Title: Light receiving diode
Inventor: KURIYAMA YOUICHI
IPC: H01L31/103
Filed: 1979-10-05
Abstract: PURPOSE:To obtain a high-sensitivity diode with a high nondefective rate by forming a shallow PN junction on most of the regions on the surface of a semiconductor crystal substrate when the light recieving diode is made wherein a PN junction having double depth or more is provided on a region for ohmic electrode installation. CONSTITUTION:A shallow P type layer 2 having about 0.5mum of depth for high light recieving sensitivity is formed by diffusion on an N type Si substrate 1 by surrounding the layer 2 with an oxid protective film 3. A deep P type region 6 having about 2mum of depth is formed by diffusion on a part of the layer 2 and the area of the region 6 is limited to the whole area of 1% or less. An Al electrode 4 is installed on the region 6. Next, an N<-> type layer 5 is formed on the back of the substrate 1 to compose of a diode. In this way, a PN junction produced by the layer 2 will not be damaged because the electrode 4 directly installed on the thin layer 2 as a general rule has now been formed through the thick region 6. And a nondefective rate at the time of diode manufacture will be increased.

Title: Driving method of chage-coupled device
Inventor: WATANABE YASUSHI
IPC: H01L29/768
Filed: 1978-10-23
Abstract: PURPOSE:To obtain an output which is accurately reproduced from an input signal by adding a transfer clock signal capable of giving the identical charge transfer time for one transfer cycle both at the times of low-speed driving and high-speed driving. CONSTITUTION:The X direction indicates the charge transfer direction and the Y direction indicates the depth of potential. 1 is a DC gate layer, 2 is a bent diffusion layer which connects channels, 3 is a DC gate layer, and 4 is a transfer gate. When the charges in the layer 2 are transferred to the layer 4, the quantity transferred is determined by the elapsed time from the start of the transfer and depends on the heat-radiation effect at the end. Therefore, the constant value is not reached within the normal transfer time. If the transfer time for one tansfer period varies, excess or shortage of the charges depending on the difference occurrs, generating false signals in a spike shape. Therefore, if the charge transfer time from the diffused layer is kept constant in each transfer period all the time during the driving operation, the false signals can be prevented and the input signal is accurately reproduced to become the output signal.
