LED Light manufacturing process

Making semiconductor wafer

1. In the first step, a semiconductor wafer is prepared, the composite materials like GaAs, GaP, etc are selected on the basis of the color of the LED that is being manufactured.

The crystalline semiconductor is made at high temperatures and using a high-pressure chamber.

Gallium, arsenic, and/or phosphor are purified and mixed using conditions that need high temperature and high-pressure.

2. Liquid encapsulation: The components are liquefied and pressed together and then they are forced into solution. To prevent their escape from the chamber they are covered using a layer of boron oxide which blocks it and this method is called liquid encapsulation.

After the element is mixed properly and form a uniform solution. A rod is dipped into the solution and taken out from the chamber gently. While pulling solution is cooled and it forms a long crystalline ingot of GaP, GaAs, or GaAsP.

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

Wafers are polished properly so that their surface becomes smooth so that the wafers can rapidly accept more layers of a semiconductor on the surface.

4. Cleaning of wafer: Manufactured wafers are cleaned using rigorous chemicals and an ultrasonic process that will have various solvents; this process cleans the organic matters that may be present on the polished wafer surface.

This cleaning process will provide a better LED.

Adding epitaxial layers

5. The layers of semiconducting crystals are developed on the surface of a polished clean wafer in a process popular as LPE-Liquid Phase Epitaxy.

In this method, semiconducting layers that have the same crystalline orientation are added to the wafer. The layered wafer is placed on the graphite slide and then pushed into the channel of molten liquid.

Different dopants are included in the melt to prepare a layer of material with various electronic densities, and after the deposition of layers, it will provide a continuous wafer’s crystal structure.

Liquid Phase Epitaxy (LPE) will manufacture a uniform layer of material which is several microns hard and thick.

6. After adding many layers it is important to add additional dopants to change the characteristics of diodes for efficiency and color.

Once additional doping is done wafer is again kept in a high-pressure furnace that has a gaseous atmosphere with dopants such as nitrogen or zinc ammonium; Nitrogen is added at the top layer of the diode so that we can get the yellow or green light.

7. Introduce metal contact: Metal contact is added to the wafer.

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

Contact pattern is reproduced in photoresist which is a light-sensitive material, the light-sensitive compound is distributed over the surface of the wafer. The photoresist resist is made strong using a low temperature around 100oC.

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

The exposed area of photoresist resist is cleaned with the developer and the unexposed area is enclosed with the semiconducting layers.

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

The contact metal will adhere to the exposed area of the semiconductor wafer and the photoresist can then be washed using acetone. This will result in the presence of metal contacts on the semiconductor wafer.

An additional layer of metal will be added on the backside of the wafers according to the final mounting scheme for the LED.

The deposited metal undergoes an annealing step where the wafer is heated for many hours in the furnace with having hydrogen or nitrogen flowing through it; during this step, the bond between the metal and the semiconductor is hardened.

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

The diodes are cut by cleaving or sawing method, each segment cut from the wafer is called the die which is a difficult process and has many errors.

Mounting and packaging

10. Individual dies are mounted on the estimated package; it is mounted on two metal leads with two inches in length.

The back of the wafer is coated with metal lead to an electrical contact with a lead that will rests on.

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

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

12. Mold is filled with liquid plastic or epoxy and then it is packed.
