Abstract: A method of soldering a semiconductor device includes providing a substrate (102) having a first metal joining surface (106), providing a semiconductor die (104) having a second metal joining surface (114), providing a solder preform (100) having a first interface surface (110) and a second interface surface (112), arranging the solder preform (100) between the substrate (102) and the semiconductor die (104) such that the first interface surface (110) of the solder preform (100) faces the first metal joining surface (106) of the substrate (102) and such that the second interface surface (112) of the solder preform (100) faces the second metal joining surface (114) of the semiconductor die (104), and performing a mechanical pressure-free diffusion soldering process that forms a soldered joint between the substrate (102) and the semiconductor die (104) by melting the solder preform (100) and forming intermetallic phases in the solder. One or both of the first interface surface (110) and the second interface surface (112) has a varying surface profile (124) that creates voids (126) between the solder preform (100) and one or both of the substrate (102) and the semiconductor die (104) before the melting of the solder preform (100). The varying surface profile (124) may comprise a plurality of ridges (128) and channels (130) that are disposed between immediately adjacent ones of the ridges (128), wherein the channels (130) create the voids (126) in the arrangement (116) of the solder preform (100) in between the substrate (102) and the semiconductor die (104), permitting ingress and egress of the ambient atmosphere (122) within a soldering furnace (118) that contains the arrangement (116) of the solder preform (100) in between the substrate (102) and the semiconductor die (104). Performing the mechanical pressure-free diffusion soldering process may comprise a conditioning step that removes a tacking agent (108) provided between the solder preform (100) and one or both of the substrate (102) and the semiconductor die (104), wherein vapours of the tacking agent (108) may be outgassed through the channels (130). Performing the mechanical pressure-free diffusion soldering process may also comprise an activation step that introduces formic acid into the soldering furnace (118), wherein the formic acid can flow into the arrangement (116) through the channels (130) and the resulting reacted oxide can exit the arrangement (116) via the channels (130). The ridges (128) and channels (130) may have an undulating profile along a cross-section of the solder preform (100) that is orthogonal to the ridges (128).

Abstract: A field effect transistor (FET) with a very small effective channel length is made by using a first ion implantation to produce the source (18) and drain (19) regions of the FET and a second very shallow ion implantation (22) next to the source region (18) to produce the effective short channel of the FET. The effective channel of the FET is implanted to only a small fraction of the depth of the source and drain. This permits superior control over the threshold voltage of the FET and increases the operating speed of the FET.

Abstract: The circuit limits the frequency of pulses passing through it (from input 62 to output 66) by deleting any input pulse which follows too closely on the preceding pulse. A counter 116 counts clock pulses from 110, and stops at count 15. An input pulse sets flip-flop 118, which resets flip-flop 114, which allows counter 116 to cycle back to 0 and produce an output pulse. The output pulse resets flip-flop 118, which flip-flop 114, so the counter 116 stops again at count 15 awaiting the next input pulse. The output pulses cannot occur at intervals less than 16 times the period of the clock pulses.
