Title: Light-emitting device module and its manufacturing method
Inventor: NOMOTO TAKEYA
IPC: H01L31/0232
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To thin a device with a simple structure by mounting a light-emitting device and a photodetector for monitoring on a silicon substrate in a horizontal direction and in parallel. SOLUTION: A photo detector 12 for a backside incidence-type monitor is mounted on an Si(silicon) substrate 13 so that it becomes flush with a light- emitting device 11. A V-shaped groove for guiding a beam is formed at a backside 18 of the light emitting device 11, so that a backside emission beam 14 from the light-emitting device 11 is not reflected by the Si substrate 13 with transmission property, and furthermore an AR coating 15 is applied onto one side of the V-shaped groove for guiding the beam to prevent reflection. The lower part of the photo detector 12 for monitoring is subjected to skew cutting and metal coating 16 to entirely reflect incident beams from the V-shaped groove.  Then, the backside emission beam of the light-emitting device 11 once enters the Si substrate 13 and furthermore is reflected on the backside of the Si substrate 13 before being received by the photo detector 12 for monitoring, this thinning the thickness of a module body.

Title: Transistor device and manufacture thereof
Inventor: KOU RISHIYOU
IPC: H01L29/786
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To suppress the substrate floating effect and short channel effect with holding the advantages of the SOIMOSFET to obtain a transistor device operable at a low source voltage by forming a substrate, insulator layer and first conductivity type impurity layer for forming a channel at a region adjacent to the insulator layer. SOLUTION: A positive voltage applied to a lower gate 1 is set so as to form an inversion layer in a lower part of a p-type region 4, and if the voltage of a signal input to an upper gate 6 is a threshold voltage Vth, the transition of forming and fading of the layer 7 occurs. When a higher voltage than Vth is applied to the gate 6, the layer 7 is formed in the lower part of the region 4 to make the transistor switch on. When a lower voltage is applied, the transistor does not switch on. Thus, second conductivity type carriers flow and exit fast to avoid causing the substrate floating effect and the substrate impurity concn. is increased enough to suppress the short channel effect, allowing the threshold to be set independently.
