#6 LED Light Manufacturing Process

Step 1 Making semiconductor wafer

1. Initially semiconductor wafer is made, the composite material like GaAs, GaP, etc are determined by the color of LED being manufacture.

The crystalline semiconductor is developed in high temperature and high-pressure chamber.

Gallium, arsenic, and/or phosphor are purified and mixed together in high temperature and high-pressure chamber.

2. Liquid encapsulation: The components are liquefied and press together and then they are forced into solution. To keep them from escaping in the chamber they are covered with the layer of boron oxide which seals them this process is called as liquid encapsulation.

After the element is mixed well and form a uniform solution. A rod is dipped into the solution and pulled out from chamber slowly. While pulling solution cools and forms a long crystalline ingot of GaAs, GaP, or GaAsP.

3. Wafer polishing: the boule is sliced into thin (approximately 10 mils) wafers of semiconductor.

Wafers are polished until its surface became smooth so wafers can rapidly accept more layers of a semiconductor on the surface.

4. Cleaning of wafer: manufactured wafers are cleaned through rigorous chemical and ultrasonic process using various solvents; this process removes the organic matters that may settle on the polished wafer surface.

This cleaning process will give the better LED.

Step 2 Adding epitaxial layers

5. The layers of semiconducting crystal are manufacture on the surface of a polished clean wafer this process is called Liquid Phase Epitaxy (LPE).

In this technique, semiconducting layers that have same crystalline orientation are deposited on the wafer.The layered wafer rest on the graphite slide which pushed channel under of molten liquid

Different dopants are added in the melt to creating a layer of material with various electronic densities, the deposition of layers became continues wafer’s crystal structure.

Liquid Phase Epitaxy (LPE) creates a uniform layer of material which is several microns thick.

6. After adding several layers it is mandatory to add additional dopants to alter the characteristics of diodes for efficiency and color.

Once additional doping is done wafer is again placed in a high-pressure furnace were it in a gaseous atmosphere containing the dopants like nitrogen or zinc ammonium; Nitrogen is added to the top layer of the diode to make the yellow or green light

Adding metal contacts

7. Introduce metal contact: Metal contact is introduced on the wafer.

The contact pattern depends on the design stage and diode combination (whether it is singular or combines).

Contact pattern is reproduced in photoresist resist which is a light-sensitive compound, the light-sensitive compound is distributing over the surface of the wafer. The photoresist resist is hardened by a brief at low temperature around 100oC.

The pattern is duplicated on photoresist placing it over the layered wafer and exposing the resist with ultraviolet light.

The exposed area of photoresist resist is washed with the developer and unexposed area is covered with the semiconducting layers.

8. Contact metals is evaporated in another high-temperature vacuum-sealed chamber and filled in the exposed area

The contact metal will stick to the exposed area of semiconductor wafer and photoresist can then be washed away with acetone.In result only metal contacts are remaining on the semiconductor wafer.

An additional layer of metal will add on the back side of wafers according to final mounting scheme for the LED.

Deposited metal undergoes an annealing process where the wafer is heated for several hours in the furnace with an inert atmosphere of hydrogen or nitrogen flowing through it; during this process, the bond between the metal and the semiconductor become stronger.

9. A single 2-inch wafer created in this way will have a similar pattern repeated up to 6000 times on it; this gives an indication of the extent of the completed diodes.

The diodes are cut by cleaving or sawing method, each segment cut from the wafer is known as the die which is a difficult process having lots of error.

Splitting or cutting results in far less than 6000 total useable LEDs and is one of the greatest difficulties in constraining generation expenses of semiconductor gadgets.

Step 3 Mounting and packaging

10. Individual dies are mounted on the approximate package; it mounted on two metal leads of two inches long.

The back of the wafer is coated with metal lead to form an electrical contact with lead it rests on. A thin gold wire is soldered to other lead and ware bonded to pattern contact on the surface of dies.

In wire bonding, the finish of the wire is pushed down on the contact metal with a fine needle. The gold is sufficiently delicate to twist and adhere to a like metal surface.

11. Finally, the entire assembly is sealed with plastic, the wire and dies are hung inside the mold that shaped according to an optical requirement of package.

Mold is filled with epoxy or liquid plastic and package is completed.
