Abstract: PURPOSE:To prevent peeling of wires by making rough the surface of an insulating film being in contact with wiring layers under the wire region. CONSTITUTION:The upper surface of a semiconductor substrate 1 is covered with an insulating film 2 and thereafter a thick resist film 7 is formed thereon, followed by the patterning. The upper surface thereof is coated with a mixed solution 8 of the resist and SOG. Next, SOG 8 is removed, leaving porous resist 9. Using it as a mask, oxide film RIE is conducted. With this RIE, the insulating film covered with the thick resist film is not etched, but fine recessed and projected areas 10 are formed on the upper surface of the insulating film not covered with the thick resist film. Thereafter, the resists 7, 9 are removed to form wiring layers 3 using Al-Si as the main material. In this case, Si nodule 4 included in the material of Al-Si enters the recessed and projected areas 10 formed on the upper surface of the insulating film 2. Thereafter, a surface protective film is formed and a wire 6 is connected with a wiring layer 3 using Al-Si as the main material.

Inventor: MORI KOICHI
IPC: G06F9/32
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of instructions for a program in which a conditional executing instruction exists. SOLUTION: Concerning a digital signal processor for performing pipeline processing divided into three stages of an instruction fetch cycle, an instruction decode cycle and an instruction execute cycle, when decoding a conditional executing instruction through an instruction decoder 14, the value of a register A is put on a data bus while estimating the matching of conditions. Then, only when the conditions match at the time of the instruction execution cycle for the condition executing instruction, a register B fetches the value on the data bus. Thus, even before changing a condition flag Z by executing an instruction for generating the conditions in the instruction execute cycle, the condition executing instruction can be decoded and the instructions can be deleted excepting for the conventionally required 'condition generating instruction or condition executing instruction'.
