Title: Method of filling hole with selective metal film
Inventor: SATO JUNICHI
IPC: H01L21/768
Filed: 1990-02-22
Abstract: PURPOSE:To fill connection holes different in depth with refractory metal by selectively growing metal film to overfill a shallow connection hole, and then etching the overfilled part away. CONSTITUTION:A deep connection hole 4 and a shallow connection hole 5 are filled with tungsten 6 and 7 by CVD using SiH4 and WF6. When the shallow hole 4 is completely filled, the tungsten filling 7 in the hole 5 forms a nailhead 8. The tungsten filling is etched to restore the surface flatness under the conditions: SiH4(5.3 SCCM)/NO2(35 SCCM), microwave at 1kW, radio frequency at 0.5kW for bias, 7X10<-4> Torr, and magnetic field of 875 gausses. During this etching, the tungsten filling 6 in the hole 4 is not etched, while the overgrown nailhead 8 of the tungsten filling 7 above the shallow hole 5 gradually slants at side edges and finally disappears. This is because biased ECR CVD is carried out under the conditions that the etch and deposition rates are equal at the level surface, and the etch rate is greater than the deposition rate at the slant surface.

The light output of the laser diode 1 has modulation distortion, but this modulation distortion is reduced by the etalon 11 which varies in transmissivity depending upon the wavelength. The laser diode 1 and etalon 11 are installed on the same temperature control means 2 and the oscillation wavelength of the laser diode 1 and the transmission characteristics of the etalon are held stable. Further, etalon which has minus variation in the optical path length between reflecting surfaces with temperature is used as the etalon 11 and the set temperature of a temperature control means 2 is set almost to the room temperature.

Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To save the trouble and operation time of a user and to evade a formation omission by allowing a CAD device to automatically form tentative fillet surfaces as to all couples of curved surfaces to be operated without sequentially instructing curved surfaces for which fillet surfaces are to be generated on a screen by the user.

The user after selecting an automatic tentative fillet surface formation command previously inputs the radius R of a tangential arc and a value for deciding a corner. After those are inputted, the CAD(computer-aided design) device finds common ridges E1 , E2 ... of the couples of curved surfaces (F1 , F2 ), (F3 , F4 )... to judge whether or not a couple of curved surfaces form a corner, then generates tangential arcs of all the curved surfaces with the radius R inputted previously by the user, and connects those tangential arcs to form and display a tentative fillet surface on a screen. Consequently, the final fillet surface is formed.
