Abstract: A packaged semiconductor device is manufactured by a simplified manufacturing process, and is reduced in cost, in thickness and in size. A device component and a pad electrode connected with the device component are formed on a semiconductor substrate. A supporter is bonded to a top surface of the semiconductor substrate through an adhesive layer. Then, there is formed a protection layer that has an opening at a location corresponding to the pad electrode and covers a side surface and a back surface of the semiconductor substrate. A conductive terminal is formed on the pad electrode at the location corresponding to the opening formed in the protection layer. No wiring layer or conductive terminal is formed on the back surface of the semiconductor substrate. A conductive terminal is formed on a periphery of the supporter outside of and next to the side surface of the semiconductor substrate.

Abstract: The invention is directed to prevent corrosion of a semiconductor device. In the semiconductor device manufacturing method of the invention, a semiconductor substrate is etched from its back surface in a position corresponding to a first wiring formed on the semiconductor substrate with a first insulation film therebetween, to form a first opening exposing the first insulation film. Next, the insulation film exposed in the first opening is etched to form a second opening exposing the first wiring, and then the semiconductor substrate is etched to increase a diameter of the first opening and form a first opening having the larger diameter. Then, a second insulation film is formed on the back surface of the semiconductor substrate including on the first wiring through the first and second openings, and then the second insulation film covering the first wiring is etched.

Abstract: A designing method is provided for designing an electric circuit including a clock output circuit for delivering a clock signal and a plurality of processing circuits for receiving the clock signal from the clock output circuit via wirings for clock transmission so as to perform a predetermined process based on the clock signal. The method includes, as a method for designing the wirings for clock transmission to have a predetermined length, a first step of connecting wirings between each of the processing circuits and an arbitrary point (as a “first point”) so that the wirings have substantially the same length (as a “first length”), and a second step of connecting the first point to the clock output circuit by a single wire having the length that is obtained by subtracting the first length from the predetermined length. Thus, lengths of the wirings for transmitting the clock signal to the plurality of circuits are adjustable while the entire length of the wirings is minimized.

Abstract: The invention provides a semiconductor device that solves a problem of reflection of a pattern of a wiring formed on a back surface of a semiconductor substrate on an output image. A reflection layer is formed between a light receiving element and a wiring layer, that reflects an infrared ray toward a light receiving element the without transmitting it to the wiring layer, the infrared ray entering from a light transparent substrate toward the wiring layer through a semiconductor substrate. The reflection layer is formed at least in a region under the light receiving element uniformly or only under the light receiving element. Alternatively, an anti-reflection layer having a function of absorbing the entering infrared ray to prevent transmission thereof may be formed instead of the reflection layer.

Abstract: Cost is reduced and reliability is improved with a CSP type semiconductor device. A glass substrate which works as a supporting plate is bonded through an adhesive to a first surface of a semiconductor wafer on which first wirings are formed. Thickness of the semiconductor wafer is reduced by back-grinding the semiconductor wafer on a second surface of the semiconductor wafer which is opposite to the first surface of the semiconductor wafer. The semiconductor wafer is wet-etched to remove bumps and dips on the second surface of the semiconductor wafer caused during the back-grinding. Then the second surface of the semiconductor wafer is etched to form a tapered groove. The semiconductor wafer is wet-etched to reduce bumps and dips caused by the etching and round a corner of the groove. The wet-etching improves coverage of insulation film, wiring and protection film and enhances yield and reliability of the semiconductor device.
