Abstract

Abstract Improved process installation (10) for double floating transport and processing of substrates (30), consisting of successive transporters (18) with process slots (28) positioned in between and tape (80) as transporting means for said substrates (30) and whereby tensioning means (24), (96) and (104) prevent an unallowable deformation of the transporters (18) and tape (80) during the processing with accompanying heat development.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 108 words
Method of tensioning during processing of substrates and tape combrising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber, defined beneath said substrates and tape intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; and d. tensioning said tape accordingly as the heat of processing affects said tape.
Claim 2
Dependent Claim 108 words
Method of tensioning during processing of substrates and tape combrising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber, defined beneath said substrates and tape intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; and d. tensioning said tape accordingly as the heat of processing affects said tape.
Claim 3
Dependent Claim 109 words
Method of tensioning substrates during processing of substrates and tape comprising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; and d. compressing and stretching said longitudinal passage accordingly as heat of processing alters the dimensions of said longitudinal passage.
Claim 4
Dependent Claim 109 words
Method of tensioning substrates during processing of substrates and tape comprising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; and d. compressing and stretching said longitudinal passage accordingly as heat of processing alters the dimensions of said longitudinal passage.
Claim 5
Dependent Claim 121 words
Method of tensioning during processing of substrates and tape comprising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; d. tensioning said tape, accordingly as the heat of processing affects said tape; and e. compressing and stretching said longitudinal passage accordingly as heat of processing alters the dimensions of said longitudinal passage.
Claim 6
Dependent Claim 121 words
Method of tensioning during processing of substrates and tape comprising: a. advancing said substrates and tape through a longitudinal passage defined by an elongated housing having side and end walls and supporting pairs of transporter sections positioned above and below and extending laterally across said longitudinal passage; b. introducing a pressurized gaseous transport medium through said transporter sections and into said longitudinal passage; c. injecting a pressurized processing medium into a processing chamber intermediate pairs of said transporters, while continuously removing gaseous transport medium and pressurized processing medium; d. tensioning said tape, accordingly as the heat of processing affects said tape; and e. compressing and stretching said longitudinal passage accordingly as heat of processing alters the dimensions of said longitudinal passage.
