摘要:
A thin reflective cylindrical baffle [20] in a radiant lamp heater is provided in the space below a plurality of heating bulbs [2,4,6] (arranged in a center position and around a middle and outer ring) and above a quartz window [12]. The baffle diameter is such that it fits within the annular space between the middle [4] and outer [6] ring of bulbs. The baffle [20] allows improved controllability of wafer temperature profile -for a wafer heated by a radiant lamp heater.

Disclosed herein are a method and apparatus for silylation of positive or negative photosensitive resist layer on a semiconductor wafer after the resist layer has been exposed to radiant energy through a mask which includes introducing a silylating agent to the wafer at high pressure over 760 torr and, usually, at temperatures less than 180° C. Increased pressure increases the rate of silylation, allows practical use of lower process temperatures, and, therefore, allows better process control. The apparatus for applying the high pressure silylation process includes a process chamber having a port and a process gas inlet; a heated substrate in the process chamber; a loadlock in fluid communication with the process chamber through the port; and a gas generator in fluid communication with the process chamber through the gas inlet.
摘要:
A processing apparatus (1300) and method wherein an integrated circuit wafer (48) is exposed to activated species generated by a first plasma (1326) which is separate from the wafer (48), but is in the process gas flow stream (1322) upstream of the wafer, and is also exposed to ion bombardment generated by a second plasma which has a dark space which substantially adjoins the surface (54) of the wafer (48). It is useful to keep the in situ plasma at a relatively low-power, so that the remote plasma can generate activated species, and therefore the in situ plasma power level can be adjusted to optimize the ion bombardment energy.

A process for photoresist ashing which utilizes the combination of remote (1326) and in situ plasma (1312, 1314) in a low pressure process module (1300) and the plasma is generated form a mixture of Oxygen and one of a group of CF₄, CHF₃, H₂, H₂O, HCl, HBr, Cl₂, and N₂O with the process chamber within the process module being generally at ambient temperatures.
摘要:
A plasma reactor apparatus and method wherein one electrode 10 of the plasma reactor, which is not the electrode 14 to which the integrated circuit wafer being processed is attached, consists essentially of monocrystalline material, preferably silicon. Preferably this is a single slice reactor. Preferably the silicon electrode 10 has holes drilled through it for gas flow.

A plasma reactor 28 for the manufacturing of semiconductor devices has powered loadlocks and a main process chamber where slices can be processed one slice at a time with pre-etch plasma treatments before the main etching processing and afterwards receive a post etch treatment. The system comprises powered loadlocks 21, 59 a main chamber, 37, vacuum pumps 29A and 29B, 31, radio frequency power supplier 51, radio frequency matching networks 53A, 53B, 53C, heat exchangers 63 and throttle valve 45 and pressure controllers, gas flow distribution 43 an microprocessor controllers 25 and 27. The semiconductor wafers are automatically fed one at a time from storage cassettes through isolation gates with articulated mechanical arms 145 to a powered entry loadlock 21 for pre-etching processes. At the completion of the pre-etching processing, the semiconductor wafer is transferred to the main chamber 37 automatically for the main etch process and then to the powered exit loadlock 45 for post etch treatment and finally to an output cassette.
