Patent ID: 8790470

Claim:
A semiconductor processing apparatus, comprising: a process chamber configured to accept a substrate for processing; and a supercritical material supplying unit configured to supply a first material in a supercritical condition to the process chamber, the supercritical material supplying unit comprising a first fluid path to provide the first material from a first source to the process chamber; a first pressure pump within the first fluid path; a second fluid path to provide a second material from a second source to the process chamber, the second fluid path disposed between the second source and a first location along the first fluid path upstream of the process chamber to provide a mixture of the first material and the second material downstream of the first location; a first regulator disposed in the first fluid path between the first location and the process chamber, configured to regulate an amount of a mixture of the first material and the second material introduced into the process chamber; and a first temperature control jacket disposed around at least a portion of the first fluid path between the first location and the first regulator, wherein the first pressure pump and the first temperature control jacket are configured to maintain temperature and pressure of the mixture of the first material and the second material so that the first material is above a critical point.
