Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To improve the performance of optical electronic equipment mounting an optical waveguide modulator or the like, by making at least one side edge part of an optical waveguide more built up than in the center part. SOLUTION: An optical IC chip is constituted by forming an optical waveguide of specified shape on an LiNbO3 substrate 2, and has a step difference 80 (step difference generated in association with the oxidation reaction of a Ti film) on the surface corresponding to a Ti diffusion part out of the surface of the LiNbO3 substrate 26.

Title: Semiconductor integrated circuit device
Inventor: KUBO KAZUAKI
IPC: H01L27/115
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor integrated circuit device operating at an extremely low power supply voltage while sustaining the characteristics of low standby current, and the like, by lowering the threshold voltage of each required MOS transistor selectively and setting the channel length of an MOS transistor having a lower threshold voltage longer than that of an MOS transistor having a higher threshold voltage. SOLUTION: Threshold voltages Vtp, Vtn of a PMOS transistor 1 and an NMOS transistor 2 are lowered as compared with conventional values. Channel of a circuit having a lowered threshold voltage is set longer than that of a circuit having a higher threshold voltage. With such an arrangement, a sufficiently high gate bias can be applied even if the threshold voltage is elevated due to temperature drop by setting the threshold voltage at 0.60 V, for example. Furthermore, leak current can be suppressed by elongating the channel length. Consequently, a semiconductor integrated circuit device can be operated at an extremely low power supply voltage while sustaining the characteristics of low standby current.
