Claim:
1. A method of manufacturing a biochip, comprising: forming a microfluidic channel pattern on a fluidic substrate; depositing a sacrificial protective layer over the microfluidic channel pattern; laser drilling through-holes in the fluidic substrate; removing the sacrificial protective layer; providing a sensing wafer having a pattern of modified surface; forming a polymer pattern on the sensing wafer or on a microfluidic channel pattern side of the fluidic substrate; and bonding the sensing wafer and the fluidic substrate via the polymer pattern, after forming the microfluidic channel pattern, at a temperature less than about 100 degrees Celsius, the bonding being done in a manner that the microfluidic channel pattern on the fluidic substrate extends away from the through-holes of the fluidic substrate and along an interface of the fluidic substrate and the sensing wafer.
