Title: Aluminum wiring film for semiconductor integrated circuit device
Inventor: OKUMURA MASARU
IPC: H01L21/3205
Filed: 1991-12-11
Abstract: PURPOSE:To prevent disconnection effectively by implanting atoms of at least one of argon, arsenic and antimony into an aluminum crystal lattice so that it interrupts into the aluminum crystal lattice by the ion-implantation method for creating a compression distorted layer to a depth exceeding 10% of a film thickness. CONSTITUTION:Ions I of argon, arsenic, or antimony are ionimplanted into an exposed surface of aluminum of a wiring film 3 before cladding. The ion implantation creates a compression distorted layer 3a at a surface part which is in contact with a protective film 4 of the wiring film 3. Its depth ta should be at least 10% of a film thickness t of the protection film 3 or preferably 20% or higher. The compression distorted layer 3a is introduced into a surface part where a pulling stress becomes the maximum within the wiring film 3, thus enabling it to be relaxed or reduced. Therefore, a trouble where a wiring film is disconnected can be eliminated nearly completely.

IPC: H05K7/20
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To mount units having different heat quantity and temperature characteristics using an identical shelf by providing means for varying a plurality of deflector blades by the same rotational angle. SOLUTION: A wind deflector 30 is arranged on the upper side of an upper guide rail 18 being clamped by left and right side plates 22 along with a rotary knob 26 disposed closely to the front end of the wind deflector 30 in parallel therewith. The wind deflector 30 comprises a plurality of stripe deflector blades 3002 arranged in the horizontal direction in parallel with a back plate 20. The deflector blades 3002 are set at an arbitrary deflection angle by turning the knob 26 appropriately and the wind in a shelf can be directed in that direction. Since the cooling air flow can be varied freely by simply varying the deflection angle even when a unit having different heat quantity and temperature characteristics is mounted, an identical shelf can be used.

Title: High frequency semiconductor package
Inventor: SATO KOJI
IPC: H01L23/50
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor package in which high frequency characteristics are improved by preventing occurrence of a discontinuous impedance part between the lead of a semiconductor package and the strip line of an external circuit board for mounting the semiconductor package. SOLUTION: A semiconductor element is placed in a ceramic case part 2 provided on a heat sink 1 and leads 6 are connected with a package side strip line provided at the ceramic case part 2 and projected outward of the package. The lead 6 has wedge shape where the width of the lead decreases gradually from a base part, i.e., the projecting part from the package, toward the forward end of the lead. The semiconductor package 10 is mounted on an external circuit board 20 and the leads 6 are connected with the substrate side strip line 23 of the external circuit board 20. Since the position where the width dimensions of the lead 6 and the substrate side strip line 23 match each other depends on the width dimension of the substrate side strip line 23, characteristic impedance is matched between the lead 6 and the substrate side strip line 23.  Consequently, occurrence of discontinuous characteristic impedance is prevented between them and high frequency characteristics are improved by minimizing reflection power.
