Abstract: PURPOSE: To make via contact resistance lower by forming a resist pattern after forming a lower layer metal wiring and then selectively removing a reflection preventing film of a via contact part with the resist pattern as a mask, so that remarkable increase in via contact resistance is suppressed. CONSTITUTION: After an insulation film 2 is formed on an Si substrate 1, a lower layer Al wiring 3 having a reflection preventing film 4 is formed. Then a resist pattern 9 is formed, and then only the reflection preventing film 4 in a via contact part 7' is removed with the resist pattern 9 as a mask. Then, the resist pattern 9 is removed, and further, an interlayer insulation film 5 is accumulated. Then a resist pattern 6 is formed, and then a via hole 7 is opened on the interlayer insulation film 5 with the resist pattern 6 as a mask. After the resist pattern 6 is removed, an upper Al wiring 8 is farmed. Therefore, while EM resistance is improved and such effect as prevention of hillock is provided, low via contact resistance can be provided.

Title: Manufacture of optical element
Inventor: WATANABE KAZUAKI
IPC: H01L31/02
Filed: 1991-05-27
Abstract: PURPOSE:To prevent the soldering material from being oxidized during heat treatment by bonding a photo detector in a reducing atmosphere. CONSTITUTION:After the bonding position is determined, the surroundings of a stem 15 is filled with reducing atmospheric gas. The temperature of the atmospheric gas is set at 50 deg.C or above and 250 deg.C or below. In the case that the melting point of the soldering material 12 is 250 deg.C or below, the upper limit of the temperature of the atmospheric gas is set at the melting point of the soldering material. When the gas in the surroundings of the stem is completely substituted by the reducing hot gas, the stem is heated. At the same time, photo detectors 13A-13D are softly pressed against the stem. After the soldering material is melted, it is kept as it is for several seconds to dozens of tens minutes thus making the solder 12 affinitive for the stem 15 and the photo detectors. After the passage of the specified period of time, the gas is switched to forming gas to cool down the stem and bonding parts 14A-14B for preventing the soldering material from being oxidized during heat treatment. What's more, the photo detectors fluctuate less since the bonding strength increases remarkably.
