IPC: H01S5/223
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce the threshold current of a semiconductor laser device having a 780 nm band InGaAsP well layer. SOLUTION: A well layer is formed of InGaAsP whose P composition is smaller than 0.55 but equal to 0.51, and spinodal decomposition is restrained from occurring when InGaAsP is grown.

An active region 15 is prevented from deteriorating, and a threshold current is reduced, so that a wavelength 780 nm band InGaAsP well layer semiconductor laser device which operates stably for a long hours, outputting a high power of 100 mW or above can be obtained. Furthermore, a tensile strain of -1.2% is introduced into a barrier layer inside the active region 15 so as to make up for stress caused by the compressive strain of the well layer, by which the semiconductor laser can be improved in reliability when it outputs a high power.

Title: Semiconductor device and data processor
Inventor: OTANI HIDENARI
IPC: G06F15/78
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To shorten charge/discharge time for bit lines to which nonvolatile memory cells are connected and to accelerate read of stored information from the nonvolatile memory cell. SOLUTION: Main/sub-bit line structure is premised, clamp voltage is supplied to main bit lines (MB0 to MBm) from voltage supply elements (QPC0 to QPCm) in a period before and after read operation for a nonvolatile memory cell (MC). In parallel to the above, sub-bit lines (LB00 to LBkm) are discharged by discharge elements (QD00 to QDkm). Since pre-charge of the main bit lines from a ground level is not required in the read operation of stored information, read operation time can be shortened. Thereby, the operation speed of a nonvolatile memory is increased. As the drain (sub-bit line) of a memory cell is held at a ground potential, a problem of memory disturbance is not caused.
