Title: Fabrication of semiconductor device
Inventor: IWAI KIWAMU
IPC: H01L21/3065
Filed: 1993-08-27
Abstract: PURPOSE:To provide a method for fabricating a semiconductor device in which a hole of desired profile can be made by single step. CONSTITUTION:During then etching process of a contact hole in first and second layer metallizations, SiO2 is deposited on the aluminium wiring 1 and coated with a photoresist mask 3. Dry etching of SiO2 2 is then started using CHF3 and when CHF3 is fed at 100% for 15sec according to an etching sequence, the edge part is tapered at 60 deg. or less with respect to a horizontal plane and an opening is formed. An etching gas producing a small quantity of polymer product, i.e., CF4, is then added stepwise by 20%, 30%, 50%, and 70% and fed, respectively, for 15sec, 15sec, 60sec, and 15sec. Finally, 100% CF4 gas is fed and the operation is continues until a required vertical etching arrives at the electrode (Fig. (d)). This method retards decrease of contact area while simultaneously retards increase of contact resistance.

The sizing former is depressed on the melt parison so that the melt parison cannot be deformed to a great extent by the frictional resistance between the melt parison and the sizing former at the time of molding and so that the both cannot be fused to each other. It is effective that the sizing former is mounted at a position 10-100mm lower than the lower end of the die (a). It is effective that the depressing part of the sizing former on the melt parison (e) has a length in a range of 1-80mm.

Filed: 1985-10-23
Abstract: PURPOSE:To reduce the unevenness of density without altering the deflection amount of a printing hammer, by differentiating the excitation widths of drive excitation signal applied onto a plurality of printing units. CONSTITUTION:Two kinds of excitation signals T1 and T2 having different excitation widths are applied to a hammer driver 12. As to the hammer driver 12, the current I1 of a width T1 is applied to the printing unit near both ends of a printing head 13 depending by on the excitation signal T1 of a narrow excitation width. By applying a required minimum electric energy, the printing hammer is released to carry out printing. In the other hand, the current 12 of a large excitation width T2 is applied to the printing unit at the central part of the printing head 13 dependingly on the excitation signal T2 and electric energy necessary sufficient for release of the printing hammer is applied to carry out printing. Because drive current of a broad range is thus applied to the printing head requiring much electric energy by using a plurality of kinds of excitation widths of drive current, the printing of little uneven density can be obtained.
