The window part of the cap, which is a package component made of CO alloy), is bonded to the window part of the cap using low melting point glass, but the adhesive strength between the cap and the low melting point glass is weak, and even a relatively slight impact can destroy the bonded part. It tends to be difficult to maintain the airtightness of the package.

そして、この処理時の処理液がキャップと低融点ガラス

。It has also been found that the processing liquid during this treatment acts on the bonded portion between the cap and the low-melting point glass, deteriorating the bonded portion and reducing the hermetic sealing effect.

とが難しい。(3) When manufacturing a conventional semiconductor laser device, in order to improve the adhesion between the low-melting point glass and the camp, the cap is heat-treated to oxidize the surface of the cap before the adhesion process, and this oxide is We are trying to obtain good adhesion by taking advantage of the good adhesion between glass and low-melting point glass. However, if the oxide on the cap surface is too thick, peeling may occur at the interface between the oxide and the gap substrate, impairing the airtight adhesion, while if the oxide is too thin, good adhesion between the low melting point glass and the cap will be impaired. It is difficult to obtain an oxide with an appropriate thickness.

Further, the center portion of the cap 4 is punched out to form a circular window 5. At this time, the Aβ film 2 is punched out so as to form an inner wall.

The glass plate 7 used has good parallelism and flatness so that laser light, which will be described later, can pass therethrough without being distorted.

The glass plate 7 is bonded to the cap 4 by heating (400 to 5 feet;) to remelt the low melting point glass.

is fixed to the stem 8 by ring welding performed under a nitrogen atmosphere, and a semiconductor laser device 9 as shown in the same figure (cl) is manufactured.The stem 8 is made of a metal with good thermal conductivity,
A heat block 10 made of a metal with good thermal conductivity, such as Cu, is fixed to the side surface of the package covered by the cap 4, for example. Further, a semiconductor laser element (chip) 12 is connected via a submount 11 to the upper end and side surface of this heat block IO.
is fixed. The submount ll is the chip 12
and the heat block 10. Laser light 13 is oscillated from the resonator end faces at the upper and lower ends of chip 12. Further, a light receiving element 14 that monitors the laser beam 13 oscillated from the lower end of the chip 12 is fixed on the stem 8. Further, a desired number of boards 15 are insulatively or conductively attached to the stem 8, and are electrically connected to the electrodes of the semiconductor V-za element 12 and the light receiving element 14 via wires or the like.

。Note that when welding the cap 4 to the stem 8, if the AB film 2 has low resistance and does not generate sufficient heat, a projection may be provided on the lower surface of the flange 3 of the cap 4 to ensure reliable welding. You may adopt a method that makes it possible.
このような製造方法によれば、ガラス板7とキャップ4
とは気密的に接着され、かつその接着強度も高いものと
なる。すなわち、キャップ4に被着されたAg膜2はク
ラッド法、蒸着法、めっき法によって被着されるため、
接着強度は高い。また、ガラス板7と低融点ガラス6と
は両者がガラスであることから濡れ性もよく、その接着
強度も太キい。また、A4膜2はAIで形成されている
が、Aiは本来酸化し易く、大気中に放置されるだけで
その表面は酸化されAI3 t O*という酸化膜が形
成される。この酸化膜はA[母材とは強固に接合してい
るとともに、ガラスとの濡れ性もよく接着性も高い。こ
のようなことから、ガラス板7とキャップ4とは強固か
つ気密的に接着される。また、キャップ4はステム8に
溶接によって接着されることから、気密的にかつ強固に
接着される。According to such a manufacturing method, the glass plate 7 and the cap 4
It is airtightly bonded to the substrate and has high adhesive strength. That is, since the Ag film 2 deposited on the cap 4 is deposited by a cladding method, a vapor deposition method, or a plating method,
Adhesive strength is high. Furthermore, since the glass plate 7 and the low melting point glass 6 are both glass, they have good wettability and have a high adhesive strength. Further, the A4 film 2 is formed of AI, which is inherently easy to oxidize, and just by being left in the atmosphere, its surface is oxidized and an oxide film called AI3 t O* is formed. This oxide film is strongly bonded to the A[base material and has good wettability with glass and high adhesion. For this reason, the glass plate 7 and the cap 4 are firmly and airtightly bonded. Further, since the cap 4 is bonded to the stem 8 by welding, it is bonded airtightly and firmly.
したがって、ガラス板7とキャップ4とが前記のように
気密的にかつ強固に接着されることもあって、チップ等
は気密的に封止(パッケージ)され、かつ各接着部の機
械的強度も高くなる。この結果、比較的軽微な衝撃等で
は最も機械的強度が低いと推定できる低融点ガラス6と
キャップ4との接着部分は破損せず、半導体レーザ装置
の耐湿性が向上する。また、耐湿性の向上によって、半
導体レーザ素子、受光素子の劣化も起きにくくなり、半
導体レーザ装置の信頼性の向上、長寿命化が図れる。Therefore, since the glass plate 7 and the cap 4 are bonded airtightly and firmly as described above, the chips etc. are hermetically sealed (packaged) and the mechanical strength of each bonded portion is also maintained. It gets expensive. As a result, the adhesive portion between the low melting point glass 6 and the cap 4, which is estimated to have the lowest mechanical strength, is not damaged by a relatively slight impact, and the moisture resistance of the semiconductor laser device is improved. Further, due to improved moisture resistance, deterioration of the semiconductor laser element and the light receiving element is less likely to occur, and reliability and longevity of the semiconductor laser device can be improved.
また、キャップ4と低融点ガラス6との密着性向上の結
果、キャップ40表面にAu (金)あるいはNi等を
めっきする場合であっても、前処理の酸洗い時の処理液
に対して強くなり、キャップ4と低融点ガラス6との機
械的強度低下は起き難くなる。このため、めっき処理に
起因する気密性低下は生じ難くなる。In addition, as a result of improved adhesion between the cap 4 and the low melting point glass 6, even when the surface of the cap 40 is plated with Au (gold), Ni, etc., it is resistant to the processing solution during pickling in pre-treatment. Therefore, mechanical strength reduction between the cap 4 and the low melting point glass 6 is less likely to occur. Therefore, deterioration in airtightness due to plating treatment is less likely to occur.
また、このような半導体レーザ装置はその製造時、低融
点ガラスに対する接着性向上処理としてのキャップの酸
化処理が不要となるため、工程数低減圧よる生産コスト
の軽減化が図れる。Further, when manufacturing such a semiconductor laser device, oxidation treatment of the cap as a treatment for improving adhesion to low-melting point glass is not necessary, so production costs can be reduced by reducing the number of steps and pressure.
〔実施例2〕

きる。[Embodiment 2] FIG. 2 is a sectional view showing a semiconductor laser device according to another embodiment of the present invention. In this embodiment, the cap 4 is manufactured from a cap manufacturing material provided with the Aβ film 2 on the front and back surfaces. This semiconductor laser device has the same effect as the above embodiment, but since the A film 2 is also provided on the outer surface of the cap 4, this AI film 2 can be used as an oxidation-preventing protective film for the cap 4. 9, a new effect can be obtained in that the conventional plating process can be abolished.
〔実施例3〕
第3図は本発明の他の実施例による半導体レーザ装置を
示す断面図である。この実施例ではキャップ4の外面に
のみA7膜2を設けた例を示す。[Embodiment 3] FIG. 3 is a sectional view showing a semiconductor laser device according to another embodiment of the present invention. This embodiment shows an example in which the A7 film 2 is provided only on the outer surface of the cap 4.
したがって、ガラス板7はキャップ4の外側に低融点ガ

度化が図れる。また、製造にあっては、キャップの酸化
処理工程、キャップのめつき処理工程を廃止できること
がら生産コストの低減が図れる。Therefore, the glass plate 7 has a structure in which the glass plate 7 is bonded to the outside of the cap 4 using the low melting point glass 6. Similar to the first embodiment, this semiconductor laser device can achieve improved moisture resistance, longer life, and higher reliability due to improved bonding strength between the cap 4 and the glass plate 7. Further, in manufacturing, the oxidation treatment process of the cap and the plating treatment process of the cap can be eliminated, so that production costs can be reduced.
また、キャップ4とステム8との溶接にあっては、Fe
とFe系合金が溶接されるため、APとFeとの接触に
よるものよりも接触抵抗が太きい。In addition, when welding the cap 4 and the stem 8, Fe
Since the AP and the Fe-based alloy are welded together, the contact resistance is greater than that due to the contact between AP and Fe.
したがって、キャップ4の鍔部3にグロジェクションを
設けなくとも良好な溶接(気密的溶接)ができる効果が
ある。Therefore, there is an effect that good welding (airtight welding) can be performed without providing a glojection on the flange portion 3 of the cap 4.
