Title: Sub-mount of semiconductor laser element heat dissipating body
Inventor: WATANABE YASUMASA
IPC: H01S3/04
Filed: 1989-03-16
Abstract: PURPOSE:To protect a sub-mount against joining failure by a method wherein 3-5 stripes of solder layers are arranged in parallel with the direction of light emission on the laser element joining side of the sub-mount, the side faces of both the side stripes are made coincident with the side face of the laser element, and the lengths of the solder layers are made equal to that of the element in a light emission direction. CONSTITUTION:Ti/Pt/Au are sputtered in this sequence to form a sub-mount electrode 2 on both the sides of a single-side mirror polishing Si substrate 1 respectively, and a solder layer 3 is deposited thereon respectively. The solder layer 3 formed on the non-mirror polishing side of the substrate 1 is etched using a positive resist as a mask to provide 3-5 stripes 3a of solder 30-50mum in width. Both the side stripes 3a are coincident with the side faces of a laser element 4, and when the element 4 is mounted thereon, parallel spaces equal to the solder layer in length are formed between the electrode layer 2 and the element 4. By this constitution, even if there is an oxide film on the surface of the solder layer 3a, the molten solder 3a flows out as clean solder breaking through the oxide film to wet the whole face of an element electrode 6a, so that the element 4 and an Si substrate 1 are strongly bonded together.

Title: Production of nonlinear resistance element
Inventor: KURODA YOSHIKI
IPC: G02F1/03
Filed: 1988-03-17
Abstract: PURPOSE:To decrease a photoelectric effect by using a target contg. the essential component of a thin nonlinear resistance film and executing sputtering by bringing the same into reaction with the gas of an auxiliary component. CONSTITUTION:The essential component of the thin nonlinear resistance film is used as the target and the reaction sputtering is executed by using the auxiliary component as the gas. Namely, the target consisting of silicon is subjected to the reactive sputtering by using gaseous nitrogen or gaseous oxygen as a reactive gas to form the nonlinear resistance film of a silicon nitride film or silicon oxide film without contg. hydrogen. Generation of a difference in contrast in a bright atmosphere and dark atmosphere is thereby prevented in case of applying the element as an electrooptical device.

Abstract: PURPOSE:To prevent the generation of crystal defects by making the region where a semiconductor element is formed in a silicon substrate contain oxygen of 5X10<16>-1X10<18> atoms/cm<3> or less. CONSTITUTION:A silicon single system (preferably FZ crystal) of oxygen concentration 5X10<16> atoms/cm<3> or less is used for a substrate. If the substrate 21 is thermally oxidized, regions 21, 21b the distance of which from the face or the back of the substrate is within Xj have high concentration of oxygen and especially, near the face and the back where an element is to be formed has the concentration of oxygen near the value of solid solubility limit. That is, the concentration of oxygen of the regions 21, 21b is within 1/2-1 of the solid solubility limit and if thermally oxidized at 1,100-1,300 degrees, it is approx. 2X10<17>-10<18> atoms/cm<3>. Accordingly, dislocation is not propagated in the regions 21a, 21b at the time of heat treatment and no material is deposited since the concentration of oxygen is less than the solid solubility limit of oxygen.
