In order to securely ground an exterior shield and reduce burden imposed on a dicing blade and the exterior shield, a method of producing a semiconductor module comprises a hole-forming step of forming a holeextending from a top surface of a sealing resin layerto a ground wiring() provided at a collective substrate, a film-forming step of forming an electrically conductive film made of an electrically conductive material so as to cover at least the top surface of the sealing resin layer, an internal surface of the hole, and the ground wiring(), and a separation step of separating from each other a plurality of individual module sections which the individual module section comprises.

Method of producing semiconductor module and semiconductor module

A digital demodulating apparatus comprises circuit components constituting a tuner that applies channel select processing to a received signal, and a demodulator that demodulates the signal to which the tuner has applied channel select processing; a power supply unit that supplies power to each circuit component; a reception condition detecting unit that detects a reception condition when the tuner receives the signal; a power adjusting unit that adjusts the power to be supplied to each circuit component by the power supply unit, on the basis of a result of the detection by the reception condition detecting unit; a fading environment estimating unit that estimates a fading environment when the tuner receives the signal; and a power controlling unit that controls the power adjusting unit on the basis of a result of the estimation by the fading environment estimating unit so that the number of times of adjustments of the power by the power adjusting unit per unit time changes in accordance with the variability of the reception condition.

A digital demodulating apparatus includes a tuner that selectively receives one of frequency bands, and a demodulator that demodulates a signal from the tuner. The apparatus further includes a measuring unit that measures on each carrier wave the intensity of noise to be contained in the signal from the tuner due to an interfering wave contained in the signal received by the tuner; a distribution estimating unit that estimates the distribution of interfering waves in at least one of the received frequency band and a frequency band neighboring the received frequency band, based on the distribution of noises in the frequency band measured on each carrier wave; a noise change deriving unit that derives a change in the intensity of noise to be contained in the signal from the tuner, to the power to be supplied to a circuit element; and a power updating unit that updates the value of the power to be supplied to the circuit element within a range in which the intensity of noise to be contained in the signal from the tuner is less than a noise reference value, based on the derived change in the intensity of noise to the power to supply.
