Title: Semiconductor device and its manufacture
Inventor: NAKAOKA YUKIKO
IPC: H01L25/065
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To laminate semiconductor elements mutually, without being affected by the size and shape of a semiconductor element. SOLUTION: A pair of semiconductor elements 11, 12 facing each other are jointed by a projection electrode 13, an electrode 18 of the lower semiconductor element 12 and an electrode 19 of a supporting substrate 14, whereon a semiconductor element is mounted are connected by a looped metallic fine line 15, and a height Tb of a projection electrode is made larger than a height Tw of the metallic fine line. Thereby, even if an electrode of the lower semiconductor element 12 is covered with the upper semiconductor element 11, the metallic fine line 15 does not come into contact with the upper semiconductor element 11 and connection from the electrode 18 of the lower semiconductor element 12 to the electrode 19 of the supporting substrate 14 is made possible.  Thereby, it is possible to eliminate restriction in size and shape of a semiconductor element which are factors for deciding the combination of lamination and to realize a semiconductor device with a high density mounting structure in which arbitrary semiconductor elements are mutually laminated.

Title: Crystal oscillation circuit
Inventor: KOMATSU TAKEO
IPC: H03B5/36
Filed: 1978-04-27
Abstract: PURPOSE:To obtain an oscillation circuit which features a small amount of power consumption and low minimum operation voltage by providing the divider circuit  and the bias voltage generator circuit to the oscillation circuit consisting of P- and  N-type MOS transistors Tr and a crystal oscillator. CONSTITUTION:The 1/2 divider circuit 8 is driven by the output of the oscillation circuit consisting of P-type MOSTr1 and N-type MOSTr2 and crystal oscillator 5, and negative voltage circuit 9 is driven by the output of circuit 8. The output of circuit 9 is connected to the substrate of Tr2, and the backward bias is applied between the substrate and the source of Tr2. As circuit 8 is not operate yet at the oscillation start time, circuit 9 does not produce the negative voltage with the substrate of Tr2 featuring the same earth potential as the source. And the minimum operation voltage gives the oscillation start at a low level since the sum of the  threshold voltage of both Tr is set at a low level. When circuit 8 operates and the  negative voltage is produced from circuit 9, Tr2 is biased in the opposite direction.  And the sum of the threshold voltage becomes higher than the original set level,  thus the power consumption being reduced as shown in the figure.
