Title: Semiconductor device
Inventor: NIWA YOSHITAKA
IPC: H01L21/60
Filed: 1990-04-20
Abstract: PURPOSE:To obtain semiconductor devices having no fear of disconnection by forming bonding pads in a protruding state in the vertical direction against the surfaces of package boards, and constituting inner leads in parallel to semiconductor chips. CONSTITUTION:A bonding pad 21a of a package board 21 is formed in a bump structure, and when a vacuum chuck 31 which falls holding the rear of a semiconductor chip 10 is stopped at a position where the distance between the undersides of inner leads 12 and the surface of a polyimide film 11a coating the package board 21 is about 20mum, the inner leads 12, connected to bump electrodes 10a and protruding in the outside direction in parallel to the surface of the semiconductor chip 10, touch the bonding pad 21a almost in a horizontal state. And, no rotation moments are produced at the joints even if the inner leads 12 are pressed against the bonding pad 21a with a hot plate 32 heated to melt the tin attached to the surfaces of the inner leads 12. Consequently, it becomes possible to obtain semiconductor devices not having any fear of the inner leads being defoliated from the bump electrodes and brought into a state of disconnection.

IPC: H01L31/0232
Filed: 1978-08-30
Abstract: PURPOSE:To remove the effect of reflected light and perform stable laser oscillation by so forming a serration to a lens or optical fiber as to give a phase difference to the half of coherent light thereby performing photo coupling. CONSTITUTION:This is photo coupler constituted by a semiconductor laser 1, optical fibers 3, 5 and lenses 4, 2, wherein a serration D whose upper half and lower half are lambda/4 is formed to the lens 4 or optical fiber 5. (lambda is the wavelength of the output light of the semiconductor laser 1.) Hence, the light entered from the semiconductor laser 1 via lenses 4, 2 to the semiconductor lasers 3, 5 becomes of a phase difference of lambda/4 in the upper and lower halves and the reflected light thereof become lambda/2 in the upper and lower halves, resulting in that they mutually negate. Hence, the effect that the reflected light gives to the operation of the semiconductor laser 1 may be eliminated.
