IPC: H01L23/48
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of bondability at wire bonding in a semiconductor device, where a bending part is positioned in resin and a lead terminal is derived straight. SOLUTION: A protruding part 7 and a recessed part are formed in a heat block 8. First and second bending parts 20 and 21 are formed in an island lead 4, and a step is formed. Then, the lead frame is installed on the heat block 8 after a semiconductor chip 1 is die-bonded on the island 2. A wire 11 is bonded to the electrode pad of the semiconductor chip 1 with a tool 9. Since the second bending part 21 of the island lead 4 escapes to the recessed part 22, the rear face of the island 2 is brought into close contact with the surface of the protruding part 7, and deterioration of bondability can be prevented. Similar procedure is made at second bonding to a lead terminal 3.

Abstract: PROBLEM TO BE SOLVED: To prevent the effects of adjacent of adjacent channel interference and to ensure the satisfactory communication by performing the transmission with the set transmitting power on the channel, having the largest transmitting power and then performing the transmission on the channel having the next largest transmitting power after correcting the transmitting power, if exists based on that of an adjacent definite channel. SOLUTION: A power correction circuit 40 first searches for the channel that has the largest transmitting power and then defines the transmitting power of the channel. Then the circuit 40 searches for the channel that has the next largest transmitting power, calculates a transmitting power ratio P1/P2 between the channel and its adjacent definite channel if exists and sets the transmitting power of the channel at a level of 1/T times as high as the transmitting power P1 of the adjacent definite channel of the ratio P1/P2 is larger than the prescribed threshold T. Thereafter, the processing is repeated similarly. Thus, the circuit 40 searches for a channel, that has the large influence of its adjacent channel interference and corrects the transmitting power of the searched channel.
