Title: Manufacture of semiconductor device
Inventor: EGUCHI KOJI
IPC: H01L21/3065
Filed: 1985-11-13
Abstract: PURPOSE:To prevent Si precipitation by a method wherein a barrier metal is deposited so that it may provide an excellent coverage for Si precipitation prevention and subjected to anisotropic etching as the result of which the barrier metal is retained only on the side wall of an opening. CONSTITUTION:A BPSG film 2 is formed on the entire surface of a substrate 1. The BPSG film 2 is subjected to etching that is accomplished against a desired position for the formation of an opening. Next, on the BPSG film 2, a barrier metal 3 is deposited, which is followed by anisotropic etching. With the barrier metal 3 deposited on the entire surface providing an excellent coverage, the anisotropic etching may affect the barrier metal 3 uniformly from above, as the result of which the barrier metal layer 3 is retained only on the side wall of the BPSG film 2. The barrier metal 3 thus retained contributes to preventing Si precipitation in the contact hole region. Finally, an AlSi layer 4 is formed for the completion of wiring.

Abstract: PURPOSE:To realize an optical unit which accurately holds the mutual positional relation between a solid-state image pickup element and a color separation prism by separately executing the sticking and fixing of a fixing member twice, that is, partial fixing and entire fixing. CONSTITUTION:The solid-state image pickup element 1 is set at the specified position of the color separation prism 2, and the fixing member 3 to which adhesive 4 consisting of ultraviolet-curing type resin is applied is set on the side surface of the element 1 and locally irradiated with ultraviolet rays 5 from a light source 6 to be temporarily fixed. Even when the member 3 is a rectangular parallelopiped, the ultraviolet rays 5 can be made vertically incident on the surface and ultraviolet rays 7 made incident on the adhesive 4 do not become uneven. Thus, the sticking and fixing is separately executed twice, that is, the partial fixing and the entire fixing. Thus, the positional deviation at the time of fixing is restrained regardless of the parallelism of the light receiving surface of the solid-state image pickup element and the light exiting surface of the color separation prism.

Title: Pattern detecting circuit
Inventor: YOKOTA KEIICHI
IPC: H03K5/19
Filed: 1984-12-04
Abstract: PURPOSE:To detect patterns even when the number of patterns is increased without enlarging the scale of the circuit by providing a shift register for inputting, a ROM in which reference pattern and detection completion bit are written and a circuit that compares the register output and the reference pattern. CONSTITUTION:The string of patterns to be detected is denoted as 0-m, and a pattern length is as (n) bit. At this time, the content of a ROM11 is made as shown in the table. An initial value of a counter 10 is 0, and a pattern 0 is outputted from the ROM11. When a pattern 1 of a shift register SR13 is inputted, and the output becomes pattern 0 in this state, a comparator circuit 12 detects that the output of the ROM11 and output of SR13 are the same, and makes the output 1. Thereby, the counter 10 is upped by one, and 1 is outputted as an address to the ROM11, and a pattern 1 is outputted from the ROM11. When the pattern 1 is inputted to the SR13 under this condition, the output of the comparator circuit 12 becomes 1 again. When a pattern (m) is detected, the content of address m+1 is outputted from the ROM11, and a pattern detection completion bit 14 becomes 1 and the patterns 0-m are detected.

Filed: 1986-10-28
Abstract: PURPOSE:To form a wiring layer free of unnecessary connections by a method wherein a photosensitive polyimide layer is deposited on a resist layer for the creation of a difference in height between an aluminum layer to be retained on a substrate and an aluminum layer to be removed from a resist layer. CONSTITUTION:A photosensitive polyimide layer 3 is formed on a resist layer 2 formed on a substrate 1, and a mask 4 is positioned on the photosensitive polyimide layer 3. A process follows wherein the polyimide layer 3 is exposed to a light beam for patterning and the resist layer 2 is subjected to selective removal by plasma irradiation for a pattern to match the patterned polyimide layer 3. Subsequently, by spattering or evaporation, a metal layer 5 is formed on the substrate 1. Lift-off follows whereby the metal layer 5 on the photosensitive polyimide layer 3 is removed for the formation of a wiring layer. In this design, the metal layer 5 formed on the photosensitive polyimide layer 3 is located higher than the metal layer 5 formed on the substrate 1, which eliminates the possibility of a contact between the two.

Abstract: PROBLEM TO BE SOLVED: To surely remove a pad polysilicon remainder generated in the case of forming a pad which is larger than a photoresist limit dimension and to stably form the cell of a DRAM. SOLUTION: By forming an oxidized film 13 on the entire surface and performing etch-back, a sidewall oxidized film 13 is formed on the sidewall of an oxidized film hard mask 12. At this time, a sidewall oxidized film remainder 14 is generated at a cell array end part and the gate stage part of a peripheral circuit part. Then, in order to remove the sidewall oxidized film remainder 14, a photolithographic process for protecting the oxidized film pattern of a cell part is performed. At this time, an end part 16 of a resist pattern is laid out so as to be brought onto a thickened dummy gate 7. By setting the gate the thickness equal to 2×(a+b+c+d) or larger than at this time, even when scale deviation/dimensional deviation occurs, the resist end part is not detached from a gate part and does not conceal a level difference part.  Then, the resist pattern 15 is turned to a mask, and the sidewall oxidized film remainder 14 is removed.
