摘要： A 1-chip microcomputer having a built-in nonvolatile memory includes at least one erasable flash memory provided in a memory space of the microcomputer, a boot ROM for storing an initial program to start up the 1-chip microcomputer and a transfer program to transfer the initial program to the flash memory, and control means for, when the flash memory stores no program, transferring the initial program to the flash memory in accordance with the transfer program and subsequently removing the boot ROM from the memory space. Consequently, even if a new program is additionally stored to the nonvolatile memory in the 1-chip microcomputer, the additional program can be carried out.

摘要： When a built-in nonvolatile memory in a microcomputer is tested, a control program prestored in a boot ROM is run upon entering a test command from an external communication device; a test program is transferred from the external communication device to a built-in RAM through a communication circuit; a control of a CPU is switched to the built-in RAM after the test program has been transferred and a test is conducted on the nonvolatile memory; and a test result and a fail log are transferred to the external communication device through the communication circuit. Consequently, the built-in nonvolatile memory in the microcomputer can be checked without leaving the test program on the chip.

摘要： In the present semiconductor device, a chip with an LSI circuit is secured to a board 3 (with the chip flipped) so as to be level. The LSI circuit on the chip is specified to operate normally only when the chip is level. Further, the back of the chip is processed so as to give stress to the chip. The chip has a reduced thickness of 50 &mgr;m or less (alternatively 30 &mgr;m to 50 &mgr;m). Therefore, when the chip is detached from the board, it deforms and is no longer level due to the stress, which prohibits the LSI circuit from operating normally. This way, the present semiconductor device ensures that no analysis can be conducted on the LSI circuit once the chip is detached.

摘要： A semiconductor device includes, on a protective film laminated on a circuit principal part, (i) a light blocking film provided so as to cover the circuit principal part, (ii) an aluminum oxide film provided so as to completely cover the light blocking film, and (iii) a light-blocking upper wiring provided on the aluminum oxide film. An attempt to exfoliate the light blocking film or the light blocking upper wiring causes the resistance-detection-use upper wiring to break or thin, thereby resulting in an increase in the resistance of the resistance-detection-use wiring. The increase in the resistance is detected by the resistance detecting circuit part, and malfunction or inoperativeness of the circuit principal part is caused in response of detection. By so doing, the circuit principal part can be protected from analysis.

摘要： A semiconductor device in accordance with the present invention includes a semiconductor element chip pressed and secured on a distortion die-pad so that the semiconductor element chip, sealed inside a package, is held in a predetermined distorted state. The predetermined distorted state is preferably downward or upward warping. The semiconductor element chip operates normally in the distorted state, and does not operate normally when the semiconductor element chip is separated from the semiconductor device, and thereby released from the distortion and laid alone. This ensures that the semiconductor element chip is protected from circuit analysis.

摘要： A method of manufacturing an SOI substrate uses an SOI substrate having a first single-crystal silicon layer, an insulating layer formed on the first single-crystal silicon layer, and a second single-crystal silicon layer formed on the insulating layer. The surface of the second single-crystal silicon layer is thermally oxidized. The second single-crystal silicon layer is controlled to have a predetermined thickness by removing the thermally oxidized surface. This step controlling the second single-crystal silicon layer to have a predetermined thickness includes the step of eliminating, by annealing, a stacking fault formed by the thermal oxidation.
