Title: Taper etching method for aluminum film
Inventor: MITSUI KENJI
IPC: C23F1/00
Filed: 1985-06-10
Abstract: PURPOSE:To obtain a good tapered shape by etching an Al film in such a manner that a resist diminishes continuously and gradually during the etching treatment and that the etching of the Al film progresses even from the part of the intermediate layer at the end of the resist having a small pattern width. CONSTITUTION:An SiO2 film 2 is formed on the surface of a silicon substrate 1 and thereafter an Al-Si alloy film 3 contg. about 1wt% Si is formed thereon. An SiN2 film 5 is then formed as the intermediate layer on said film by a chemical vapor deposition method and thereafter the pattern of the photoresist 4 to provide a mask for a wiring pattern is formed. The SiO2 film 5 is subjected to the isotropic dry etching treatment by using a gaseous mixture composed of CF4 and O2 with the resist 4 as a mask to form the pattern of the SiN2 film 5 having the pattern width (b) smaller than the resist pattern width (a). The Al-Si alloy film 3 is then subjected to the dry etching treatment using a gaseous mixture composed of BCl3 and Cl2 to reduce successively the pattern width of the resist 4. The wiring pattern of the Al-Si alloy film 3 having the good tapered shape is thus formed.

Title: High frequency circuit board and connection method of the same
Inventor: YAMADA HIROMI
IPC: H05K1/11
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To cancel the reduced impedance by designing a distance between an end of a signal line and a ground electrode to be longer than a distance between the other part of the signal line and the ground electrode so as to provide a high impedance to the end part of the signal line. SOLUTION: The high frequency circuit board 40 has a signal line 42 and ground electrodes 44 on a dielectric board 40a apart from each other. Then a distance L1 between the signal line 42 and each of the ground electrodes 44 at the end of the signal line 42 is designed larger than a distance L2 between the signal line 42 and each of the ground electrodes 44 other than the end of the signal line 42. Since the impedance of the signal line 42 at the end is set higher by designing the distance L1 larger. As a result, a bonding part is formed by soldering a conductor wire to the end, the decreased impedance due to soldering is cancelled by the end whose impedance is set higher. Thus, a desired impedance is attained for the bonding part.
