    • To realize a GNSS receiver that can perform further optimal correlation processing on a positioning signal phase-modulated by a CBOC signal. A correlation processing module 32 performs correlation processing between a baseband signal and a BOC(1, 1) replica code to output a BOC(1, 1) correlation data, and also performs correlation processing between the baseband signal and a BOC(6, 1) replica code to output a BOC(6, 1) correlation data. A synthesis module 33 uses a BOC(1, 1) synthesizing ratio coefficient G11 and a BOC(6, 1) synthesizing ratio coefficient G61 to synthesize the BOC(1, 1) correlation data with the BOC(6, 1) correlation data, and outputs the synthesized correlation data to a calculation module 30. The calculation module 30 detects a reception environment based on the synthesized correlation data, sets a BOC(1, 1) synthesizing ratio coefficient and a BOC(6, 1) synthesizing ratio coefficient based on the reception environment, and supplies them to the synthesis module 33.

    • In order to enable a burn-in test in a wafer state even if a semiconductor wafer has a number of bonding pads on every chip, bumps (15) are brought into contact with bonding pads (5c) of all chips (5b) provided on a semiconductor wafer (5), so that voltages are simultaneously applied to all chips. The bumps (15) are arranged on a translucent polyimidc film (10) in mirror image relation to the bonding pads (5c), so that the former are aligned with the latter with alignment marks (34a, 34b) through an opening (11a) and the polyimide film (10) with a light-optic microscope (13). A heater (14) is brought into dose contact with the back surface of the semiconductor wafer (5), to heat the same. Thus, potential defective chips can be screened before assembling steps, to reduce the cost. Failure analysis can be quickly performed with excellent maintenance on a process line, to improve the yield and the throughput.
