Try this :

 var prefabToSpawn : GameObject;
 var spawnLocation : Vector3;
    
 function RunEvent () {
    Instantiate(prefabToSpawn, spawnLocation, Quaternion.identity);
 }

Then simply run the function at the desired time.

Like @Eric5h5 stated, Instantiate is what you will need. Heres an example using a trigger. When the Player enters the trigger we spawn ‘somePrefab’ at the players position and rotation.

public var somePrefab:Transform;

function OnTriggerEnter(other:Collider)
{
    if(other.CompareTag("Player"))
    {
        Instantiate(somePrefab,other.transform.position,other.transform.rotation);
    }
}
