
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To enhance accuracy of the distance between an ink supply opening and an energy generating element by providing an ink ejection energy generating element on an Si substrate having a defect-zero layer and a layer where oxygen deposits exist and conducting the an ink supply opening with an ink channel through a through hole. SOLUTION: An Si substrate 1 is subjected to heat treatment in high temperature inert gas atmosphere and IG processing for confining contaminant impurities and then interstitial oxygen in the device active region in the vicinity of crystal surface is diffused outward to lower the concentration and to grow the nucleus of oxygen deposit in second stage heat treatment. A wafer cross-section structure is thereby obtained where a defect-zero layer(DZ layer) having no oxygen deposit exists in the vicinity of the surface of an Si crystal wafer and oxygen deposits(OP) are scattered on the inside thereof. An ink supply opening 4 is then made from the rear surface by anisotropic etching. Since impurities or crystal defects 2 of substantially same size are distributed uniformly, ink supply openings 8 can be made uniformly.

When the maximum roughness exceeds the above-mentioned range the same becomes a craterlike spot locally. When the roughness density is lower than the above-mentioned range, the same becomes apt to adhere to the film and when it exceeds the above-mentioned range, this becomes the cause of the generation of the scratch.

Abstract: PURPOSE:To contrive to improve the electric properties of a bipolar Tr and a MISFET, by a method wherein the thickness of an epitaxial layer in which bipolar transistor Tr is provided, is made thin, and the thickness of the epitaxial layer in which a MISFET is provided, is made thick. CONSTITUTION:Epitaxial layers 20 are formed on an n type semiconductor sustrate 18, and a bipolar Tr1, a p-channel type MISFET7 and an n-channel type MISFET are formed on the layers 20. The gain zone area of the Tr1 can be enlarged by making the thickness of the layer 20 thin as possible, and the collector saturation resistance of it can be made small. In the meantime, the operation speed of the FETs7, 12 can be improved by making the joining capacitance between source drain areas 10, 15 and well areas 11, 16 small as possible. This joining capacitance is largely effected by the impurities density in the wall areas 11, 16. But the impurities concentration of the areas 11, 16 increases by the impurities which diffuse by the heat added while manufacture. Accordingly, this can be prevented by making the thickness of the layer 20 large.
