Lets just go down this list further, shall we?
integrated circuit chips
Two types were actually developed, by two different people. One using germanium and one using silicon... both based off of transistors. Are you going to say aliens gave us transistors, capacitors and resistors? It was well known that these components could be made out of silicon, before TI actually did it in the late 50s.
fibre optics
Alexander Bell had a patent for transmitting information using lightover wire about 200 years ago. But the 1850s people had realized that using two disimilar materials with different refraction indexes could contain light. By the early 1900s this was pyut into use in the dental industry using quartz rods. In 1920 a patent was filed to transmit light over transparent rods. In the 1930s actual fiber optics were in use to image the inside of the body. All that has happened since was basically experimenting with different frequencies of light.
stealth
This basically falls into two categories.
1) Calculating reflections - How to do this has been known since the mid 1800s. Computers simply made it so these calculations weren't by hand.
2) Materials - The most obvious and widely used is radar absorbing paint. This has been (and still is) under major research in most large universities in the US.

lasers
Were suggested by Einstein in 1917, as a direct result of astronomical spectroscopy observations. A working model was even made a few years later. These weren't put to further use until after the microwave was in use, because it provided an easy way to create stimulated emissions. These results were directly applicable to light.
kevlar
The result of 14 years of research by Stephanie Kwolek, which is well documented in scientific journals. She researched low-temperature condensation polymers, of which Kevlar happens to be one. It should be noted that even after she patened Kevlar, it couldn't be mass produced for another 6 years.
DNA engineering
Not sure exactly what you mean by this. The discovery of DNA and it's future use is one of the most documented fields. do you care to be more specific on what you think is actually supplied by ETI?
Of those listed above, only stealth was developed mostly in a secret enviroment... and even that was based on open academic research.
